|
Mechanical rotor blades were forged under different die forging temperatures, and the thermal fatigue property and wear resistance were tested and analyzed. The results show that compared with the initial forging temperature of 910 ℃，the average depth and average width of main crack, and wear volume of the sample decrease by 35 %, 37 % and 40 % respectively at the initial forging temperature of 970 ℃. Compared with the final forging temperature of 780 ℃, the average depth and average width of main crack, and wear volume of the sample decrease by 38 %, 40 % and 43 % respectively at the final forging temperature of 820 ℃. With the initial forging temperature increasing from 910 ℃ to 1010 ℃, or the final forging temperature increasing from 780 ℃ to 860 ℃, the thermal fatigue property and wear resistance of mechanical rotor blade first increase and then decrease. The optimization parameters of die forging temperature for mechanical rotor blade are initial forging temperature of 970 ℃ and final forging temperature of 820 ℃.
