Phase composition and mechanical properties of alloys of the Al-Mg-Li-Me system
- 56 Downloads
The phase composition and the structure of semiproducts from alloys of the Al-Mg-Li-Zr-Sc (1423) and Al-Mg-Li-Cu-Zr (1430) systems are studied with the use of x-raying. The temperature of dissolution of the ternary phase in heating of ingots from alloy 1423 is determined. The results of estimation of the structure-and-phase state and of mechanical properties are used to determine the factors required for raising the process ductility of sheets from alloy 1430.
