Alloy steels those that are added with alloying elements to achieve certain material properties. Alloying elements are added in lower quantities to increase hardenability or strength, and in larger ...

Alloy steel is steel alloyed with various elements in total amounts between 1 and 50% by weight to improve its mechanical properties including wear resistance, toughness, hardness and strength. It is ...

High-entropy alloys (HEAs) are promising materials for catalysis and energy storage, and at the same time they are extremely hard, heat resistant and demonstrate great variability in their magnetic ...

Precipitation-hardenable (PH) stainless steels are turning up in more and more aerospace applications because they can be age hardened, sometimes after being cold worked, to various strength levels ...
