“…Previous work conducted both on C-Mn, 20MnCr5 and Fe-Mn23-C0.6 steels [Puchi-Cabrera et al, 2011;2013a;2013b;2014a;2014b;2015] indicates that this constant in general does not exhibit any significant dependence on T andε. However, in the present case it can be clearly observed that such a constant exhibits a significant dependence on deformation conditions, which should be taken into consideration into the global constitutive formulation.…”

A large number of thermodynamic simulations has been used to design a new Nb-Ti dual stabilized ferritic stainless steel with excellent creep resistance at 1050 °C through an optimal volume fraction of Laves (η) phase stabilized by the alloying elements Nb, Si and Mo. By raising the dissolution temperature of the phase, which also corresponds to the onset of rapid grain growth, the steel will better maintain the mechanical properties at higher service temperature. Laves phase precipitates can also improve creep resistance through precipitation strengthening and grain boundary pinning depending on the dominant creep mechanism. Sag tests at high temperatures for the designed steel showed significantly better results compared to other ferritic stainless steels typically used in high temperature applications at present.

“…Magnesium alloys have been widely used in the transportation field of vehicle and aircraft manufacturing due to their low density, and high specific stiffness and strength [1][2][3][4][5]. In the service environment of these fields, magnesium alloy components including car doors and aircraft shells, often face high-speed impact, and the impact strain rate can even reach more than 10 4 s −1 [6][7][8].…”

An accurate prediction of high speed impact behavior of metals by considering the combined effects of strain, strain rate and temperature is essential for understanding dynamic impact deformation of metals. To understand the effect of strain, strain rate and temperature on the high-speed impact behavior of Mg-1Al-4Y alloy, the dynamic impact compression experiments for Mg-1Al-4Y alloy were carried out by split Hopkinson pressure bar (SHPB). The mechanical properties of Mg-1Al-4Y alloy specimens were studied at different strain rate and temperature. The number of {10-12} extension twins decreases with the strain rate increasing from the electron backscatter diffraction (EBSD) technology, because of the formation of extension twins is suppressed with the strain rate increases, and dislocations become the main mode of dominant deformation. It is also found that the increase of strain rate has a positive effect on the strength of the material. But, the temperatures have a negative impact on the strength of the material. A modified Johnson-cook model has been presented, which shows good predictions with experimental results at different strain rates and temperatures. Especially, the predictions of the Johnson-cook equation are completely consistent with experimental results in small deformation stage.
