Hardened Aluminum Alloys MATSE 81: Materials In
Hardened Aluminum Alloys. In 1901, German metallurgist Alfred Wilm was working to harden aluminum-copper alloys. The work was not going well so in frustration he went on holiday (vacation). Upon his return, he found a harder material and after many years of work developed a commercially viable age-hardened aluminum alloy.
Heat Treating of Aluminum Alloys
series alloys contain amounts of soluble elements that far exceed solid-solubility limits. In these alloys, the phase formed by combination of the excess soluble elements with the aluminum will never be dissolved, although the shapes of the undissolved par- ticles may be changed by partial solution. Most of the heat-treatable aluminum alloy
