Processing maps and microstructural evolution of isothermal compressed Al–Cu–Li alloy

Effects of initial aging time on processing map and microstructures of a nickel-based superalloy

“…The optimum hot working parameters for Al6063/0.75Al 2 O 3 /0.75Y 2 O 3 nano-composite were identified, and the flow instability characteristics were validated by processing maps and micrographs [37]. Additionally, the processing maps were developed for some other important alloys or composites, such as Al-Cu-Li alloy [38], Al-Cu-Mg alloys microalloyed with Sn [39], DC cast Al-15% Si alloy [40], SiC particles reinforced metal matrix composites [41], as-cast AISI M2 high-speed steel containing Mischmetal [42], Aluminum-5 wt% B4C Composite [43], near-α titanium alloy IMI834 [44], extruded Mg-12Li-1Zn BCC alloy [45], as-cast Ti-43Al-4Nb-1.4W-0.6B alloy [46], (SiCpþMg2B2O5w)/6061 Al hybrid and SiCp/6061 Al composites [47], Al-Cu-Li-Sc-Zr alloy [48], 7005 aluminum alloy [49], and 800H alloy [50].…”

Correlation of microstructure and mechanical properties in friction stir welded 2198-T8 Al–Li alloy

“…The third generation of damage-tolerant Al-Li alloys has been investigated these years, with special focus on the precipitation evolution and the mechanical properties. For instance, 2198 alloy relies mostly on the precipitation of the T1 (Al 2 CuLi) phase to achieve its excellent mechanical properties [6,7]. It is also reported that Al-Li 2198-T8 (artificially peak aged) alloy sheet contains a high density of T1 phase with high aspect ratio (approximately thickness of 1.3 nm and diameter of 50 nm) [8].…”

A Review on Superplastic Formation Behavior of Al Alloys

“…Xinming Zhang et al [70][71][72][73][74][75][76] did superplastic investigation on 2A97 Al-Li alloy at the temperature range of 480°C-490°C and strain rates of 0.001-0.0025/s. e results indicated that the alloy exhibited promising elongation, ranging from 600% to 850%, and the highest elongation of 850% was achieved at 490°C and the initial strain rate of 0.002/s.…”
