摘　　要：使用ETM105D电子拉伸试验机对退火后的Monel 400合金丝材进行拉伸试验,并通过Matlab-MTEX软件统计再结晶体积分数的方法,研究了冷拔态Monel 400合金丝材在不同退火处理后的组织演变、力学性能及二者的关系,构建了Monel 400合金的再结晶模型,并计算其再结晶激活能。结果表明,用Matlab-MTEX软件处理EBSD数据得到的图像可以直观地呈现试样在经历退火处理后组织中晶粒的演变,以及更准确地统计再结晶的体积分数;选择825℃×20 min退火,可以获得较好的塑性和足够的强度。Tensile test of annealed Monel 400 alloy wire was carried out by using ETM105 D electronic tensile testing machine, and the microstructure evolution, mechanical properties and their relationship of the cold drawn Monel 400 alloy wire after different annealing treatments were studied by using Matlab-MTEX software to calculate recrystallization volume fraction. The results show that the image obtained by processing EBSD data with Matlab-METX software can intuitively present the evolution of grain in the specimen after annealing treatment, and more accurate statistics of the volume fraction of recrystallization. Good plasticity and sufficient strength can be obtained by annealing at 825 ℃ for 20 min.
