EEC-9812842斯佩尔科罗拉多矿业学院这是一个探索性研究项目，旨在加强工业/大学合作研究中心的先进钢铁加工和产品研究。这项研究将研究氮化钛在薄板坯连铸低碳钢中的析出行为，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度大于连铸或铸锭，这将对氮化钛在高温下的固相反应产生深远的影响。这将为新的高强度低合金钢合金设计提供科学依据。

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.
