摘      要：In this paper,the influence of deformation on the microstructure and low-temperature refining behavior of Al-3.5P master alloy was *** results show that the average size of AIP particles can be reduced obviously from 15.3 μm to about 2.1 μm by ***,it exhibits entirely opposite influence on refining performance when A1-3.5P master alloy was deformed at room temperature and high temperature,*** when Al-3.5P master alloy was subjected to thermal deformation,can an improvement of low-temperature refining performance be *** this condition,primary Si in A390 alloy can be refined from 137 to 21 μm,making it a potential candidate for die casting production.A mechanism associated with the transformation of particle-matrix interface during deformation has been proposed and further experiment has been designed to validate it.
