Differential dilation curve

Under deformation condition of ε=1 2 and defining the lowest point of differential in the dilatometric curve as the recrystallization temperatures,the recrystallization temperatures raised from 645.

如将膨胀曲线的微分最低点定为再结晶温度 ,在形变量为ε =1 2的条件下 ,当加热速率由 2 0℃ /h提高到 40 0℃ /h时 ,该钢的再结晶温度由 6 45℃提高到 6 6 4℃。

The thermal dilatometric curves were tested,and thermal shock experiments were made by simulating field test.

考察了MgO-PSZ烧结后经两步或一步热处理所制材料的组织与性能,采用XRD,SEM观察分析其相组成和显微结构,测定材料的热膨胀曲线并进行模拟抗热震性试验。
