摘要：对几种铁、钛、镍基结构合金进行了表面完整性评价。研究的材料包括AISI 4340、4340改性、300级马氏体时效钢、Ti-6Al-6V-2Sn、Ti-6Al-2Sn-4Zr-2Mo、Inconel 718、AF95、Rene’80和AF2-1DA。在大多数情况下，这些合金经过淬火和回火或固溶处理和时效，以使它们达到高强度的结构状态。在以下金属去除条件下，上述合金的疲劳强度变化很大：表面磨削，手砂，端铣-周边切削，端铣-端切削，电火花加工和电解加工。为确保良好的表面完整性，已制定并在本报告中提出了航空航天硬件加工准则。刀具锐度的控制和加工参数的合理选择是首要要求。
Abstract : A surface integrity evaluation of several iron, titanium and nickel base structural alloys was completed. Materials investigated include AISI 4340, 4340 modified, Grade 300 Maraging Steel, Ti-6Al-6V-2Sn, Ti-6Al-2Sn-4Zr-2Mo, Inconel 718, AF95, Rene' 80 and AF2-1DA. For the most part, these alloys were quenched and tempered or solution treated and aged, as appropriate, to put them into a high strength structural condition. Wide variations in fatigue strength were documented for the above mentioned alloys under the following metal removal conditions: surface grinding, hand sanding, end milling-peripheral cutting, end milling-end cutting, EDM and ECM. Guidelines for processing of aerospace hardware in such a way as to assure good surface integrity have been developed and presented in this report. Control of cutting tool sharpness as well as proper selection of processing parameters are prime requirements.
