摘要: 金相观察証明,1.4%C-1.4%Cr钢經1100℃奥氏体化(M_s点为112℃)和淬火后再上淬至100℃进行等温过程中,其等溫轉变产物为馬氏体。当鋼內残余奥氏体量較少(<40%)时,等溫馬氏体的形成以原有馬氏体的继續长大为主。当鋼內残余奥氏体量較大(>50%)时,等温馬氏体的形成以重新形核长大为主。等溫馬氏体也可能在原有馬氏体的某些边上形成,它的数量不大,且和残余奥氏体量无关。文中提出可能的解释。
Abstract:Metallographic investigation shows that the isothermal reaction, near M_s point (100℃) in 1.4% C-1.4% Cr steel quenched from 1100℃, takes place by martensitic transformation. The major portion of the isothermal reaction occurs by the growth of existing martensite when the amount of retained austenite is less than 40%, while occurs by the formation of new plates when it is more than 50%. Isothermal martensite may form at some preferred sites of existing plates in small amount, which is independent of the amount of retained austenite. A probable explanation is suggested.
