| 1 | Effect of Tool Shoulder and Pin Probe Profiles on Friction Stirred Aluminum Welds-a Comparative Study显示文摘在海洋的申请,海洋的等级钢通常被使用为拖并且上层建筑。然而,铝也由于它的小质量成为了一种好选择,当铝生锈与钢相比是最小的时。在磨擦上在这糊研究促使铝合金焊接被介绍。现在的调查处理不同磨擦的效果促使在机械强度和铝合金焊接的微观结构性质上焊接工具几何学。有肩膀和工具探查侧面的不同类型的三不同工具几何学根据设计矩阵在调查被使用。焊接上的每个工具肩膀和探查几何学的效果被评估。磨擦搅动焊接工具几何学,这也被观察在焊接加强, microhardness,和焊接强度上有重要效果。 | H.K.Mohanty M.M.Mahapatra P.Kumar P.Biswas N.R.Mandal | 2012 | Journal of Marine Science and Application2012，11，2： | 5 |
| 2 | Processing of RZ5-10wt%TiC in-situ magnesium matrix composite显示文摘This paper discusses processing in-situ RZ5-10wt%TiC composite fabricated by self-propagating high temperature(S.H.S)method where RZ5 Mg alloy was the matrix and TiC as reinforcement.The purpose of this study is to improve the mechanical properties and wear resistance of the RZ5 alloy used in aerospace application by adding TiC particles.The wear test was performed using pin-on-disc apparatus against 600 grit abrasive paper by varying the sliding distance and applied load.The composite was microstructurally characterized by X-ray diffraction(XRD),scanning electron microscopy(SEM)and energy dispersive X-ray spectroscopy(EDS).The results exhibited that the tensile strength and hardness of the RZ5-10wt%TiC composite increased considerably while grain size decreased compare to the unreinforced RZ5 alloy.The SEM based fractography indicated mixed mode(quasi-cleavage and ductile feature)failure of the composite. | Deepak Mehra M.M.Mahapatra S.P.Harsha | 2018 | Journal of Magnesium and Alloys2018，6，1： | 2 |
| 3 | 大型加强板结构焊接顺序的效果研究(英文)显示文摘Welding sequence has a significant effect on distortion pattern of large orthogonally stiffened panels normally used in ships and offshore structures. These deformations adversely affect the subsequent fitup and alignment of the adjacent panels. It may also result in loss of structural integrity. These panels primarily suffer from angular and buckling distortions. The extent of distortion depends on several parameters such as welding speed, plate thickness, welding current, voltage, restraints applied to the job while welding, thermal history as well as sequence of welding. Numerical modeling of welding and experimental validation of the FE model has been carried out for estimation of thermal history and resulting distortions. In the present work an FE model has been developed for studying the effect of welding sequence on the distortion pattern and its magnitude in fabrication of orthogonally stiffened plate panels. | Pankaj Biswas D.
