AI Technical Summary
Existing technologies struggle to fabricate high-density CuCrZr alloy parts using laser additive manufacturing. As the nano-precipitates gradually coarsen, the alloy's mechanical properties decline, becoming a bottleneck restricting the manufacturing of high-end equipment.
Rare earth oxide dispersion-strengthened CuCrZr alloy powder is used to prepare rare earth oxide dispersion-strengthened CuCrZr alloy parts by electron beam selective melting technology. The specific steps include mixing and ball milling, drying, layer scanning and electron beam selective melting, and control parameters such as ball milling time, scanning path and gas protection.
It improves the density and mechanical properties of CuCrZr alloy parts, meeting the requirements for use in high temperature and high pressure environments, especially exhibiting excellent tensile strength and elongation after fracture at 600℃.
