研究了Ti、Ti-Mo和Ti-Nb微合金化对三种实验用低合金高强钢沉淀强化的影响。研究了连续冷却和间断冷却条件下碳化物的析出规律。结果发现，与碳化钛TiC和钛铌复合碳化物（Ti，Nb）C相比，钛钼复合碳化物（Ti，Mo）C可以强烈地保持压力级尺寸，并且对硬度的贡献最大。结果表明，（Ti，Mo）C颗粒具有良好的热稳定性。(c)2008 Elsevier B. V.保留所有权利。
The effects of Ti, Ti-Mo, and Ti-Nb microalloy additions on the precipitation strengthening in three experimental high-strength low-alloy steels have been investigated. The objective of this work was to study the carbide precipitation under the conditions of continuous cooling and interrupted cooling. It was found that titanium molybdenum complex carbide, (Ti, Mo)C, can strongly maintain manometer-scaled sizes and has the largest contribution to the hardness as compared to titanium carbide, TiC, and titanium niobium complex carbide, (Ti, Nb)C. The result emphasizes that (Ti, Mo)C particles possess an excellent behavior of thermal stability. (c) 2008 Elsevier B.V. All rights reserved.
