The hot tensile test has been used for to examine the influence of such factors as precipitation, composition, inclusions, phase transformation and grain size on hot ductility. Tests were performed mainly in the as-cast condition but also after solution treatment (1330° C) so as to obtain a coarse grain size similar to that found in the continuously ...

Achieving high ductility and strength in magnesium alloy through cryogenic-hot forming
Journal of Magnesium and Alloys, 2023 Magnesium alloys are the lightest structural alloys and have attracted substantial research attention in the past two decades. However, their mechanical properties, including ductility and strength, are limited after forming due to the formation of ...

Effect of Strain Rate on Hot Ductility of a Duplex Stainless Steel
Advances in Materials Science and Engineering, 2019 Duplex stainless steels (DSSs) often have bad hot workability. In this study, specimens of 2205 DSS were hot tensioned over a strain rate range from 0.005 s–1 to 50 s–1 to examine the hot ductility.

The hot ductility of steels [PDF]
Hot tensile tests have been performed on a variety of plain carbon and micro-alloyed steels, in order to determine the influence of such factors as phase transformation, grain size and precipitation on hot ductility. The γ-∝ phase transformation has been shown to produce a significant ductility trough in the high temperature tensile behaviour of plain ...

The role of ductility in hot working [PDF]
, 1967 Strength and ductility are the important characteristics which govern the hot working properties of a material. This paper describes test methods for measuring hot workability and then discusses deformation and fracture mechanisms in hot working. Particular emphasis is laid on the correlation of strength and ductility data in simple materials in terms ...
