摘要
采用不同的始锻温度、终锻温度和锻压速度对GH901高温合金涡轮轴毛坯进行了锻造,并分别进行了25℃室温和600℃高温环境下的耐磨损性能测试与分析。结果表明:在试验条件下,随始锻温度从1060℃升高至1140℃,终锻温度从860℃升高至940℃,或锻压速度从6 mm/s增加至12 mm/s,锻件的室温和高温磨损体积均先减小后增大,耐磨损性能先提高后下降。高温合金涡轮轴锻件始锻温度优选为1120℃,终锻温度优选为920℃,锻压速度为10 mm/s。
GH901 high temperature alloy turbine shaft blanks were forged at different initial forging temperatures, final forging temperatures and forging speeds. And the wear resistance of the forgings was tested and analysed at room temperature of 25℃ and high temperature of 600 ℃. The results show that under the condition of test, with initial forging temperature increasing from 1060℃ to 1140℃, final forging temperature increasing from 860℃ to 940 ℃, or forging speed increasing from 6 mm/s to 12 mm/s, the wear volumes of the forgings at room and high temperatures firstly decrease and then increase, the wear resistance firstly improves and then decreases. The optimized initial forging temperature, final forging temperature and forging speed are 1120, 920 ℃ and 10 ram/s, respectively.
