采用游标卡尺分别测量在不同压坯密度下烧结前和烧结后样品的尺寸,根据收缩率公式计算出样品不同方向的收缩率。收缩率计算公式为:S=(( R-R_S ))⁄R×100%
其中:S表示样品收缩率;R表示烧结前样品尺寸;RS表示烧结后样品尺寸。
A vernier caliper was used to measure the size of the sample before and after sintering at different green compact densities, and the shrinkage rate of the sample in different directions was calculated according to the shrinkage rate formula. The shrinkage calculation formula is: S=(( R-R_S ))⁄R×100% Among them: S represents the sample shrinkage rate; R represents the sample size before sintering; RS represents the sample size after sintering.
