It has been found that during the spark plasma sintering process, under the condition of large current, short sintering time and lower sintering temperature, the metastable icosahedron quasicrystal phase in primary powder particles is kept. And the strong discharge plasma among particles can decompose or break the oxide film on the primary powder's surface, resulting in the increment of their combination strength. So the as-prepared bulk alloy possesses high density and ultra-high strength.

The research results show as follows. As plastic deformation increases, the Young's modulus of material continuously changes. This variation law is able to be described using a piecewise linear function .Hardening model and whether the variation is considered or not make great effet on springback prediction. It is proved that the springback prediction result which adopts the elastic-plastic constitutive model based on INLK hardening model and the variation of Young's modulus is considered, is more close to experimental result. After the sheet metal undergoes multiple bending, the corner radius and bending height also affect springback greatly.But the effect trend is different. At the same time, the reliability of springback research using numerical simulation is proved.

The results show that the microstructures of these three kinds of coating are different from those of the matrix (20 steel). The wear resistance of the flame spray coating is 4. 9 times that of the matrix. This is caused by the existance of hard noncrystal microparticals. The wear resistance of the coating by flame spray welding is 6. 3 times that of the matrix. The reason is that the fine crystal grains can be formed and the solution strengthening, dispersion hardening can be induced by these alloy elements. The resistance of the laser remelt coating is 8. 8 times that of the matrix. This is due to the solution strengthening, dispersion hardening and the existence of very hard dendritic crystal, eutectic and martensite in the microstructure.
作者指出,喷涂层由于层内有一定数量高硬度的合金非晶质点存在,其耐磨性是钢基体的4.9倍;喷熔层内合金晶化产生的晶粒细小,合金元素能起固溶强化作用,也能生成化合物产生弥散硬化作用,故此耐磨性是钢基体的6.3倍;激光涂敷层除所含合金元素产生的固溶强化和弥散硬化作用外,表层组织为高硬度的枝晶+共晶和马氏体,故其耐磨性是钢基体的8.8倍。
