Sintering metal explained Melting iron or nickel? Easy. But tungsten and molybdenum? Their melting points are so high that casting isn’t an option. Instead, they’re shaped using powder metallurgy and sintering, where metal powder is compressed and heated just below melting point. This process bonds the particles without turning them to liquid, preserving the heat resistance and strength of these refractory metals. #science #engineering #facts #metal #sintering #metal #metallurgy | vt.physics

This process is called Powder Metallurgy (PM). It is a technique used to shape metals by compressing their powder into molds and then heat-treating them through sintering to bond the particles and achieve the desired properties. This method is widely used to manufacture engineering components such as gears, self-lubricating bearings, and complex structural parts. | Electronique & Electricité
