Vacuum Brazing of Zirconium-Based Alloy and 321 Stainless Steel Using Titanium Based Filler Metal
Both Zirconium-based alloys and 321stainless steel are widely used as engineering alloys due to their good mechanical properties. Conventional fusion welding techniques for Zr alloys and stainless steel are not feasible due to the formation of brittle intermetallic compounds such as (Zr3Fe, ZrFe2 and Zr2Fe) and corrosion cracking. Brazing is one of the most wide...
متن کاملTransmission Electron Microscopy Sample Preparation of INCONEL 738 Nickel-Base Superalloy
Size, shape, volume fraction and distribution of embedded g/ phase in g phase has direct effect on strength of INCONEL alloy. Microstructure parameters of INCONEL phases are quantified from microstructure images using transmission electron microscopy (TEM). Different TEM sample preparation techniques were used to study INCONEL 738 alloy microstructure for transmission electron micros...
متن کاملOptimization of vacuum brazing process parameters in AA6061 using Taguchi method
Vacuum brazing products have excellent joining quality, less deformation and fewer residual stresses. The vacuum brazing technique has significant effect on the microstructure and property of the aluminum brazed joint, but there is little discussion about the optimization of the process. This study investigates how different process parameters affect the tensile properties of 6061-T6 aluminum v...
متن کاملMicrostructure and micro-texture evolution during large strain deformation of Inconel alloy IN718
Article history: Received 2 January 2015 Received in revised form 22 October 2015 Accepted 23 October 2015 Available online 27 October 2015 The hot deformation behaviour of Inconel alloy IN718 was studied in the temperature range of 950–1100 °C and at strain rates of 0.01 and 1 s with a view to understand the microstructural evolution as a function of strain rate and temperature. For this purpo...
متن کاملSuperplastic Forming of Inconel Alloy 718spf
Superplasticforming (SPF) has become an important manufacturing method for aerospace and fuselage components. The basic reasons for the popularity of this process are reviewed and the compatibilityoffine-grained INCONELB alloy71 8SPF@ to superplasticforming are presented in this paper. The temperature limitations of current aluminum and titanium alloys employed in SPF parts for gas turbine comp...
