Effect of 1 080 ~ 1 200 ℃ solution temperature on structure and mechanical properties of hat rolled Inconel 601 alloy is studied by means of optical microscope
scanning electron microscopy
hardness tester and tensile tester. The results show that the structure of the hot rolled alloy matrix is elongated austenite grain structure with less dispersed nitride
but the massive carbide precipitated along austenite grain boundary. With the increasing solution temperature
the recrystallization grain size increases gradually
the carbide dissolves slowly
the strength and hardness decrease gradually. When the solution temperature is 1 160 ℃,the crystal grain size is uniform
the carbide dissolves completely
the HRB hardness value of alloy decreases from 84 to 71
and the elongation increases from 52% to 70%. The best mechanical properties of alloy can be obtained by solid solution treated process at 1 140 ~ 1 160 ℃ for 50 min.
