Abstract: Hot isostatic pressing (HIP) technology can be used in powder metallurgy to manufacture high-performance components, and in recent years, it has been widely applied in the fields of casting densification, diffusion bonding, and near-net-shape forming. As a green and efficient component preparation technology with simple processes and controllable properties, hot isostatic pressing powder metallurgy (HIP-PM) will be widely used in numerous industrial fields in the future, such as aerospace, nuclear power engineering, electronic information, rail transit, etc. The research progress of HIP-PM technology for duplex stainless steel (DSS) from aspects such as DSS powder preparation, the microstructure and mechanical properties of products are introduced, and corrosion resistance and the application fields and development trends of this technology are summarized.
