Effect of soldering techniques and gap distance on tensile strength of soldered Ni-Cr alloy joint
PURPOSE The present study was intended to evaluate the effect of soldering techniques with infrared ray and gas torch under different gap distances (0.3 mm and 0.5 mm) on the tensile strength and surface porosity formation in Ni-Cr base metal alloy. MATERIALS AND METHODS Thirty five dumbbell shaped Ni-Cr alloy specimens were prepared and assigned to 5 groups according to the soldering method ...
متن کاملCeramics Bonding Using Solder Glass Frit
Ceramics bonding is becoming an important technology and has found wide applications in different engineering and electronic industries. In this paper, furnace bonding of ceramics using solder glass frit was investigated with emphasis on the effects of surface treatment and bonding conditions on bonding strength. Alumina (Al2O3) sheet and SCHOTT solder glass G017-393 were used as the base and b...
متن کاملbuckling of viscoelastic composite plates using the finite strip method
در سال های اخیر، تقاضای استفاده از تئوری خطی ویسکوالاستیسیته بیشتر شده است. با افزایش استفاده از کامپوزیت های پیشرفته در صنایع هوایی و همچنین استفاده روزافزون از مواد پلیمری، اهمیت روش های دقیق طراحی و تحلیل چنین ساختارهایی بیشتر شده است. این مواد جدید از خودشان رفتارهای مکانیکی ارائه می دهند که با تئوری های الاستیسیته و ویسکوزیته، نمی توان آن ها را توصیف کرد. این مواد، خواص ویسکوالاستیک دارند....
CALCULATION OF THERMODYNAMIC PROPERTIES OF Al-Fe, Al-Ni AND Ni-Fe ALLOYS USING FACTSAGE
Thermodynamic predicting analysis of three binary systems Al-Fe, Al-Ni and Ni-Fe are shown in this paper. Thermodynamic analysis involved calculation of activities, coefficient of activities, partial and integral values for enthalpies and Gibbs energies of mixing and excess energies at three different temperatures: 1873K, 1900K and 1973K, as well as calculated phase diagrams, for the investigat...
متن کاملInterfacial Reaction and IMC Growth of an Ultrasonically Soldered Cu/SAC305/Cu Structure during Isothermal Aging
In order to accelerate the growth of interfacial intermetallic compound (IMC) layers in a soldering structure, Cu/SAC305/Cu was first ultrasonically spot soldered and then subjected to isothermal aging. Relatively short vibration times, i.e., 400 ms and 800 ms, were used for the ultrasonic soldering. The isothermal aging was conducted at 150 °C for 0, 120, 240, and 360 h. The evolution of micro...
