Abstract
The results of the investigation into the influence of thermomechanical treatment modes on the structure and anisotropy of mechanical properties of sheets made of the BrKh1Tsr chromium–zirconium bronze for the subsequent fabrication of current leads from them by bending. Thermomechanical treatment included quenching from 980 °C into water, cold rolling with various degrees of drafting (16 and 46 %), and age hardening at 475 °C for 3 h. Empirical dependences of ultimate strength and yield point as well as relative elongation of the sheets made of the BrKh1Tsr bronze on the degree of drafting during rolling are determined based on the results of tests for mechanical properties. It is established that the anisotropy of the rolled metal properties is insignificant and varies weakly at various treatment stages. The average grain size in the samples after various treatment varies insignificantly and constitutes 41,88–47,50 μm.
