摘要

加钛方式不同

钛含量不同

对铝及其合金的晶粒细化效果不同。对比研究了用电解低钛铝合金、加Al 5Ti中间合金、Al 5Ti 1B中间合金及电解低钛铝合金加Al B中间合金 4种加钛方式及不同钛含量对 60 63合金的晶粒细化效果。研究结果表明 :不同的加钛方式对 60 63合金均有明显的细化效果

随着钛含量增加

晶粒逐渐变细 ;钛含量相同时

电解加钛的细化效果优于Al 5Ti中间合金的细化效果 ;当合金中含有硼时

钛含量相同时

电解加钛加Al B中间合金的细化效果优于加Al 5Ti 1B的细化效果。

Abstract

Effects of different Al-Ti master alloys

including electrolyzed low Ti-Al

Al-5Ti

Al-5Ti-1B and Al-B+electrolyzed low Ti-Al master alloys

on grain refinement for 6063 Al alloy with different Ti content were compared. It was showed that all master alloys can obviously refine the 6063 Al alloy and the grain size became finer gradually with Ti content increase. The refining effect with electrolyzed Ti-Al master alloy was superior to that with Al-5Ti master alloy in the modified Al-alloy with the same Ti content while the refining effect with both electrolyzed Ti-Al and Al-B master alloys was superior to Al-5Ti-B master alloy in the modified Al alloy with the same Ti content.
