چکیده مقاله
The UNS32750 stainless steel and Titanium alloys are being extensively used in different industries such as aerospace, medical, and pipelines due to their great features of high temperature corrosion resistance, weldability, and high strength to weight ratio Therefore, the joining of these alloys is considered to be industrially effective and reduce costs The current study researches the dissimilar bonding and properties evaluation of Ti 6Al 4V to UNS32750 stainless steel joint using Transient Liquid Phase bonding The process was conducted at a constant time of 60 min and various temperatures of 900,950, and 1000oC with a Cu foil as an interlayer The microstructure evaluation and phase recognition were done using a Scanning Electron Microscope SEM with an equippedEnergy Dispersive Spectroscopy EDS feature Also, the X ray Diffraction analysis confirmed the formed phases which were predicted by the EDS analysis Increasing the temperature up to 950oC improved the strength value from 256 to 266 MPa While by reaching the highest temperature of 1000oC the strength value even dropped lower than that 900oC value to 240 MPa The strength increase is addressed by Isothermal Solidification Zone ISZ formation Although the joint of 1000oC showed a wider ISZ, the brittle Intermetallic Compounds IMCs existence such as FeTi, Fe2Ti, and Cr2Ti, especially at UNS32750/interlayer interface caused the joint to fail at lower applied stress
