The high temperature flow behavior modeling of AZ81 magnesium alloy considering strain effects

Constitutive model for elevated temperature flow stress of AZ41M magnesium alloy considering the compensation of strain

“…However, only the effects of strain rate and temperature are considered in lots of the previous investigations, the effect of strain is usually ignored. Considering the influence of strain comprehensively, a modified constitutive model has been utilized by lots of researchers to predict the high temperature deformation behaviors in AZ81 [17], AZ61 [18] and AZ31B [19]. Despite of the attention paid to the research of Mg-Al-Zn alloy system which has attracted a great demand because of its good weldability and excellent corrosion resistance, research reports focusing on the strain dependent constitutive analysis of AZ41M magnesium alloy are still unavailable.…”

Carbon nanotube addition to concentrated magnesium alloy AZ81: Enhanced ductility with occasional significant increase in strength

“…The inclusion of CNT into metal based matrices holds much scientific and technological promise regarding significant mechanical property improvement. Magnesium alloys are available as lightweight and energy saving metallic matrices [11,12]. The AZ (Aluminium-Zinc) series of magnesium alloys are characterized by: (a) low cost, (b) ease of handling, (c) good strength and ductility and (d) resistance to atmospheric corrosion [13].…”

Constitutive equation and microstructure evaluation of an extruded aluminum alloy

“…It can be observed that the strain value has significant impact on material constants. Thus to predict the flow stress accurately, the influence of the strain was incorporated into the constitutive equation by assuming that the activation energy Q and other material constants were polynomial functions of the strain [16,17].…”
