ABSTRACT EEC-9812842SpeerColorado School of Mines This is an Exploratory Research Project to augment the Industry/University Cooperative Research Center for Advanced Steel Processing and Products Research. The research will examine the precipitation behavior of titanium nitride in low-carbon steels produced via thin-slab casting, with the objective of developing new alloying approaches for the production of high strength steels. Because the cooling rate in thin-slab products is greater than for continuous casting or ingot casting, it is expected that this will have a profound influence on the solid state reactions of titanium nitrides at high temperatures. This should lead to a scientific basis for new HSLA (high strength low- alloy) steel alloy designs.

摘要 EEC-9812842 SpeerColorado矿业学院这是一个探索性研究项目，以加强先进钢铁加工和产品研究的工业/大学合作研究中心。该研究将研究通过薄板坯连铸生产的低碳钢中氮化钛的析出行为，目的是开发生产高强度钢的新合金化方法。 由于薄板坯产品的冷却速率大于连续铸造或铸锭，因此预计这将对高温下氮化钛的固态反应产生深远影响。 这将为新的低合金高强钢合金设计提供科学依据.
