The microstructure and hardness were examined using optical microscopy and a Rockwell hardness tester. Rotational ball-on-disk sliding wear tests were carried out to investigate the wear behavior of austempered gray cast iron samples and to compare with conventional quenched and tempered gray cast iron samples under equivalent hardness. For the austempered samples, it was found that acicular ferrite and carbon saturated austenite were formed in the matrix. The ferritic platelets became coarse when increasing the austempering temperature or extending the holding time. Hardness decreased due to a decreasing amount of martensite in the matrix. In wear tests, austempered gray cast iron samples showed slightly higher wear resistance than quenched and tempered samples under similar hardness while using the austempering temperatures of 232 ◦C, 260 ◦C, 288 ◦C, and 316 ◦C and distinctly better wear resistance while using the austempering temperatures of 343 ◦C and 371 ◦C.

  • Role of Austenitization Temperature on Structure Homogeneity and Transformation Kinetics in Austempered Ductile Iron
    Metals and Materials International https://doi.org/10.1007/s12540-019-00245-y Role of Austenitization Temperature on Structure Homogeneity and Transformation Kinetics in Austempered Ductile Iron M. Górny1 · G. Angella2 · E. Tyrała1 · M. Kawalec1 · S. Paź1 · A. Kmita3 Received: 17 December 2018 / Accepted: 14 January 2019 © The Author(s) 2019 Abstract This paper considers the important factors of the production of high-strength ADI (Austempered Ductile Iron); namely, the austenitization stage during heat treatment. The two series of ADI with diferent initial microstructures were taken into consideration in this work. Experiments were carried out for castings with a 25-mm-walled thickness. Variable techniques (OM, SEM, dilatometry, DSC, Variable Magnetic Field, hardness, and impact strength measurements) were used for investi- gations of the infuence of austenitization time on austempering transformation kinetics and structure in austempered ductile iron. The outcome of this work indicates that the austenitizing temperature has a very signifcant impact on structure homo- geneity and the resultant mechanical properties. It has been shown that the homogeneity of the metallic matrix of the ADI microstructure strongly depends on the austenitizing temperature and the initial microstructure of the spheroidal cast irons (mainly through the number of graphite nodules). In addition, this work shows the role of the austenitization temperature on the formation of Mg–Cu precipitations in ADI.

Tensile strength, yield strength, percentage elongation and impact energy were evaluated for the as-cast and austempered samples. Microstructures were investigated using microscopy, coupled with analyzing software and a scanning electron microscopy. The specific wear of samples was tested using pin-on-disc wear testing machine. X-ray diffraction was performed to calculate the amount of retained austenite present in the ausferrite matrix. As-cast microstructure consists of ferrite and pearlite, whereas austempered ductile iron (ADI) contains a mixture of acicular ferrite and carbon enriched austenite, called “ausferrite”. Hardness and strength decreased, whereas ductility and impact strength improved with an increase in the austempering temperature.

  • Integration of Mechanics Into Materials Science Research a Guide for Material Researchers in Analytical,Computational and Experimental Methods
    Integration of Mechanics into Materials Science Research A Guide for Material Researchers in Analytical,Computational and Experimental Methods Yunan Prawoto Faculty of Mechanical Engineering UTM To my wife Anita, my daughters Almas and Alya. To all of you who cares about environment. Preface HIS book is written for my students. As an academician who returned to education after 15 years working in industry and business, I can under- T stand the hardship and difficulties for master and PhD students, as well as young researchers wanting to adopt the knowledge outside their area. While my formal education was in mechanics from bachelor until doctorate de- gree, I was lucky enough to work as an R&D manager/technician at the same time, responsible for the metallurgical department in an automotive supplier in its Detroit headquarters. I was also lucky enough to have worked for a laboratory that supports the metallurgical division of an oil company back in my early career. As a result, I can easily integrate the mechanics concept into materials science area. Among the students that I supervised, I noticed that students with pure materials background are commonly have great difficulties getting their works published, while the ones with mechanics background were able to publish their works with hardly any difficulties. Usually, it doesn’t take long for me to teach basic mechanics again, they can integrate the concept of mechanics into their research after that. By doing so, they can publish their work easier in high impact journals. This book was prepared for them to get a jump start to be familiar with a mechanics concept.

