摘　　要：断裂韧性值KIC是评定材料安全性能的主要参数,寻找KIC的估算方法就显得非常有必要。利用估算方法,既能减少断裂韧性试验的费用,又能取得评价所需要的参数值。本文简述了压力容器材料在几种不同环境下的断裂韧性值的估算方法,使得一些缺陷材料在不能通过实验获得其断裂韧性值的情况下利用估算方法间接获取,为压力容器设备的安全评定提供了方便。The fracture toughness value KIC was the main parameter to evaluate the safety performance of the material, and it was necessary to find a way to estimate the KIC. The usage of estimation method not only reduced the cost of the fracture toughness test, but also obtained the required parameters of evaluation. This paper briefly described the fracture toughness value estimation method of pressure vessel materials in several different environments, made some defect material got fracture toughness values by estimation method under the condition of its fracture toughness values not got by using the experiment, at the same time it provided the convenient for safety assessment of pressure vessel eauinment.
