Traditional powder metallurgy technology is mainly powder molding and ordinary sintering, while there are more and more types of modern powder metallurgy technology, including powder thermal isostatic pressure, selective laser sintering, microwave sintering, explosion consolidation, atmospheric pressure solidification, self-spreading sintering and powder injection molding technology, etc.
For example, ultra-fine powder preparation technology, rapid condensation, mechanical alloying, jet deposition, STAMP technology, rapid omni-way pressing, etc. Moreover, these processes and technologies have common characteristics, which are all developing in the direction of advanced, refined and industrial scale.
After decades of development, modern powder metallurgy and early powder metallurgy have undergone great changes, including the progress of technology and process, the emergence and application of materials, and the improvement and perfection of equipment, etc.
As an indispensable part of powder metallurgy, materials are also constantly being updated. Nowadays, large-block nanomaterials, powdered high-temperature alloys, powdered high-speed steel, powdered stainless steel, powdered alloy steel, fast-solidified powdered aluminum alloy, fast-solidified magnesium alloy, fast-solidified titanium alloy and special ceramics, etc. are widely used, all of which show the characteristics of full density and high performance.
