Improvement in Strength and Ductility of Asymmetric-Cryorolled Copper Sheets Under Low-Temperature Annealing

Journal Article


Abstract


  • © 2018, The Minerals, Metals & Materials Society and ASM International. Ultrafine-grained copper sheets have potential micro-electro-mechanical applications. Copper sheets were fabricated using asymmetric rolling and asymmetric cryorolling, respectively, and they were annealed at 373 K for 1 hour. The asymmetric-cryorolled sheet has higher strength compared to the asymmetric-rolled sheet. Low-temperature annealing results in improved strength and ductility for the asymmetric-cryorolled sheet, while the strength was reduced for the asymmetric-rolled sheet. The asymmetric-cryorolled sheets have better thermal stability compared to asymmetric-rolled sheets due to their laminate structure.
