| Abstract: | Tensile property is one of the major testing items for R＆D, production and acceptance inspection of metallic materials. Under tensile testing, various strength and tensility characters are important indexes that reflect mechanical properties of these materials. In the paper, the concept and rounding off of post-fracture elongation of metallie materials going through tensile testing at room temperature were discussed. |
