由截线及杠杆定律分析可知，低碳铁素体成核并长大，剩下含碳量高的奥氏体。
Tie-line and level-law calculations show that low-carbon ferrite nucleates and grows, leaving the remaining austenite richer in carbon.
在含碳量1.5%的铁基体中主要沿晶界分布； 在含碳量3%的基体中呈均匀分布。
In composites contained 1.5%C, VC particles were along austenite crystal boundary, while others of 3%C content were distributed uniformly.
如果钢的含碳量已知，钢件合适的加热温度可参考铁碳合金状态图得到。
If the carbon content of the steel is known, the proper temperature to which the steel should be heated may be obtained by reference to the iron-iron carbide phase diagram.
