State Key Laboratory of Materials Processing and Die... properties and anodic oxidation effect. Laser engineered net shaping technology has unique advantages in the integrated forming of high-performance large aircraft structural parts. The manufacturing......
. The results show that the optimal mass fraction of the CuP in the powder system is 15%. Key words: copper-based metal powder; additive; selective laser sintering; liquid phase sintering liquid volume fraction on direct laser sintering of metallic powder[J]. Mater Sci Eng A, 2004, 371(1-2): 170-177. [16]Barin I, Platzki G......
. The liquid WC comes into melt pool and reacts with liquid Fe. Just because of full reaction between particles and substrate, the pre-feeding mode was widely used in laser cladding. On the contrary, under... and forms block primary. On the other hand, the surfaces of WC particles will melt when they are heated by laser beam. After injected into the laser pool, liquid WC droplets which break away from WC......
to the limited liquid phase, showing typical sintering forming characteristics. After polishing, the microstructure of laser sintered Fe-Zn parts was captured by OM, as shown in Figure 5(b... the laser parameters. During sintering, a small amount of liquid phase formed and wetted the particles, thus promoting the rearrangement of particles and finally realizing the densification behavior [27......
composite powder with fine grains is used[13, 16]. With a further action of laser irradiation, the Cu matrix also melts to form liquid phase. Consequently, a molten pool containing both liquid phase(Co and Cu... Variation of microhardness across cross-section of laser sintered sample 4 Conclusions 1) Through the liquid phase sintering mechanism, the WC-10%Co particulate reinforced Cu matrix composite material......
energy density laser beam was focused on the current powder layer, the powders in the laser affected region could be completely melted to liquid and form a melt pool. The already solidified matrix...
