In box annealing a ferrous alloy, the charge is usually heated slowly to a temperature below the transformationrange, but sometimes above or within it, and is then cooled slowly.
Experimental results show that the composition ratio making Angle of phase transformationrange become small can also increase the thermal analysis accuracy of cast iron chemical composition.
实验结果表明,能使相变段倾角最小的成分配比,也能提高对铸铁成分的热分析检测精度。

Implementations of this pattern vary in the range of transformation operations supported and how extensible those operations are.
