Abstract
Section titled āAbstractāCuCrZr alloy has excellent conductivity, thermal conductivity, friction reduction and abrasion resistance, which can satisfy in different fields. Copper alloy porous structure is a new multifunctional structure with both structural and functional properties. Selective laser melting (SLM) technology has certain advantages for the preparation of periodic porous structures with triply periodic minimal surfaces (TPMS). Under the background of SLM technique, the quasi-static compression properties of Diamond and Gyroid porous structures were studied. The whole deformation of structures was captured by digital camera, and the failure mechanism was analyzed by finite element software. The effects of different heat treatments on the microstructure and mechanical properties of the CuCrZr were studied by scanning electron microscopy and compression tests. The microstructure morphologies show that the number of curved grains decreases and the grains become more regular after heat treatment. Heat treatment can optimize the mechanical properties and energy absorption capacity of the material, which is most obvious at 500 Ā°C. These results indicate that specific heat treatment can improve the stability and predictability of the CuCrZr porous structure.
