High Strength, Utilizable Ductility and Electrical Conductivity in Cold Rolled Sheets of Cu-Cr-Zr-Ti Alloy
Source abstract
Abstract
The microstructure and properties of Cu-0.5Cr-0.03Zr-0.04Ti (wt.%) alloy subjected to cold rolling and aging were investigated using hardness and electrical conductivity measurement, tensile testing, and transmission electron microscopy. Plates subjected to 85% reduction in thickness showed significant improvement in the strength compared to solution treated and aged condition. By proper selection of aging temperature, ductility could be significantly improved without reduction in the strength. Aging of the cold rolled sheet at 420 °C for 1 h yielded an ultimate tensile strength and yield strength of 540 and 460 MPa, respectively. On the other hand, total and uniform elongation was 16 and 12%, respectively, with an electrical conductivity of 65 %IACS. The combination of properties achieved after cold rolling and aging is attributed to the higher dislocation density, ultrafine grains and nano-sized chromium precipitates.
