Tensile Properties and Bending Formability of Drawn Magnesium Alloy Pipes

Hall-Petch parameters in tension and compression in cast Mg–2Zn alloys

“…In tension, where k was measured at higher strains, k approaches a constant value of 0.45 MPa m 1/2 at these large strains. This value is significantly higher than those of between 0.11 and 0.32 MPa m 1/2 obtained from pure Mg and alloys grain-refined using hot working and recrystallisation [3][4][5][6][7][8][9][10]19], as well as higher that those of 0.25 and 0.39 MPa m 1/2 from pure Mg grain refined with Zr [15]. The low value of σ 0 is interesting, suggesting as it does, only a small hardening effect of the Zn and Zr additions (see Section 4, below).…”

“…Much of the early work on magnesium alloys used methods that relied on hot working and annealing [3][4][5][6][7][8][9]. The technique is likely to result in a textured material, and this is especially so for magnesium with its limited slip systems.…”
