摘要
Inconel718是一种高强度耐热镍基合金,具有优良的高温强度、高温硬度和耐蚀性,在高温条件下能长期工作,已被广泛地应用于宇航工业、航空工业的涡轮发动机和相关零件的制造。分析Inconel718的机械性能、微观组织结构及其对切削加工性能的影响并进行了相关的试验验证,在试验数据的基础上,研究Inconel718中含碳量对切削过程中刀具磨损的影响。试验结果表明,Inconel718中含碳量在刀具后刀面磨损中起着非常重要的作用,Inconel718合金中含碳量越高,合金中所含的细微硬质夹杂物也越多,在切削过程中使刀具产生严重的后刀面磨粒磨损,从而降低材料的切削加工性。
The mechanical properties and microstructure of the superalloy Inconel 718 were analyzed. The machinability and behavior during machining the Incone1718 were also presented. The related industrial experiments were conducted to investigate the relationship between the carbon content and the corresponding tool wear of this workpiece material during metal cutting. The results showed that the carbon content of Ineonel 718 plays a key role in tool flank wear during machining. More serious wear was observed with the increase of carbon content.
