Nickel based super-alloys are widely employed in aircraft engines and gas turbines due to their high temperature strength, corrosion resistance and, excellent thermal fatigue properties. Conversely, these alloys are very difficult to machine and cause rapid wear of the cutting tool, frequent tool changes are thus required resulting in low economy of the machining process. This study provides a detailed review of the tool wear mechanism in the machining of nickel based super-alloys. Typical tool wear mechanisms found by different researchers are analyzed in order to find out the most prevalent wear mechanism affecting the tool life. The review of existing works has revealed interesting findings about the tool wear mechanisms in the machining of these alloys. Adhesion wear is found to be the main phenomenon leading to the cutting tool wear in this study.

Low cycle fatigue tests were conducted on the single crystal nickel-based superalloy, DD6, with different crystallographic orientations (i.e., [001], [011], and [111]) and strain dwell types (i.e., tensile, compressive, and balanced types) at a certain high temperature. Given the material anisotropy and mean stress, both orientation factor and stress range were introduced to the Smith, Watson, and Topper (SWT) stress model to predict the fatigue life. Experimental results indicated that the fatigue properties of DD6 depend on both crystallographic orientation and loading types. The fatigue life of the tensile, compressive, and balanced strain dwell tests are shorter than those of continuous cycling tests without strain dwell because of the important creep effect. The predicted results of the proposed modified SWT stress method agree well with the experimental data.

Friction stir welding (FSW) process has gained attention in recent years because of its advantages over the conventional fusion welding process. These advantages include the absence of heat formation in the affected zone and the absence of large distortion, porosity, oxidation, and cracking. Experimental investigations are necessary to understand the physical behavior that causes the high tensile strength of welded joints of different metals and alloys. Existing literature indicates that tensile properties exhibit strong dependence on the rotational speed, traverse speed, and axial force of the tool that was used. Therefore, this study introduces the experimental procedure for measuring tensile properties, namely, ultimate tensile strength (UTS) and tensile elongation of the welded AA 7020 Al alloy. Experimental findings suggest that a welded part with high UTS can be achieved at a lower heat input compared with the high heat input condition. A numerical approach based on genetic programming is employed to produce the functional relationships between tensile properties and the three inputs (rotational speed, traverse speed, and axial force) of the FSW process. The formulated models were validated based on the experimental data, using the statistical metrics. The effect of the three inputs on the tensile properties was investigated using 2D and 3D analyses. A high UTS was achieved, including a rotational speed of 1050 r/min and traverse speed of 95 mm/min. The results also indicate that 8 kN axial force should be set prior to the FSW process.

基于性能化防火设计方法, 分析火灾条件下长大公路隧道内人 员疏散行为的特点,给出隧道内人 员疏散的安全判据,并结合某隧道 的结构及车流特征对人员疏散过程 进行了数值模拟研究,分析隧道在 正常通车和局部行车堵塞时,不同 火源位置、横通道间距与横通道宽 度对人员疏散时间及安全状态的影 响。结果表明,与建筑内人员疏散不 同,长大公路隧道内火灾的可用安 全疏散时间(ASET)与需要的安全疏 散时间(RSET)均为沿隧道长度方向 位置的函数。隧道内人员安全疏散 的时间曲线在各横通道疏散口出现 峰值,这主要是受到横通道通行能 力的限制,各疏散口人员集聚等待 所致。当隧道发生局部堵塞时,横 通道口需要的安全疏散时间显著增 加,危险性也急剧增大。隧道内人 员疏散的性能化防火设计应综合考 虑火源位置对人员载荷及疏散口位 置可用安全疏散时间的影响。该研 究为公路隧道火灾安全疏散设施的 优化设计提供依据。
