1, to overcome the refractory metal casting process of the difficulties. 1903 manufacturing tungsten wire, to promote the development of powder metallurgy; 1923 powder metallurgy carbide appears as the revolution in mechanical processing.
2, 30 years successfully made porous oil bearing; then powder metallurgy iron-based mechanical parts development, give full play to the powder metallurgy less cutting or even no cutting advantages.
3, to the more advanced new material
s, new technology development. In the 1940s, the emergence of metal ceramics, dispersion strengthening and other materials, from the late sixties to the early seventies, high-speed steel powder, powder superalloys have emerged; the use of powder metallurgy forging and hot isostatic pressure has been able to manufacture high-strength parts.
