Hot workability of nanocrystalline AZ91 magnesium alloy [PDF]
Journal of Alloys and Compounds, 2014 This study examined the hot deformation behavior and workability characteristics of nanocrystalline AZ91 Mg alloy by performing hot compression tests with a Gleeble-3800 machine. To this end, a nanocrystalline alloy powder with a crystallite size of 25 nm was synthesized via mechanical milling of a pre-alloyed AZ91 Mg alloy powder for 14 h.

Hot deformation behavior of micro-alloyed steel using processing maps developed with different constitutive equations [PDF]
Journal of Mining and Metallurgy. Section B: Metallurgy, 2022 The hot workability of microalloyed steel was studied in the deformation temperature range of 850–1200ºC and strain rate of 0.001-100s-1. The constitutive relation of flow stress with temperature, strain rate and strain was established to construct ...

Hot Workability Investigation of an Fe-Al-Ta Alloy Using Deformation Processing Maps
Metals, 2023 Fe-Al-Ta alloys are expected to replace high-alloyed steels in steam turbine blades. However, the mechanical properties of the forged blades are still not optimal due to limited grain refinement during hot forging and the coarse-grained microstructure ...
