Abstract

Advanced alloy production with high mechanical properties and corrosion resistance is a challenging task, sometimes technical and non-viable by conventional metallurgy process due to the need for special temperatures, inert atmospheres or requirements related to the high plastic deformation process. These alloys, crucial for aerospace, energy production and biomedical industries, demand continuous innovation in metallurgical processes and manufacturing technologies. Traditional casting methods face issues like phase segregation and high costs due to the required high temperatures for fusing refractory elements. Powder metallurgy, which presents advanced solid-state production, is an alternative route to achieve advanced alloys. Advanced secondary powder metallurgy processes can eliminate residual porosity and achieve submicron or nanoscale grain sizes, enhancing mechanical alloy properties. Secondary treatments, like hot isostatic pressing, plastic deformation and heat treatments, are necessary to optimize these alloys for high-performance applications. These processes help match or surpass the properties of traditionally manufactured alloys. The development of advanced manufacturing processes is driven by the need for materials with tailored properties for specific applications. These processes can reduce production costs and improve the properties of casting alloys, allowing for industrial-scale production that meets the severe demands of various industrial sectors.
