Maraging steels are high-strength steels combined with good toughness. They are used particularly in aerospace and tooling applications. Maraging refers tothe ageing of martensite, a hard microstructure commonly found in steels. Maraging steels: modelling of microstructure, properties and applications covers the following topics: Introduction to maraging steels; Microstructure of maraging steels; Mechanical properties of maraging steels; Thermodynamic calculations for quantifying the phase fraction and element partition in maraging systems and precipitation hardening steels; Quantification of phase transformationkinetics in maraging steels; Quantification of age hardening in maraging steels; Maraging steels and overageing; Precipitation hardening stainless steel; Applications of artificial neural network on modelling maraging steel properties. With its distinguished authors, Maraging steels: modelling of microstructure, properties and applications will be a standard reference for industry andresearchers concerned with maraging steels and modelling as well as users of maraging steels in the aerospace and tooling sectors. The book includes both conventional maraging steels and precipitation hardened (PH) stainless steels.
