Following the development of hot isostatic pressing (HIP) with integrated rapid cooling technology, it is now possible to combine consolidation of encapsulated powder and subsequent heat treatment in a single step. In this study, the influences of pressure and cooling rate on the microstructural evolution of martensitic and duplex steels during the entire HIP process with rapid cooling are investigated. Besides the microscopic investigation of the microstructure, a material model for finite element (FE-) simulations was developed to numerically correlate the understanding based on experiments and to predict the final shape of the HIP component. This FE-simulation was additionally employed in the capsule design to achieve net-shape production of the components with complex geometries. The agreement between the experimental and simulated results validated the method to be able to ensure a near-net-shape product and to monitor microstructural development during HIP and rapid cooling.
