通过对合金粉膏块内外界面上温度变化曲线的测试 ,计算出了膏块在合金化形成过程中的热扩散率。并对铸渗合金层外表面上的温度曲线做了分析
The thermal diffusivity of plaster block during alloying process was calculated by testing the curve of temperature change inside and outside the alloy plaster block. The temperature curve on the outer surface of cast-infiltrated alloy was analyzed
