  • 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. Keywords Metals · Casting · ADI · Heat treatment · Mg2Cu particles 1 Introduction light/heavy trucks, construction and mining equipment, railroad, agricultural, gears and crankshafts, and brackets, Austempered ductile iron (ADI) belongs to the spheroidal among others [5–7].

  • The Stainless Steel Family
    The Stainless Steel Family A short description of the various grades of stainless steel and how they fit into distinct metallurgical families. It has been written primarily from a European perspective and may not fully reflect the practice in other regions. Stainless steel is the term used to describe an extremely versatile family of engineering materials, which are selected primarily for their corrosion and heat resistant properties. All stainless steels contain principally iron and a minimum of 10.5% chromium. At this level, chromium reacts with oxygen and moisture in the environment to form a protective, adherent and coherent, oxide film that envelops the entire surface of the material. This oxide film (known as the passive or boundary layer) is very thin (2-3 namometres). [1nanometre = 10-9 m]. The passive layer on stainless steels exhibits a truly remarkable property: when damaged (e.g. abraded), it self-repairs as chromium in the steel reacts rapidly with oxygen and moisture in the environment to reform the oxide layer. Increasing the chromium content beyond the minimum of 10.5% confers still greater corrosion resistance. Corrosion resistance may be further improved, and a wide range of properties provided, by the addition of 8% or more nickel. The addition of molybdenum further increases corrosion resistance (in particular, resistance to pitting corrosion), while nitrogen increases mechanical strength and enhances resistance to pitting. Categories of Stainless Steels The stainless steel family tree has several branches, which may be differentiated in a variety of ways e.g. in terms of their areas of application, by the alloying elements used in their production, or, perhaps the most accurate way, by the metallurgical phases present in their microscopic structures: .

The effects of Cr addition on bainitic transformation, microstructure, and properties of low carbon bainitic steels were investigated by dilatometry, metallography, X-ray diffraction, and a tensile test. The results show that Cr addition hinders the isothermal bainitic transformation, and this effect is more significant at higher transformation temperatures. In addition, Cr addition increases the tensile strength and elongation simultaneously for austempering treatment at a lower temperature. However, when the austempering temperature is higher, the strength increases and the elongation obviously decreases by Cr addition, resulting in the decrease in the product of tensile strength and elongation. Meanwhile, the austempering temperature should be lower in Cr-added steel than that in Cr-free steel in order to obtain better comprehensive properties. Moreover, for the continuous cooling treatment in the present study, the product of tensile strength and elongation significantly decreases with Cr addition due to more amounts of martensite.

  • Advanced Ultra High Strength Bainitic Steels
    ADVANCED ULTRA HIGH STRENGTH BAINITIC STEELS F. G. Caballero1, C. García-Mateo1, C. Capdevila1 and C. García de Andrés1 1 Centro Nacional de Investigaciones Metalúrgicas (CENIM-CSIC), Avda Gregorio del Amo, 8- E- 28040 Madrid, Spain. Te: +34 91 5538900, Fax: +34 91 5347425, e-mail of corresponding author: [email protected] Abstract: The addition of about 2 wt-% of silicon to steel enables the production of a distinctive microstructure consisting of a mixture of bainitic ferrite, carbon-enriched retained austenite and some martensite. The silicon suppresses the precipitation of brittle cementite, and hence should lead to an improvement in toughness. However, the full benefit of this carbide-free bainitic microstructure has frequently not been realised. This is because the bainite reaction stops well before equilibrium is reached. This leaves large regions of untransformed austenite which under stress decompose to hard, brittle martensite. The essential principles governing the optimisation of such microstructures are well established, particularly that an increase in the amount of bainitic ferrite in the microstructure is needed in order to consume the blocks of austenite. With careful design, impressive combinations of strength and toughness have been reported for high-silicon bainitic steels. More recently, it has been demonstrated experimentally that models based on phase transformation theory can be applied successfully to the design of carbide free bainitic steels. Toughness values of nearly 130 MPa m1/2 were obtained for strength in the range of 1600-1700 MPa. This compares well with maraging steels, which are at least thirty times more expensive. However, the concepts of bainite transformation theory can be exploited even further to design steels that transform to bainite at temperatures as low as 150 ºC.

Steel is a composition unto 0.008% carbon is regarded as commercially pure iron those from 0.008-2% Carbon represent the steel. 7. State the condition for Gibb‟s phase rule. Pressure variable is kept constant at one atmosphere Gibb phase rule F=c-p+2; F=c-p+1(condensed Gibb phase rule). 8. Explain base metal. The element which present in the largest proportion is called the base metal 9. Differential between substitution and interstitial solid solutions. When the solute (Impurities) substitutes for parent solvent atoms in a crystal lattice, they are called substitution atoms, and the manure of the two elements is called a substitution solid solution.
