Cu对轻质钢强韧性的影响

Effect of Cu on the Strength and Toughness of Lightweight Steel

摘要:

当下绿色低碳理念已成为主流，早已渗透社会的方方面面。汽车用钢铁行业发展至今，追求轻量化是大趋势，在满足安全的条件下可节约能耗并减少温室气体的排放。轻质钢凭借高强度、高伸长率和低密度，在汽车工业中受到了广泛地关注，成为潜力较大的新一代汽车用钢。铜作为一种增强轻质钢强度和韧性的合金元素，受到研究者的广泛关注。结合轻质钢的强韧化机理，论述了铜对轻质钢强韧性的影响，并且对未来含铜轻质钢的研究方向做出了展望。

Abstract:

At present， green and lowcarbon concepts have become mainstream and have permeated every aspects of society for a long time. Since the development of the automobile steel industry， the pursuit of lightweight is a major trend in order to meet the safety conditions， can save energy consumption and reduce greenhouse gas emissions. Lightweight steel with its high strength， high-elongation， and low density， has received depread attention in the automobile industry and has become a new generation of automobile steel with a huge potential. Copper， as an alloying element to enhance the strength and toughness of light steel，has attracted much attention from researchers. Combined with the strengthening and toughening mechanism of light steel， this paper discusses the influence of copper on the strength and toughness of light steel and gives a prospect of the future research direction of copper-containing light steel.
