Influence of Trace Elements on Hot Ductility of an Ultra High Purity Invar Alloy

, 1995
Like steels, austenitic INVAR alloys Fe-Ni 36 % show a large ductility trough between 500°C and 1100°C. To understand hot brittleness mechanisms and especially trace element effects, synthetic alloys were prepared using ultra-high purity iron and nickel ...

The influence of particle types of metal reinforcement on the microstructure and properties of magnesium-based composites

Journal of Materials Research and Technology
Magnesium-based composites reinforced with metallic particles are highly valued for their enhanced modulus and balanced strength-ductility. This study systematically investigates the effects of three typical metallic particles (Ti, Fe, Ni) on the ...

Further analysis of the relationship between precipitate formation and a loss of hot ductility in two microalloyed steels

, 2022
Several technical alloys experience an isolated area of lower deformability at elevated temperatures, which usually falls between 600 °C and 1000 °C for steels. This second ductility minimum can lead to severe problems.

Exceptional fatigue life and ductility of new liquid healing hot isostatic pressing especially tailored for additive manufactured aluminum alloys

, 2023
Porosity and hot cracking still hinder the introduction of new additive manufactured alloys on the market, which requires high reliability. Hot Isostatic Pressing (HIP) is thus commonly applied to close these defects.
