测定了承受弯曲应力的铍青铜(Q_(BC-1.75))片材在不同温度下的应力松驰曲线,拟合了松驰曲线方程,研究了温度、合金状态对松驰性能的影响.还对松驰过程做了定点金相观察和TEM组织分析.
The stress relaxation curves of beryllium bronze (Q_ (BC-1.75)) under bending stress were measured at different temperatures and the relaxation curve equation was fitted to study the effects of temperature and alloy state on relaxation properties. Fixed-point metallographic observation and TEM analysis of the relaxation process were performed.
