通过对比实验,研究了电解加钛与经Al Ti、Al Ti B中间合金向工业纯铝熔配加钛的晶粒细化效果及其衰退行为,以及Al B中间合金对电解低钛铝合金的晶粒细化效果及衰退行为的影响,还分析了硼对电解低钛铝合金的晶粒细化和抗衰退行为的影响。结果表明,在钛含量为0.10%和0.15%的条件下,电解加钛晶粒细化作用的衰退速度比熔配加Al Ti中间合金要慢;熔配加Al Ti B中间合金细化晶粒作用的抗衰退能力则明显高于电解加钛和熔配加Al Ti中间合金;加Al B中间合金可有效提高电解低钛铝合金的细化效果和抗衰退能力,并使其明显高于电解加钛和熔配加Al Ti或Al Ti B中间合金。
Through the comparative experiment, the grain refinement effect and decay behavior of the electrolytic titanium addition and the addition of titanium to the commercial pure aluminum through the Al Ti and Al Ti B master alloys were studied, and the effect of Al B master alloy on the electrolysis of low titanium aluminum alloy Grain refinement and decay behavior. The effect of boron on the grain refinement and decay resistance of the electrolyzed low Ti-Al alloy was also analyzed. The results show that the decay rate of the grain refinement of the Ti-Ti alloy is slower than that of the Al-Ti alloy when the content of Ti is 0.10% and 0.15% The antidegradation ability of the alloy is obviously higher than that of the electrolytic titanium plus the Al Ti master alloy; the addition of Al B master alloy can effectively improve the refinement and anti-recession ability of the electrolytic low titanium aluminum alloy, and make it significantly higher than the electrolytic Add titanium and melt with Al Ti or Al Ti B master alloy.
