The Importance of Green Strength in Powder Metallurgy Process
As compacted metal powders coalesce, and this is before the sintering process, the compressed material is imbued with what’s known as “Green strength.” Remember, the metal particles haven’t bonded yet, haven’t fused with each other. However, the unsintered product is mechanically tough enough to handle machining operations. Those supplementary stages won’t damage the compacted workpiece, […]
What are the Major Stages of the Sintering Process?
The sintering process occurs after a mass of atomized powder has been compacted. Further back, the powder metal has been mixed and blended with a liquid phase. Oils and bonding additives have spread uniformly throughout the mix. A closed die now imparts the amorphous mass its dimensional profile. Now, leaving those profile-forming stages behind, we […]
