Hot workability of Mg-9Y-1MM-0.6Zr alloy

Journal of Rare Earths, 2011
Abstract The behavior evolvement of Mg-9Y-1MM-0.6Zr (WE91) alloy during hot deformation process was discussed. The flow stress behavior of magnesium alloy over the strain rate range of 0.001 to 1 s −1 and the temperature range of 653 to 773 K was studied on a Gleeble-1500D hot simulator under the maximum deformation degree of 60%.

Hot Workability and Constitutive Equations of ZM21 Magnesium Alloy

Key Engineering Materials, 2008
One of the most challenging activities for magnesium industry is to increase productivity by introducing cost-effective processes. While die-cast magnesium alloys are in worldwide use, even in the demanding sector of automotive industry, where cost is the major asset, wrought magnesium alloys still not widely available. The aim of the present study was

Hot workability of V-Ti microalloyed steel for forging

Metallurgical Research & Technology, 2019
The hot compression and the hot tensile experiments were carried out on a Gleeble3800 thermal-mechanical simulator at different deformation conditions. The relationship between the flow stress and Zener-Hollomon parameter was established by the hyperbolic sine function. The hot deformation apparent activation energy is about 371 kJ/mol.

HOT DEFMATION BEHAVIOR AND HOT WORKABILITY OF Mg-Zn-Zr-Ce ALLOY

Acta Metallurgica Sinica, 2012
The hot deformation behavior of the T4-treated Mg-6Zn-0.5Zr-0.5Ce alloy was investigated by compressive test using Gleeble 3800 thermal-simulator in the temperature range of 523—673 Kand strain rate range of 0.001—1.0 s~(-1).The results show that the flow stress is significantly affected by both deformation temperature and strain rate.The flow stress ...

Determination of Hot Workability of 5Cr5MoSiV1 Steel Based on Hot Processing Map

steel research international
The evaluation of the hot workability of 5Cr5MoSiV1 steel with high deformation resistance is crucial for the controllability of the hot forging process. Based on the isothermal compression at deformation temperature of 950–1200 °C and strain rate of 0.01–10 s−1, the flow behavior of 5Cr5MoSiV1 steel is demonstrated.
