Effect of Indium on the precipitation process in Al-3.3Cu-0.7Li alloy

Zhengrong PAN

金属学报(英文版)

The effects of 0.5 wt pct In on Al-3.3Cu-0.8Li alloy were studied. Instead of T1 (Al2CuLi) phase, there was an unknown cubic phase acting as the dominant precipitates in the In-added alloy in T6 temper, which disappeared in T8 temper. The orientation relationship between this phase and ma...

Solidification Studies of 3003 Aluminium Alloys with Cu and Zr Additions

Majed M.R. Jaradeh , Torbjorn Carlbergy

材料科学技术(英文)

The effects of Cu and Zr additions, on the microstructure formation, precipitation and ingot cracking, in commercial 3003 Al alloys have been studied. The investigation was carried out by characterizing the grain structure in DC-cast rolling ingots, and studying the solidification microstructure of ...

Hardness-Lattice Parameter Correlation for Aged Al-Zn-Mg Alloys

P. Fernandez G. Gonzalez I. Alfonso I.A. Figueroa

材料科学技术(英文)

Two ternary Al-2.2Zn-0.95Mg and Al-5.5Zn-2.1Mg (in wt pct) alloys, with Zn:Mg ratios close to 2.5 were produced by conventional ingot casting metallurgy. The ingots were solution heat treated at 500°C for 0.5 h and aged at 180°C for times between 0.5 and 80 h. The structural characterization was car...
