Multiphase Ausformed Austempered Ductile Iron [PDF]
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 ...

Transfer of Ausforming Parameters TO SCALED Forging tools [PDF]
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.

Microstructure Refinement by Low-Temperature Ausforming in an Fe-Based Metastable High-Entropy Alloy
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 ...

Effect of Ausforming on Retained Austenite After Continuous Cooling Transformation in a Medium-Carbon High Strength Steel [PDF]
The effects of deformation on transformation kinetics during continuous cooling and microstructure evolution of a medium carbon high strength steel were investigated by metallographic method, dilatometry and X-ray diffraction etc.

Creep strength boosted by a high-density of stable nanoprecipitates in high-chromium steels
There is a need worldwide to develop materials for advanced power plants with steam temperatures of 700°C and above that will achieve long-term creep-rupture strength and low CO2 emissions.

Ausforming treatments are thermomechanical treatments that consist in plastically deforming a fully austenitized steel, usually leading to either a bainitic or a martensitic microstructure.

Tempforming as an Advanced Processing Method for Carbon Steels
The microstructural mechanisms providing delamination toughness in high-strength low-alloyed steels are briefly reviewed. Thermo-mechanical processing methods improving both the strength and impact toughness are described, with a close relation to the ...
