| Abstract: | In this paper,the main work is studying the methods of measuring the grain size in 1 Cr18Ni9Ti austentional stainless steel and LY12 aluminumalloy,etc.Besides the conventional metallographical way, the measuring of the ultrasonic longitudinal wave velocity, ultrasonic attenuation,eddy-current conductivity and hardness of metal materials, the relations between these parameters and grain size will be established.The results show:the non-destructive testing is non-destructive and this way is possible and applicable. |
