Forging porosity
WebJan 15, 2024 · Forging and casting are two very different manufacturing methods. When something is cast, the material is heated above its melting temperature and poured into a mold where it solidifies. ... As an engineer, I have always known that forgings normally have less surface porosity, finer grain structure, higher tensile strength, better fatigue life ... WebConventional powder metallurgy (P/M), metal injection molding (MIM) and powder forging (P/F) are the three most commonly specified powder metallurgy processes. The processes are used for essentially the same alloys groups as forging. MIM is currently limited to very small components, up to approximately 100 gm (3.5 oz) of complex …
