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.

摘要： A heat treatable 7000 series aluminum alloy has a micro-structure with a crystal grain size of 45 .mu.m or less and an aspect ratio (longitudinal/long transverse ratio of crystal grain) of preferably 4 or less, whereby its corrosion resistance is improved outstandingly by applying a solution heat treatment and hardening and subsequently, applying an aging treatment at 100 to 145.degree. C. for 5 to 50 hr, a reversion treatment at 140 to 195.degree. C. for 0.5 to 30 hr. and a re-aging treatment at 100 to 145.degree. C. for 5 to 50 hr. to thereby make an electroconductivity to 38-40 IACS %, and render the micro-structure so as to have a minimum distance for the .eta. phase on the crystal grain boundary of 20 nm or more and a maximum size for the .eta.' phase in the crystal grain of 20 nm or less.
