Analysis on the Key Parameters to Predict Flow Stress during Ausforming in a High-Carbon Bainitic Steel [PDF]
Metals, 2023 Since flow stress is an important parameter in the processing and application of metallic materials, it is necessary to trace the flow stress during austenite deformation. Thermal compression deformation of austenite in a high-strength bainitic steel was

Microstructure Refinement by Low-Temperature Ausforming in an Fe-Based Metastable High-Entropy Alloy [PDF]
Metals, 2021 The effects of ausforming in an Fe30Mn10Cr10Co high-entropy alloy on the microstructure, hardness, and plastic anisotropy were investigated. The alloy showed a dual-phase microstructure consisting of face-centered cubic (FCC) austenite and hexagonal ...

Ausforming and Marforming of a Cu-Zn26.3-Al3.9 Shape Memory Alloy [PDF]
Le Journal de Physique IV, 1997 A copper-based shape memory alloy with Ms below ambient temperature is investigated in four different conditions: 1) As betatized. 2) Ausformed at 800 C and at 780 C, subsequently quenched. 3) Marformed by different amounts of true plastic deformation at temperatures below Mf. 4) Mechanically cycled (ausformed and as betatized state).

Multiphase Ausformed Austempered Ductile Iron [PDF]
Archives of Metallurgy and Materials, 2017 Ductile iron was subjected to a total true strain (φt) of 0.3 either by applying φt in the austenite region or by apportioning it through applying a true strain of 0.2 in the austenite region before quenching to austempering temperature (TA) of 375°C ...
