specimens after deformation at 1000 °C with different initial strain rates and their engineering stress-strain curves are shown in Fig. 4. At 1000 °C, by decreasing the initial strain rate from 1... the engineering stress-strain curves, it is found that the stress decreases obviously after it reaches the ultimate strength, indicating that the strain softening is dominant afterwards. Fig. 4 Engineering......
for reducing residual stress on the workpiece surface. MORI et al [57] developed a hot shear spinning process for a cast aluminum alloy (7.36%Si, 0.18%Fe, 0.05%Cu, 0.02%Mn, 0.57%Mg, 0.01%Zn, 0.06%Ti... the thickness is only 4 mm [72]. Fig. 2 Schematic picture of flame heating spinning [45] Another portable heating method consists of heating before spinning in a furnace or using high frequency......
, as shown in Fig. 4. XRD profiles revealed peaks corresponding to only α and β phases in the as-cast TNZV alloy. The microstructure of an investigated TNZV alloy depends essentially upon both... within pre-existing β phase is seen in the furnace-cooled (FC) samples solution-treated at 650 °C (Figs. 5(a) and 6(a)).
