Near Net Shape Manufacturing using Metal Powders

Webinars 19 October 2022

Near Net Shape Manufacturing using Metal Powders

Manufacturing of high performance and complex geometry parts with a reduced buy-to-fly ratio is one of the key challenges industries are currently facing.

Traditional manufacturing processes such as casting-forging and machining do not offer the required flexibility in design and manufacture of high value engineering parts efficiently and without material wastage. Moreover, engineering materials processed through traditional manufacturing processes usually possess a range of defects such as porosity, elemental segregation, anisotropy in microstructure and materials’ properties, etc.

Near net shape powder metallurgy hot isostatic pressing (NNS PM HIP) represents a valid alternative which can guarantee the manufacture of complex parts with isotropic materials’ properties.

This webinar will aim to provide some practical examples on the design strategies used to manufacture near net shape parts through NNS PM HIP technique. Furthermore, to prove the industrial viability of the process, the microstructural and mechanical properties of the manufactured parts will also be presented. PM-based additive manufacturing processes will also be briefly presented.

He is a member of ASME Standards AMS additive manufacturing metal committee. He is also currently supervising 7 PhDs mainly research related to PM based advanced manufacturing technologies.

Alessandro Sergi - Project Leader, Thermal Processing Technologies

Alessandro Sergi

Project Leader, Thermal Processing Technologies

Alessandro Sergi started his role as Project Leader at TWI in September 2021. He is currently completing his PhD on Powder Metallurgy Hot Isostatic Pressing of high temperature materials (PM) at TWI Ltd and the University of Birmingham, with particular focus on the influence of powder characteristics on microstructure and mechanical properties of as-HIPed parts.

Before his PhD, Alessandro obtained a BSc and MSc degree in Mechanical Engineering at the University of Calabria (Italy).

During his career, he has developed expertise in powder metallurgy, hot isostatic pressing, metallurgy of Ni-based superalloys and refractory metals, with particular focus on how powder characteristics affect the final properties in powder-related manufacturing processes.
