文摘

The size of two-phase atomized metal powder is smaller than that of gas atomized under the same atomization condition. Two-phase atomized powders have a more concentrated powder size distribution and more irregular shape. Two-phase atomized powders have larger cooling rate and finer microstructure. Inexpensive atomization medium and simple facility make it a promising low-cost metal powder preparation technology.
