New Developments in Advanced Highestrength NEW DEVELOPMENTS IN ADVanCED HIGH-STRENGTH ShEET STEELS 30 MAY–2 JUNE 2017 KEYSTONE RESORT & CONFERENCE CENTER KEYSTONE, COLO., USA ABOUT THE PROGRAM Advanced high-strength sheet steels (AHSS) are of increasing importance, particularly to the automotive industry, where their application enables reduced fuel consumption while guaranteeing passive safety. The scope of the conference is to bring together the international community to highlight state-of-the-art research and development pertaining to AHSS. The conference will focus on the latest developments in dual phase, twinning-induced plasticity, martensitic, quenched and partitioned, medium-manganese steels, other third-generation AHSS concepts and hot-stamped steels along with recent experiences with industrial implementation and end-user application performance. A broad distribution of presentation topics is scheduled from international and domestic speakers from industry as well as academia. The conference is the latest installment in a series of product-specific conferences following the AHSS symposia in Winter Park, Colo., in 2004, Orlando, Fla., in 2008 and Vail, Colo., in 2013. WHO SHOULD ATTEND The conference should be attended by steel researchers interested in new high- strength sheet steel products, along with engineers responsible for the production and implementation of the products in steel mills, automotive facilities, and other industries, along with government and academic professionals and students.

Received: 19 October 2018; Accepted: 21 November 2018; Published: 27 November 2018 Abstract: Recently, increasing attention has been paid to alternative ironmaking processes due to the desire for sustainable development. Aiming to develop a new direct reduction technology, the paired straight hearth (PSH) furnace process, the carbothermic reduction of ore-coal composite pellets in a tall pellets bed was investigated at the lab-scale in the present work. The experimental results show that, under the present experimental conditions, when the height of the pellets bed is 80 mm (16–18 mm each layer, and 5 layers), the optimal amount of carbon to add is C/O = 0.95. Addition of either more or less carbon does not benefit the production of high quality direct reduced iron (DRI). The longer reduction time (60 min) may result in more molten slag in the top layer of DRI, which does not benefit the actual operation. At 50 min, the metallization degree could be up to 85.24%. When the experiment was performed using 5 layers of pellets (about 80 mm in height) and at 50 min duration, the productivity of metallic iron could reach 55.41 kg-MFe/m2·h (or 75.26 kg-DRI/m2·h).

Corresponding author’s email: barnabelad0110@gmail.com Abstract In this research, the corrosion response of heat treated ductile cast iron (DCI) used in the production of engine crank shaft was examined. Five samples were used in this work, one of the samples served as control sample, the remaining four samples were subjected to conventional heat treated operations of annealing, normalizing and hardening. The nodular cast irons were heated to initial austenitic temperature of 900°C, held for one (1hour) in the muffle furnace for homogenization, and samples were now cooled in furnace, air, water and oil respectively. Sodium chloride of 3.5% weight percentage solution was used as environment to study corrosion behaviour of the heat treated ductile cast irons. The microstructural images of the control and heat treated samples were resolved and various developed structures are essentially spheroidal graphite, and pearlitic matrix as in the case of the un-heat treated sample, coarse pearlite matrix for the annealed sample, fine pearlite structure for the normalized sample and partially martensitic and fully martensitic matrix for the oil and water quenched samples.

Depending on the method used (chromium deposition followed by boriding or boriding followed by chromium deposition) and the holding time, the partial or complete conversion is obtained as a result of the diffusion process. The role of the annealing temperature on transformation rates of chromium into chromium boride films was investigated. It is shown that for 1 h at 900 ◦C, the chromium layer is totally transformed. The scanning electron microscopy analysis and X-ray diffraction showed the presence of CrB and CrB2 chromium borides in addition of FeB and Fe2B iron borides.

The ferrous materials can be heated to above transformation temperature and can be heat – treated to obtain different structure. The different heat treatment processes are based on heating the material to certain temperature and employing different cooling rates. In this process, heating temperature and rate of cooling adopted plays an important role. The different processes are: Annealing • Stress-relief annealing. • Process annealing. • Spheroidsing. • Full annealing. Normalizing Hardening(Quenching) Tempering Austenite, also known as gamma phase iron (γ-Fe), is a metallic, non-magnetic allotrope of iron or a solid solution of carbon in gamma iron (γ-Fe). It forms above 7230C. It has a FCC crystal structure.

  • Optimizing Microstructure and Property by Ausforming in a Medium-Carbon Bainitic Steel

(Received on January 28, 2020; accepted on March 23, 2020) The transformation behavior and microstructure in a medium-carbon bainitic steel were investigated by combination of metallography and dilatometry. The fine micro-structural units of carbide-free bainite in non-ausformed and ausformed materials were measured by a transmission electron microscope. Mechanical stabilization of austenite in deformed material and its effect on property were analyzed by nanoindentation and tensile tests. Ausforming with a strain of 0.2 at 573 K can not only accelerate bainite transformation, but also improve the comprehensive properties. The strength and ductility of nanostruc- tured bainitic steel can be simultaneously enhanced by ausforming, which should be attributed to the refinement of bainite and the enhanced volume fraction of retained austenite. Compared to the non- deformed material, the mechanical stabilization of austenite can be optimized by ausforming, resulting in good transformation-induced plasticity effects. Also a very important advantage was that, the bainite transformation time could be minimized into practical scale by prior ausforming compared to traditional low-temperature austempering. KEY WORDS: ausforming; bainite transformation; retained austenite; property; mechanical stabilization.

To maximize the number of nanoscale MX precipitates, an ausforming procedure has been used to increase the number of nucleation sites for precipitation inside the martensite lath. Relative to standard heat treatments (consisting of austenitization at about 1040 ◦C followed by tempering at about 730 ◦C) this processing concept has enabled achieving a microstructure containing approximately three orders of magnitude higher number density of MX precipitates having a size around four times smaller in ASTM T/P91 steel. On the other hand; this TMT has little effect on the size and number density of M23C6 particles. The optimized microstructure produced by this TMT route proposed is expected to improve the creep strength of this steel. Keywords: creep resistant steels; carbonitrides precipitation; martensite; tempering; thermomechanical treatment; ferritic/martensitic steel; MX nanoprecipitates 1.

Mathaudhu, Chairperson Dr. Masaru P. Rao Dr. Peter A. Greaney Copyright by Johny Quan 2018 The Thesis of Johny Quan is approved: Committee Chairperson University of California, Riverside Acknowledgements The research work of this thesis was carried out at the Mathaudhu Research Lab, Pacific Northwest National Laboratory (PNNL) and Central Facility for Advanced Microscopy and Microanalysis (CFAMM) at the University of California, Riverside. The research was funded by QuesTek Innovations LLC under the Small Business Innovative Research (SBIR) project “Adaptation of Ferrium M54 for Personal Armor.” This research work would not have been possible without the support of many these past two years. I would like to acknowledge and thank: • Dr. Suveen Mathaudhu for not only serving as my advisor, but for guiding my research and fostering my passion for materials science and superheroes. It has been such a huge blessing to learn from you these past four years since ME 114. I also thank you for your patience with me when I would be off skydiving or staying up all night watching Luke Cage when I should have been in the lab or getting rest for a full day of work at PNNL. I look forward to many more years of friendship with you, Alicia, Leia and Maya. • Dr. Thomas Kozmel from QuesTek for providing the opportunity to work on such an exciting project and providing technical expertise these past two years.
