The Effects of Heat-treatment Process on Mechanical Properties and Microstructure for 1Cr17Ni2 Stainless Blade
The quenching temperature 1 060 ℃, 1 020 ℃ and 980 ℃, and the tempering temperature 640 ℃ and 540 ℃ were selected for the heat treatment process of 1Cr17Ni2 stainless steel, and the microstructure and mechanical properties of the sample were tested The results show that the free δ -Fe ferrite is formed after quenching at 1 060 ℃ and 1 020 ℃, the δ -Fe phase destroys the integrity of the martensite-strip cluster, resulting in the fracture of the impact sample, which shows the failure of tensile and impact performance . 980 ℃ quenching + 640 ℃ tempering can obtain fine sausteritic microsturcture with standard performance and both strength and toughness. The fracture of 540 ℃ tempering impact sample is quasi-cleavage fracture, which reflects the obvious embritleness of the second type of tempering, so the tempering between 480 ℃ and 540 ℃ should be avoided.
