Production of N06625 alloy wire rod with large coil weight was realized by using the high-speed wire rolling mill,and the microstructure and properties after solution treatment at different temperatures(1000-1200 ℃)were studied.The results show that the grain size of the high speed rolled N06625 alloy wire rod is extremely small,and the reasonable solution treatment is at 1180-1200℃for 40 min.After solution treatment at 1200 ℃,the strength and hardness of the wire rod are low,and the elongation and reduction of area are excellent,which fully meet the subsequent drawing process.Besides,the microstructure of the wire rod is completely regulated,that is,static recrystallization is completed,where there are only a few small-sized Nb precipitates in the matrix,which will not affect the subsequent cold drawing deformation.
