相变诱发塑性 (ＴＲＩＰ)钢兼顾了高强度和高延展性的优点 ,因此倍受汽车工业的青睐 ,尤其适用于冲压成形。ＴＲＩＰ钢的高延展性来源于应变条件下亚稳态残余奥氏体向马氏体的转变。这一转变伴随着体积膨胀 ,导致应变期间应变硬化系数的局部增加。这阻碍了缩颈的发生 ,且最终导 Phase change induced plasticity (TRIP) steel takes into account the advantages of high strength and high ductility, so much the favor of the automotive industry, especially for stamping. The high ductility of TRIP steel stems from the metastable retained austenite to martensite transformation under strain conditions. This change is accompanied by volumetric expansion, resulting in a local increase in strain hardening coefficient during strain. This hinders the necking and eventually leads
