摘要
低合金超高强度钢因强度高、热加工工艺性好及生产成本低而广受重视。但其韧性较低,成了制约其大规模生产和应用的关键因素。简要阐述了低合金超高强度钢的国内外研究动态,重点分析了合金元素、冶炼方法及热处理工艺对其强韧性的影响,并提出了改善其韧性的方法及今后的研究方向。
Ultra-high strength low alloy（UHSLA） steels have been widely recognised for their ultra-high strength, good hot formability and low cost of manufacture, but their poor fracture toughness is a key factor to limit their commercial use. The development of UHSLA steels is briefly reviewed. The effects of chemical composition, metallurgical methods and heat treatment process on the strength and toughness of UHSLA steels are summarized. Methods of improving the toughness, which will be important topics for future research, are pointed out.
