铝锂合金的铸锭冶金（Ⅱ）

INGOT METALLURGY OF ALUMINIUM-LITHIUM ALLOYS

介绍了俄罗斯铝锂合金铸锭熔炼和铸造方法的发展和改进，评述了铝锂合金熔铸特点，熔体氧化，防护添加剂，熔剂和氩气防护，氧、碳、氮和氢等非金属夹杂，铸造裂纹（冷裂和热裂）敏感性，结晶状态，不均匀组织等方面的研究结果。

The developments and modification of ingots melting and casting methods of Al-Li alloys from Rus-sian are introduced with the emphasis on the research results of the melting feature,melt oxidation,pro-tection additions,fluxes and argon protection,nonmetallic impurities(oxygen,carbon,nitrogen,hydrogen),susceptibility to casting cracks(cold cracks and hot cracks),crystallization conditions,and in-gots nonhomogeneous structure in Al-Li alloys.
