Maraging steels : modelling of microstructure, properties and applications /
Maraging steels are high-strength steels combined with good toughness. They are used particularly in aerospace and tooling applications. Maraging refers to the ageing of martensite, a hard microstructure commonly found in steels. Maraging steels: modelling of microstructure, properties and applicati...
