【Abstract】 This paper investigated the formation of austenite in 20Cr2Ni4A Steel unequilibrium structure.The nucleation and growth process of the needle-like and globular austenite have been examined by differenttemperature holding at Ac₁～Ac_3-.Influences of two austenitie shapes on the structure inheritance have also beendiscusscd.更多还原
