| Abstract: | In this paper, the effect of cold drawing on the structure and properties of LY12 aluminium alloy bars before quenching has been studied.It is shown that cold drawing has obvious effect on the structure and properties. The coarse grains on the one side of LY12 alumimium alloy extruded bars can be reduced or eliminated by proper cold drawing. The cause and elimination methods are discussed. |
