Web29 Apr 2024 · Cracking of green parts in powder metallurgy (PM) is a big concern in PM industry. Detection of cracks in green parts before sintering can prevent recycling of already sintered parts or production of defective ones. As opposed to sintered parts, where the presence of cracks is well revealed by impact spectroscopy, it is challenging for green parts. Web18 Jul 2024 · The crystallographic structure affects the mechanical characteristics of both the metal powder and the finished component. As a result, the powder manufacturing process and the metal powder compacting parts manufacturing procedures must be designed to generate materials with the appropriate phase composition, grain size, and …
