摘要: An aluminium alloy with superior thermal neutron absorptivity contains 0.2-30 wt. % of Gd. An aluminium alloy for an wrought material with high-temperature strength contains 0.2-20 wt. % of Gd and 0.5-6 wt. % of Mg. An aluminium alloy for casting contains 0.2-10 wt. % of Gd and 6-12 wt. % of Si.

摘要: Sheets of high strength superplastic Al--Zn--Mg alloys or Al--Cu alloys which having a maximum grain size below 30 .mu.m on average are described. These alloy sheets are obtained by a method which is characterized by keeping a homogenized and hot worked ingot of the alloy at two different temperatures for sufficient times whereby a fine grain structure is formed in the alloy to impart superplasticity to the alloy.
