Microstructure and properties of Cu-0.6Cr alloy after vacuum continuous casting

摘要：

To promote the solution of chromium in copper and the purity of copper-chromium (Cu-Cr) alloy,vacuum continuous casting (VCC) process was employed to fabricate the Cu-Cr alloy required for electrode material.Cu-0.6Cr (containing 0.6％(mass fraction) chromium) alloy bar with a diameter of 12 mm was cast with a constant rate of 250 mm/min.The microstructure,mechanical properties,and physical properties were discussed.After solid solution strengthening and aging treatments,Cu-0.6Cr alloy fabricated by VCC process has higher tensile strength (σ≥314 MPa),elongation rate (δ≥34％),conductivity (≥80.5％ IACS),and hardness (80 HRB) compared to the as-cast alloy.
