Mechanical alloying method is to select a certain proportion of tungsten alloy initial powder and metal ball into the ball mill. Under the action of different speed of metal ball, the powder undergoes cold welding and multiple deformations, and finally gets the composite powder with fine structure and uniform composition. 3. Forming
There is provided a ball mill having a milling chamber into which metal powder is fed. The ball mill is also provided with milling means for milling metal powder into fine metal powder having a particle size less than a predetermined size. When the ball mill operates, a quantity of heat (Q 0 ) is generated in the milling chamber. The milling chamber is cooled by liquid cooling means .

Metal mixes. Mechanical alloying is akin to metal powder processing, where metals may be mixed to produce superalloys. Mechanical alloying occurs in three steps. First, the alloy materials are combined in a ball mill and ground to a fine powder. A hot isostatic pressing (HIP) process is then applied to simultaneously compress and sinter the powder.
