【摘要】 研究两种不同热处理工艺对1Cr17Ni2钢材料性能的影响。通过相关的性能试验进行对比研究,试验包括抗拉试验、冲击韧度、应力腐蚀、常温拉伸疲劳、超声疲劳试验。研究结论为,对于1Cr17Ni2钢,使用相应于830 MPa名义强度的热处理工艺,材料的综合性能优于名义强度为1 080 MPa的热处理工艺,这对在航空紧固件结构中合理选用1Cr17Ni2钢有实际指导意义。更多还原

【Abstract】 Material properties are affected by heat-treatment greatly.It is studied what effect two different heat-treatments have on general properties of 1Cr17Ni2 fasteners by tests.These tests included tensile strength test,notch durability test,stress corrosion test and fatigue test.Through those tests,a conclusion is gained that high temperature backfire heat-treatment make general properties of 1Cr17Ni2 better.Nominal intensity of material using this heat-treatment is 830?MPa.It is useful for choosing 1Cr17Ni2 in reason in the structure during manufacturing aircrafts.更多还原
