Transfer of Ausforming Parameters TO SCALED Forging tools [PDF]
METAL Conference Proeedings, 2021 Forging tools are exposed to cyclically changing thermo-mechanical stress conditions leading to its failure. Damage phenomena on the tool engraving cannot be entirely avoided by hardening the surface, as this leads to a more brittle behaviour and thus to lower ductility of the material, which can intensify the occurring damage effects.

Buildings, 2021 In order to develop the application of the more cost-effective copper-based shape memory alloys (SMAs), rather than nickel–titanium as earthquake energy dissipaters, the influence of ausforming-induced plastic deformation on phase transformations ...

Journal of Materials Research and Technology, 2022 Ausforming treatments are thermomechanical treatments that consist in plastically deforming a fully austenitized steel, usually leading to either a bainitic or a martensitic microstructure.

Journal of Materials Research and Technology, 2020 In this work, the influence of thermomechanical treatments, consisting of a combination of ausforming followed by isothermal holding and cooling to room temperature, on the stability of retained austenite of a carbide-free medium carbon-high silicon ...

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 ...

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).

Effect of Ausforming Temperature on the Microstructure of G91 Steel [PDF]
Metals, 2017 The development of thermomechanical treatments (TMT) has a high potential for improving creep-strength in 9Cr-1Mo ferritic/martensitic steel (ASTM T/P91) to operate at temperatures beyond 600 °C. To maximize the number of nanoscale MX precipitates, an ausforming procedure has been used to increase the number of nucleation sites for precipitation inside
