摘要

Cu reticulated mesh and stochastic open cellular foams were fabricated by additive manufacturing using electron beam melting. Fabricated densities ranged from 0.73 g/cm~3 to 6.67 g/cm~3. The precursor Cu pow der contained Cu_2O precipitates and the fabricated components contained arrays of CU_2O precipitates and interconnected dislocation microstructures having average spacings of ~2 μm, which provide hard ness values ~75% above commercial Cu products. Plots of stiffness (Young's modulus) versus density and relative stiffness versus relative density were in very close agreement with the Gibson-Ashby model for open cellular foams. These open cellular structure components exhibit considerable potential for novel, complex, multi-functional electrical and thermal management systems, especially complex, monolithic heat exchange devices.
