摘要
高强钢在汽车轻量化、节能减排、成本方面具有一定的优势与潜力,目前,仍是汽车的主要材料。高强钢的使用比例逐年增加,并且向更高强度方向发展,生产方式呈现出钢板"以热代冷"、零件成形"以冷代热"的低成本发展趋势,依靠亚稳奥氏体增强、增塑的第三代汽车钢成为先进高强钢的重要发展方向,然而,先进高强钢的发展给材料、工艺、装备等带来了新的挑战。
High strength steel is still the main material of automobiles,and has certain advantages and potentials in light weight,energy saving,emission reduction and cost for automobiles. The use ratio of high strength steel increases year by year and develops towards higher strength. Lower cost are important developing trend,the low cost production modes mainly reflected in hot rolling instead of cold rolling to produce sheet steel,and cold forming instead of hot stamping to produce ultra-high strength automobile parts,and so on. The third generation automobile steel,which relies on the metastable austenite enhancing strength and ductility,has become important development trends of advanced high strength steel. The development of advanced automobile steels bring new challenges to the material science,processing and equipment.
