| Notes | silicon bronze;dieless drawing;microstructure and mechanical property QSi3-1 silicon bronze alloy wires were processed by dieless drawing with the feeding speed of 0.5mm· s^-1, the drawing speed of 0. 67-1. 00mm · s^-1 and the heating temperature of 600-800℃. Effects of drawing speed and heating temperature on microstructure and mechanical properties of the alloy were investigated. The results show that the average grain size of the alloy after dieless drawing is larger at a high heating temperature when the drawing speed and area reduction are given, while it is finer at a high drawing speed when the heating temperature is constant. The hardness and tensile strength of the alloy decrease rapidly at first and then slowly with the increase of heating temperature. Meanwhile, they increase slightly with increasing the drawing speed. The grains of the alloy undergo deformation refinement and subsequently swallowing up each other at a high temperature during dieless drawing process. 11-1800/TB WANG Zhen, LIU Xue-feng |
