โœฆ Synopsis

The hot deformation behavior and microstructure evolution of extruded ZE41A magnesium alloy has been studied using the processing map. The compression tests were conducted in the temperature range of 250-450 ยฐC and the strain rate range of 0.001-1.0 s ร€1 to establish the processing map. The dynamic recrystallization (DRX) and instability zones were identified and validated through micrographs. The observations were performed in order to describe the behavior of the material under hot forming operation in terms of material damage and micro-structural modification.

The hot deformation behavior of electrolytic touch pitch (ETP) copper has been studied in the temperature range 300-950 โ€ข C and strain rate range 0.001-100 s -1 using isothermal hot compression tests. Processing maps are developed at different plastic strains with a view to characterize the dynamics
