| 摘 要： | 用ＴＥＭ对低碳微钛钢中ＴｉＮ沉淀相的析出为进行研究，结果表明：铸态情况下，因Ｔｉ的偏析，ＴｉＮ呈枝晶析出；热处理过程中，析出的ＴｉＮ进一步长大。

| Abstract: | TiN precipitation from titanium microalloyed steels is studied by TEM.TiN precipitates are tree-like in Cast sample house of the Segregation of titanium during solidifyingAt heat treatment, TiN particles are growing. When the size of TiN precipitates isless than 6um,the shape of TiN is spherical. Their shape is transformed from sphere into cube along with thegrouwth of TiN precipitates.TiN precipitates strongly resist growth of austenite grains |
