The existence of such transformations depends on the alloy system in question and the diffusionprocess described earlier governs the way in which a given transformation takes place.
这种转变是否存在取决于所研究的合金系统，而某给定转变发生的方式受到前述扩散过程的控制。

This shows the diffusion of alloy elements forming carbide must be taken during the process of bainite growing.
这表明在贝氏体长大过程中存在合金元素的扩散。
