摘　　要：本文利用拉伸和压缩两种加载方式,对电解抛光和喷丸两种表面处理的试样进行X射线应力常数标定。试验结果表明,如果用2θ值法计算应力,那么拉伸加载条件下的X射线应力常数比压缩加载条件下的该常数高出10％以上。A method was described for calibrating X-ray stress constant. The specimens with surfaces electrolytically polished or shot- peened were loaded in lension or in compression.The experimental results showed that X-ray stress constant obtained under tensile loading was more than 10% higher than that under compression when 20 value method was applied to calculate stress.
