The annealing kinetics of cold-rolled AA5182 and AA5657 aluminum alloy sheets have been investigated compared. microstructures a series partially recrystallized samples are characterized by electron back scattered diffraction key stereological parameters including volume fraction recrystallized, interfacial areas contiguity determined. overall recrystallization as well the nucleation growth rat...

The static recrystallization/grain growth kinetics of the AZ31 (Mg-3Al-1Zn, wt%) alloy were investigated employing Vickers microhardness and electron backscatter diffraction (EBSD) measurements. was subject to a hot-rolling for 70% thickness reduction then annealed at various temperatures (150°C, 250°C, 350°C) from 5 min 24 h. First, recrystallization analysed by means Johnson-Mehl-Avrami-Kolmo...

The recrystallization and grain growth behaviour of IN718 alloy additively manufactured by laser powder bed fusion (L-PBF) is presented herein. effects three different temperatures (1050, 1150 1250 °C) holding times (15, 45 90 min) were investigated. texture evolution the samples was recorded via electron backscatter diffraction (EBSD). as-built sample composed bowl-shaped melt pools, a chessbo...

This study addresses the crystallization and multiple melting behavior of a new high temperature semicrystalline polyimide, which is based on an ether diamine (TPER or 1,3 (4) APB) and BTDA dianhydride, both of which are commercially available. It also uses phthalic anhydride to endcap the chains thus improving thermal stability. The polyimide displays a Tg at ca. 230°C and two prominent meltin...

20Mn5 steel is widely used in the manufacture of heavy hydro-generator shaft forging due to its strength, toughness, and wear resistance. However, the hot deformation and recrystallization behaviors of 20Mn5 steel compressed under a high temperature were not studied. For this article, hot compression experiments under temperatures of 850-1200 °C and strain rates of 0.01 s-1-1 s-1 were conducted...
