Thermal stability, determining the material ability of retaining its properties at required
temperatures over extended service time, is becoming the next frontier for aluminum alloys …

Abstract 2195 Al-Li alloy billet was prepared by gas atomization (GA) and hot isostatic
pressing (HIP), followed by hot extrusion and different heat treatments. Microstructural …

High strength aluminum alloys are widely used but their strength is reduced as nano-
precipitates coarsen rapidly in medium and high temperatures, which greatly limits their …

Abstract Aluminum-lithium (Al–Li) alloys have become an essential material for aircraft skin
in the aerospace industry owing to their high strength and low density. An optimized …

In this study, the T85-treated Al-3.78 Cu-1.17 Li-0.7 Mg-0.32 Ag-0.25 Mn-0.33 Zn-0.12 Zr
alloy thermally exposed at a series of temperatures (100–300° C) for 100 h, 500 h, and 1000 …

The effects of Zr addition on microstructure evolution and mechanical properties of extruded
Al-Cu-Li-Mn alloy were investigated during heat treatment processing. The recrystallization …

A large-scale billet of 2195 Al-Cu-Li alloy was prepared by spray deposition technology. The
hot extrusion, solution treatment, pre-stretching, and aging treatment were performed on the …

Al/B 4 C composites with various volume contents of B 4 C (5%, 10%, 15%, 20%, and 25%)
reinforcing the Al matrix, have been fabricated by vacuum hot press sintering at 680° C, with …

Pre-rolling combined with double aging (DAT8) and interrupted aging (IAT8) were carried
out to improve the mechanical properties of rapidly solidified 2195 Al–Cu–Li alloy. For the …

The addition of Li to Al alloys produces such benefits as a 6% increase of modulus and a 3%
weight reduction upon adding 1 wt% Li, and yet it has led to difficulties for manufacturing …
