INVESTIGATION OF THE EFFECT OF CURRENT ON

The results of the investigation indicate the welding current to be the most significant parameter controlling the weld tensile strength as well as the nugget diameter. The contribution of welding current holding time and pressure to tensile strength are 61%, 29%, 4% respectively and the contribution of these parameters to nugget diameter are 81%, 17%, 1.7% respectively.

Investigation of the Intermetallic Formation on Wet Underwater Welding of AISI 4012 Steel The objectives of the study is to investigate the formation of intermetallic compound and the An Investigation of Copper Dissolution and the Formation Dec 17, 2008 · "An Investigation of Copper Dissolution and the Formation of Intermetallic Compounds in Molten Tin and Tin-Silver Solders." Proceedings of the ASME 2003 Heat Transfer Summer Conference. Heat Transfer:Volume 3. Las Vegas, Nevada, USA. July 2123, 2003. pp. 289-294. ASME. Corrosion Study and Intermetallics Formation in Gold The intermetallic growth mechanisms of Cu on Al pad metallization has been studied by a few researchers [2,3,6]. The activation energy reported varies from a wide range of 10.71 kJ/mol to 60.9 kJ/mol. The thin Al metallization could be an important factor in affecting the rate of formation of

intermetallic formed. The study will attempt to produce level 1, level 2, and level 3 corrosion as denoted by IPC-4552 rev A and tabulate wetting balance results and congruity of intermetallic formed. Key words:ENIG, corrosion, intermetallic formation, solder wetting balance . INTRODUCTION . ENIG was introduced to the industry in the mid-1990s Formation Investigation of Intermetallic Compounds of materials Article Formation Investigation of Intermetallic Compounds of Thick Plate Al/Mg Alloys Joint by Friction Stir Welding Yang Xu 1, Liming Ke 1,2,*, Yuqing Mao 2, Qiang Liu 2, Jilin Xie 2 and Haoran Zeng 2 1 State Key Laboratory of Solidication Processing, Northwestern Polytechnical University, Xian 710072, China 2 National Defence Key Discipline Laboratory of Light Alloy Formation Investigation of Intermetallic Compounds of materials Article Formation Investigation of Intermetallic Compounds of Thick Plate Al/Mg Alloys Joint by Friction Stir Welding Yang Xu 1, Liming Ke 1,2,*, Yuqing Mao 2, Qiang Liu 2, Jilin Xie 2 and Haoran Zeng 2 1 State Key Laboratory of Solidication Processing, Northwestern Polytechnical University, Xian 710072, China 2 National Defence Key Discipline Laboratory of Light Alloy

Impact of Intermetallic Growth on the Mechanical

The need to understand the intermetallic formation, structure, and its impact on the Further wet grinding on As a preliminary investigation of the mechanical strength of Pb-free interconnects, four-point bending tests were performed to simulate the shipping Influence of benzene on the Ni3Fe nanocrystalline Feb 15, 2011 · The X-ray diffraction patterns of the as-milled samples and of the milled and subsequently annealed samples show the progressive alloy formation.It was concluded that the Ni 3 Fe intermetallic compound is mainly formed after 2 h of wet milling and subsequent annealing. A complete analysis of the influence of the wet milling on the structural and magnetic properties of Ni 3 Fe nanocrystalline Investigation of growth behavior of AlCu intermetallic Formation energy of AlCu is compatible but slightly lower to that of Al 4 Cu 9, suggesting AlCu tends to be the most stable phase among all. The reason why the Al layer is completely consumed in one case and some Al layer remains in the other is due to the fact that the formation of AlCu requires more than twice the amount of Al than Al 4 Cu 9

Investigation of growth behavior of AlCu intermetallic

Jan 01, 2011 · Earlier studies on the AlCu diffusion couple have confirmed that the -Al 2 Cu is the first compound nucleating at the AlCu interface. However, contradictory findings in subsequent AlCu phase formation, either -Al 4 Cu 9 or -AlCu being the main phase, vary among researchers , .This issue remains open in the IMC formation in AlCu wire bonding. Investigation of the Role of Void Formation at the Cu-to The Sn finish provides an initial Cu-Sn intermetallic layer, while the Ag finish and OSP coating allows the formation of the initial Cu-Sn intermetallic during the reflow cycle. Drop test results for assemblies as-built and as a function of aging at 125 degC are correlated with cross-sectional analysis of Investigation of the wetting properties of Cu6Sn5 Sep 29, 2020 · The formation and growth of intermetallic compound (IMC) layer at the interface between Sn3.5Ag lead-free solder and the Cu substrate during soldering and aging were studied.
