摘要
对不同原始组织的合金结构钢奥氏体形成过程进行了观察.结果发现,奥氏体形态有柱状、针状及羽毛状.原始组织对奥氏体形核及长大过程的影响十分敏感.
The forming processes of the austenite of alloy constructional steels with different original structures were observed.The result showed.that austenitic froms had grainy shape, needle-like shape and feather-like shape.The influence of the original structure on forming nucleus and growing process of austenite was very sensitive.
