调和组织是以粉末颗粒表层的超细晶粒为壳层和粉末颗粒内部的粗晶为芯部,超细晶以连续三维网络包围粗晶的一种组织结构,藉以达到强化材料、改善延展性的双重目的。列举Ti合金、不锈钢、高速钢/低碳钢、钴基合金、纯Cu等为案例,描述其各自的制备技术及力学性能,并从起始粉末、粉末表层强力塑变、热致密化成形3方面,就这些制备调和组织的技术核心作了述评。
Reconciliation is the organization of ultrafine grains on the surface of the powder particles as the shell and the coarse grains inside the powder particles as the core, ultrafine grain to a continuous three-dimensional network of coarse grains surrounded by a structure, in order to achieve enhanced materials to improve ductility The dual purpose. The Ti alloy, stainless steel, high-speed steel / mild steel, cobalt-based alloy and pure Cu are cited as examples to describe the preparation technology and mechanical properties of the alloy. The invention is characterized by intensive plastic deformation and thermal densification of starting powder and powder surface 3 In terms of the technical core of these preparations for reconciliation, they made a commentary.
