Maraging steels are widely used in industrial applications due to their strength, toughness, formability, stress corrosion resistance, fatigue strength and weldability properties. The use of powder metallurgy has attracted attention in recent years compared to traditional production methods for producing maraging steels. In this study, maraging steel powders were consolidated by the pressure-assisted sintering method, which is a powder metallurgical process. With computational materials engineering applications, process parameters are determined with reliable thermodynamic data. The sintering temperatures of the maraging steel for the pressure-assisted sintering process were analyzed based on the chemical composition data with computational materials engineering applications. The densification process was conducted at different sintering times (15, 30 and 45 min) at the determined sintering temperature (950 °C). The productions were carried out in a vacuum environment of 10-4 mbar and under a pressure of 45 MPa. The final densities of the obtained samples were measured according to the Archimedes principle. As a result of the increase in sintering time, the relative density measurements increased from 88% to 92%. In addition, the effect of sintering time on the microstructure was investigated by microstructural characterization studies. This study aims to reveal the contribution of computational materials engineering applications to the determination of process parameters in powder metallurgical production methods.
