Experimental Research on Laser Clad Forming and Its Micro-Crackles Controlling Sun K1,ZHOU K G C1,SONG J L1,DENG Q L1 (1.Shanghai Jiaotong University, Shanghai 200030, P. R. China) 摘要:Laser clad forming (LCF)is a new kind of rapid manufacturing technology. It can directly manufacture compacted metal components and has many advantages. Some experimentalresearches have been carried out......
metallurgy, in which the diamond particles were pre-coated by magnetic sputtering with copper alloy containing a small amount of carbide forming elements (including B, Cr, Ti, and Si). The influence of the carbide forming element additives on the microstructure and thermal conductivity of diamond composites was investigated. It is found that the composites fabricated with Cu-0.5B coated diamond......
Trans. Nonferrous Met. Soc. China 22(2012) 590-595 Effect of minor Fe addition on glass forming ability and mechanical properties of Zr55Al10Ni5Cu30 bulk metallic glass LIU Guang-qiao1, KOU... forming ability(GFA) and mechanical properties of Zr55Al10Ni5Cu30 bulk metallic glass (BMG) were investigated. The results show that the addition of an appropriate amount (less than 3%, mole fraction......
the mentioned limit, rupture is considered in the blank during the forming process. Therefore, a rigid punch with deep central zone is prepared as shown in Fig. 15, and some blanks are compressed... is enhanced, too. On the other hand, depending on blank geometry and material type, there is an upper limit for angle γ and forming process on rigid punches with angle γ less than that at which the mentioned......
