基于正交试验的高强高导AA8000系铝合金的优化设计
Optimal Design of AA8000 Alloys with High Strength and Conductivity Based on Orthogonal Experiment
摘要
Abstract
The orthogonal experiment was used to design the composition of alloy,and the optimal alloy composition was obtained by using the binary match table.We investigated the influence of Fe,Si contents in AA8000 alloys performance via SEM,XRD,optical microscopic,and TEM,as well as their interaction.On the other hand,the impact of different micro-morphology on the electrical and mechanical performance of AA8000 alloys has been studied,and the Fe and Si interaction mechanism was theoretically analyzed.It has found that Al alloys have better electrical conductivity and higher mechanical strength when Fe=0.4wt%,Si=0.2wt% by orthogonal test.We also demonstrated that there is strong interaction between Fe and Si by forming mesophase in compound Al8Fe2Si,which reduces the influence of Si on AA8000 alloys' conductivity.关键词
