標(biāo)準(zhǔn)簡介
This standard specifies the principle,equipment,test pieces,test conditions,test procedures,validation of test results and test report for the determination of elastic modulus,tensile strength,hardness and stress-strain curve of metallic materials based on the indentation method. This standard is applicable to thedetermination of the elastic modulus,tensile strength,Rockwell hardness and stress-strain curve in the stage of uniform deformation of metallic materials that are homogeneous,isotropic and following power-law strain hardening.It is also applicable to the conversion between the tensile strength and hardness,as well as the conversion between values of Brinell hardness,Rockwell hardness and Vickers hardness. NOTE When used to determine the stress-strain curve of a metallic material which shows obvious yielding platform or linear strain hardening,significant errors may be found in the obtained results.前言
