| Abstract: | The preparing method of cemented carbide with double- layer grains is introduced. The distinction between the alloy with double-layer grains structure and the alloy with double grains is clear by layers of grains, belinging to the category of homogeneous grain structure. Cemented carbide containing this structure has good complex properties and can meet the special requirements of some products and the practicality is relatively wide. |
