AbolishedDetermination of charpy impact fracture surface for metallic materials
金属夏比冲击断口测定方法
Application Summary AI generated
This standard specifies the method for determining the percentage of ductile and brittle fracture areas on the fracture surface of metallic materials after a Charpy impact test. It is applied in the metallurgical industry and materials testing laboratories to evaluate the toughness and fracture behavior of steels and other metals, particularly for quality control and acceptance testing of structural and pressure vessel materials.
