便携氢分析仪

X射线衍射法是表面/次表面残余应力测定技术中为数不多的无损检测法之一，是根据材料或制品晶面间距的变化测定应力的，至今仍然是研究较为广泛、深入、成熟的残余应力分析和检测方法之一，被广泛的应用于科学研究和工业生产的各领域。2012年日本Pulstec公司开发出基于全二维探测器技术的新一代X射线残余应力分析仪——μ-X360n，将利用X射线研究残余应力的测量速度和精度推到了一个全新的高度，设备推出不久便得到业界的广泛好评。由于其技术先进、测试数据可重复性高、使用便携等优势，一经推出便备受业界青睐！圆形全二维面探测器一个突出的优势就是X射线单角度一次入射到样品即可得到一个完整的德拜环，一次性获得500个数据点进行高精度数据计算，因而不再需要测角仪，从而摆脱了测角仪对不规则形状样品测试局限，使斜面、弧面、球面等不规则形状样品的残余应力测量成为了可能。除常规样品外，基于全二维面探技术的便携式X射线残余应力分析仪可以测试圆棒、轴承、底盘、螺丝、滚珠丝杠/杆、消声器、连杆、排气管、吊挂构件、角焊区、齿轮齿牙、车轮、管道、油罐、各种压力容器、桥梁等各种工件和构件的残余应力，其中以焊接残余应力检测/焊缝残余应力检测、管道残余应力（尤其钢管残余应力）检测、切削残余应力检测、油罐残余应力检测和齿轮残余应力检测在工业和科研中应用为广泛。2018年，日本Pulstec公司成功克服技术难点，发布了新的产品型号：μ-X360s，将全二维面探测器技术的产品设计和功能完善再次升！目前，PULSTEC已经在全球17个安装了超过450台便携式X射线残余应力分析仪，被用于诸多大学和研究实验室中，包括日本、美国、英国、德国、中国和新加坡，以及许多工程制造企业，特别是诸如汽车、机械、航空航天领域等等各个行业，众多客户也进行了很多有意义的研究工作并发表了大量文章，近期我们对这些文章进行收集并按照应用及不同材料归类整理，希望可以帮助广大科研工作者更好了解PULSTEC μ-X360系列残余应力分析仪的强大能力及广泛应用。一、焊接●Increase of bending fatigue resistance for tungsten inert gas welded SS400 steel plates using friction stir processing, Materials and Design 61 (2014) 275-280●Practical examination of the welding residual stress in view of low-carbon steel welds, J MATER RES TECHNOL. 2020 9(3): 2717–2726●Investigation of the Residual Stress in a Multi-Pass T-Welded Joint Using Low Transformation Temperature Welding Wire, Materials 2021, 14, 325.●Measurement of Residual Stress in Arc Welded Lap Joints by cosα X-ray Diffraction Method, Journal of Materials Processing Technology, Volume 243, 2017, Pages 387-394●Prediction of residual stresses induced by low transformation temperature weld wires and its validation using the contour method, Marine Structures 44 (2015) 232-253●焊接工艺对SUS301L不锈钢残余应力的影响，Electric Welding Machine Vol. 48 No. 3●不锈钢冷金属过渡焊角接接头应力及变形规律研究，Electric Welding Machine Vol. 47 No. 12 二、铝及铝合金●Influences of residual stresses and initial distortion on spring backprediction of 7B04-T651 aluminium plates in creep-age forming, International Journal of Mechanical Sciences 103(2015) 115–126●The influence of alloy composition on residual stresses in heat treated aluminium alloys, Materials Characterization 105 (2015) 47–55●A parametric study of laser spot size and coverage on the laser shock peening induced residual stress in thin aluminium samples, The Journal of Engineering Volume 2015 Issue13●Effect of cutting parameters on the residual stress distribution generated by pocket milling of 2219 aluminum alloy, Advances in Mechanical Engineering 2018 Vol. 10(12) 1–15●Intermethod comparison and evaluation of near surface residual stress in aluminum parts subject to various milling parameters, 2019 Annual Conference on Experimental and Applied Mechanics Vol. 6●Depth Profile of Residual Stresses to Analyze Textures in Extruded A6XXX, 2021 IOP Conf.