  • Ductile Iron Pipe Joints and Their Uses by Richard W
    Strength and Durability for Life® FEATURES Ductile Iron Pipe Joints and Their Uses by Richard W. Bonds, P.E. Last Revised: March 2017 Joints for iron pipe have come a long way. About 550 years ago, the first Cast Iron pipes were made with flanged joints, using lead or leather gaskets. The bell and spigot joint, which was assembled by caulking yarn or braided hemp into the base of the annular bell cavity and then pouring molten lead into the remaining space inside the bell, was developed in 1785 and extensively used until the late 1950s. The roll-on joint was developed in 1937 and was used for roughly 20 years before its manufacture was discontinued. Assembly of this joint involved a compressed rubber gasket rolled under a restriction ring, followed by caulked, square-braided jute. The remainder of the joint was packed with a bituminous compound. Today, the push-on and mechanical joints are the most prominent. The mechanical joint was developed for gas industry use in the late 1920s but has since been used extensively in the water industry. The push-on joint was developed in 1956 and represented an important advancement in the water distribution field. Several special joints have been available for years. These include ball and socket for subaqueous crossings, grooved and shouldered, and numerous variations of restrained joints. There is a much wider variety of joints available for Ductile Iron Pipe than for any other piping material, providing greater flexibility and versatility in pipeline design and installation. Push On Joints The most popular, quickest, and easiest-to-assemble joint for Ductile Iron Pipe and fittings in underground applications is the push-on joint.

The castings chosen for the project were a standard spheroidal graphite iron (SGI), and two SGI with high silicon contents, and two compacted graphite irons (CGI) with also high silicon contents. Some experiments were done for each studied cast iron as dilatometer, differential scanner calorimeter (DSC) and Laser flash. After the thermal study, a microscope analysis was done in order to obtain the nodularity, the graphite amount and the ferrite and pearlite amount of each cast iron. The goal of the project is investigate the thermal behaviour of casting with high silicon contents and find any kind of relation between the silicon content, the thermal conductivity and the nodularity. The results doesn´t report an important influence of the silicon content in the thermal conductivity. Studying the results it is concluded that in applications were high thermal conductivity is required, it is recommended cooling rates corresponding to thickness higher than 50 mm.

  • Effects of Chloride Ions on Corrosion of Ductile Iron and Carbon Steel in Soil
    www.nature.com/scientificreports OPEN Efects of chloride ions on corrosion of ductile iron and carbon steel in soil environments Received: 7 February 2017 Yarong Song1,2, Guangming Jiang2, Ying Chen1, Peng Zhao1 & Yimei Tian1,3 Accepted: 22 June 2017 Chloride is reported to play a signifcant role in corrosion reactions, products and kinetics of ferrous Published online: 31 July 2017 metals. To enhance the understanding of the efects of soil environments, especially the saline soils with high levels of chloride, on the corrosion of ductile iron and carbon steel, a 3-month corrosion test was carried out by exposing ferrous metals to soils of six chloride concentrations. The surface morphology, rust compositions and corrosion kinetics were comprehensively studied by visual observation, scanning electron microscopy (SEM), X-Ray difraction (XRD), weight loss, pit depth measurement, linear polarization and electrochemical impedance spectroscopy (EIS) measurements. It showed that chloride ions infuenced the characteristics and compositions of rust layers by diverting and participating in corrosion reactions. α-FeOOH, γ-FeOOH and iron oxides were major corrosion products, while β-Fe8O8(OH)8Cl1.35 rather than β-FeOOH was formed when high chloride concentrations were provided. Chloride also suppressed the decreasing of corrosion rates, whereas increased the difculty in the difusion process by thickening the rust layers and transforming the rust compositions. Carbon steel is more susceptible to chloride attacks than ductile iron. The corrosion kinetics of ductile iron and carbon steel corresponded with the probabilistic and bilinear model respectively. Corrosion of ferrous metals in soil is one of the major causes of durability problems of water, sewage, oil and gas distribution systems.

A custom design heat treatment setup, consisting of two units with the top unit (furnace) serving for austenitizing and the 200 L capacity bottom unit (stirred NaNO2-KNO3 salt bath) serving for isothermal treatment, was used for the experiments. It was found that austempering treatment at 290 ◦C increased the hardness of the Ni-Cu alloyed GGG-60 sample by about 44% without causing a loss in its ductility. In the case of the Mo-Ni-Cu alloyed sample, the increase in hardness due to austempering reached to almost 80% at the same temperature while some ductility was lost.
