Hot Workability of High Strength 6060 Alloy
Materials Science Forum, 2000The alloy with 0.4% Mg and 0.5% Si was torsion tested in the range 0.1 to 10 s-1 and 300 to 500°C with exhibition of excellent ductility. The hot strength was shown to be low compared to other 6000 series alloys and to have little tendency to dynamic precipitation. The hyperbolic sine constitutive equation was optimized with a stress multiplier of 0.03

A model for the evaluation of hot workability of metallic materials
Journal of Materials Processing Technology, 1990Abstract Hot workability is presented from the systems point of view. Based on a polar reciprocity relationship between the stress and strain rate spaces, a measure of hot workability called hardening power index is defined. Deformation processing maps of this parameter are plotted for a titanium alloy IMI685 (Ti-6Al-5Zr-0.2Mo-0.1Si) using flow data ...

Hot workability and extrusion modelling of magnesium alloys
Zeitschrift für Metallkunde, 2005Abstract The hot working of commercial Mg alloys differs from creep in so far that twinning is much more prevalent in the early stages and dynamic recrystallization (DRX) becomes extensive above 400 °C. Subgrains form mainly near the grain boundaries and have similar dependence on stress; they were larger in hot working tests because of the much higher

Hot-worked microstructure and hot workability of cold-work tool steels
Materials Characterization, 2018Abstract The hot workability of two cold-work tool steels were evaluated and compared. A D2 and an advanced alloy based on 8% Cr steels (TDx) were deformed at high temperatures between 900 and 1100 °C with strain rates 0.001–10 s− 1 via hot compression test.

(D) Effect of oxygen on hot workability of steel
International Metals Reviews, 1977AbstractThe detrimental effects of non-metallic inclusions on the ductility of steel at hot-working temperatures are well known. Often, relatively small variations in inclusion contents or distributions may determine whether a steel can be successfully worked without cracking.

Determination of Hot Workability of 5Cr5MoSiV1 Steel Based on Hot Processing Map
steel research internationalThe 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.

Hot Workability of Alloy WE43 Examined Using Hot Torsion Testing
2011While rare earth additions can impart a variety of property improvements in magnesium alloys, they can also limit the processing parameter window inside which the alloys may be successfully wrought in commercial production routes such as extrusion and rolling.
