摘要
18 6 8年Чернов首先指出钢的淬火温度应在临界点a以上 ,相当于Osmond后来给出的Ac1或Ac3 。Roberts Austen(即奥氏 )在 1896年绘制出Fe C临界点图 ,接着又在 1897年给出第一个Fe C平衡图 ,其中有碳在γ Fe中的单相区 (后来Howe称之为奥氏体 )。两年后他又给出第二个Fe C平衡图 ,根据相律 ,包晶、共晶、共析三相反应都发生在一固定温度。一年后 (190 0 ) ,Bakhuis Roozeboom引入Fe3 C并根据相律绘出Fe Fe3 C亚稳平衡图 ,与现今使用的Fe
In 1868 Чернов frist pointed out that steels have to be quenched above a certain critical temperature a, corresponding to the A C1 or A C3 used later by Osmond. Roberts\|Austen in 1896 drew the critical point diagram of the Fe\|C system and in 1897 the first Fe\|C equilibrium diagram in which a single\|phase region of the solid solution of carbon in γ\|Fe exists(later called austenite by Howe). In 1899 Roberts\|Austen presented the second Fe\|C equilibrium diagram in which the peritectic, eutectic, and eutectoid three\|phase reactions, according to the phase rule, all occurred at constant temperatures. Finally, Bakhuis\|Roozeboom in 1900 produced the Fe\|Fe 3C metastable equilibrium diagram, which is basically the same as the present Fe\|C equilibrium diagram in use.
