; Abstract: Al-8.5Fe-1.3V-1.7Si alloy was prepared by spray deposition and hot extrusion. The high temperature plastic deformation... simulator. The mechanism of the high temperature plastic deformation of the alloys was studied by TEM associated with the analysis of Rosler-Artz physical constitutive relationship based on the model......
, and the orientation dependence of the plastic deformation behavior was examined at room temperature (RT). At 0?-orientation, temperature dependence of the yield stress was also examined.... The controlling mechanisms of the plastic deformation behavior at high temperatures above 300 ℃, probably affected by the operation of non-basal slip, grain boundary sliding etc, are now under survey......

Key words: 7075/6009 composite ingot; plastic deformation temperature; microstructure; mechanical properties  ... of d 65 mm×300 mm for plastic deformation were cut from 7075/6009 composite ingot, which was prepared by DSPCC processing as introduced in our previous work[14]. The ingots were heated at temperature......
of 373 K and a high strain rate, work hardening mechanism plays a main role on the behavior of plastic deformation. At the intermediate temperature of 423 K, the mechanism includes both work hardening... during the plastic deformation process at different temperatures and strain rates. The dynamic recrystallization starts when the temperature is over 473 K and the DRX grain size after hot deformation......
