摘要

PPROBLEM TO BE SOLVED: To accurately estimate the low-alloy steel life of a structure used under a high-temperature and high-pressure condition. PSOLUTION: In the metal tissue photograph of a sample of low-alloy steel sampled from an actual machine in operation, executed are: a linear approximation step of approximating a curved line constituting a crystal grain boundary to a straight line; a damage degree calculation step of calculating the deflection degree of crystal particles; and a life judging step of judging the life of the low-alloy steel from the calculated index value with reference to a use time-index value curve showing the relation between the index value preliminarily calculated with respect to the low-alloy steel and a use time.

要解决的问题：准确估算在高温高压条件下使用的结构的低合金钢寿命。

解决方案：在从实际运行的机器中取样的低合金钢样品的金属组织照片中，执行以下步骤：将构成晶粒边界的曲线近似为直线的线性近似步骤;破坏度计算步骤，计算晶体颗粒的偏转度;寿命判断步骤，该寿命判断步骤参考所使用的时间-指数值曲线从计算出的指数值来判断低合金钢的寿命，该使用时间-指数值曲线示出了针对低合金钢预先计算出的指数值与用途之间的关系。时间。
