摘要：The mechanical properties of [Formula presented] alloy after flame rectification at 300 °C and 350 °C for different numbers of times were investigated, and the mechanism of precipitation transformation in [Formula presented] alloy was interpreted. The results show that the matrix precipitates (MPs) coarsened or diminished with increasing the number of times in flame rectification at 300 °C, and meanwhile the grain boundary precipitates (GBPs) dissolved. However, the matrix precipitates largely dissolved into the matrix and the grain boundary precipitates changed complicatedly with increasing the number of times in flame rectification at 350 °C. The difference of microstructure evolution after flame rectification at two temperatures led to significant differences in mechanical properties of [Formula presented] alloy. To conclude, the mechanical properties of [Formula presented] alloy achieved optimal after flame rectification at 350 °C for two times. © 2016 Elsevier B.V.
