Deformation characteristics of Al-4043 alloy

Serrated flow and work hardening characteristics of Al-5356 alloy

“…Experimental sets of stress-strain relations were performed at different temperatures for the alloy wires having different grain diameter by using a tensile testing machine described elsewhere [21]. The deformation temperature studied 303, 323, 348 and 373 K. The wires were heated while they were clamped in the tensile testing machine.…”

“…The energy activating the deformation process may be evaluated from the variation of the yield stress y , as related to the deformation temperature T w , through the kinetic rate equation [21]: Fig. 8.…”

The effect of undercooling on the microstructure and tensile properties of hypoeutectic Sn–6.5Zn–xCu Pb-free solders

“…Before testing, the specimens were annealed at 120°C for 45 min to reduce the residual stress induced during sample preparation. Then, tensile properties were characterized using a computerized tensile testing machine described elsewhere [15] at temperature range of 25-110°C. The tensile tests also were carried out at various strain rates ranging from 10 À5 to 10 À3 s À1 and constant temperature of 25°C.…”

Constitutive equation and microstructure evaluation of an extruded aluminum alloy

“…This type of flow curve is referred as dynamic recovery type of flow curve. Dynamic recovery is the only softening mechanism occurring under this process condition [4,5]. In case of 673 and 773 K the curve exhibits a slight dip in flow-stress value after reaching the peak stress.…”
