| Abstract: | In this pape,the mechanical performance in semisolid state during solidification process of Al-Si alloys have been investigted by means of a self-made apparatus.The semi-solid interval was defined based on the solid fraction ratio,The effects of some characteristic parameters,i.e,semisolid temperature interval,sttength,cracking strain on the tendentiousness hot-tearing,were discussed. |
