In Cu-Ni-Si, cobalt accelerates precipitation but coarsens it and degrades properties — more isn't always better. Sweet spot: lower-Co alloy, 500 °C/2 h, 40% cold work — 250 HV with 43% IACS, from orthorhombic (Ni,Co)2Si precipitates with defined orientation relationships to the copper matrix. Based on the paper: Co Effects on Cu-Ni-Si Alloys Microstructure and Physical Properties; Z. Zhao, Y. Zhang, B. Tian, Y. Jia, Y. Liu, K. Song, A.A. Volinsky; Journal of Alloys and Compounds, 2019, Vol. 797, pp. 1327–1337. Hosts Elena and Marcus. AI-generated voices.
