稀土复合变质处理对Al-Si合金性能的影响
Effect of Rare Earth Complex Modification on Properties of Al-Si Alloy
摘要
Abstract
The effect of rare earth composite modification on the mechanical properties and wear resistance of Al-Si alloy was investigated by using Ce-La composite rare earth,and the influence of the cooling rate on the properties of Al-20％Si alloy was investigated.The research results show that the Al-20％Si compound modifier has double metamorphism,when the addition of rare earth Ce is 0.5％,La is 0.6％,the mechanical properties of Al-Si alloy is best,the tensile strength and elongation are 268.5 MPa and 0.52％,respectively.Ce-La composite modifier can refine the alloy,rare earth eutectic silicon is more sensitive to the cooling rate,the increase of the cooling rate can effectively refine the alloy.关键词
