for desired criteria. Key words: laser transformation hardening; response surface methodology (RSM); unalloyed titanium; titanium; hardened-bead profile 1 Introduction Titanium and titanium alloys are excellent candidates for aerospace applications both in airframes and engine applications owing to their high strength to mass ratio and excellent corrosion resistance. Titanium alloys were......
existing bonding methods for titanium alloys, brazing and diffusion bonding are performed at a low temperature so that the grain growth can be restrained. However, the interfacial reactions between titanium alloys and brazing filler metals are hard to be controlled[8-9]. Compared with brazing, diffusion bonding is a recommended method for bonding of similar titanium alloys[10]. Furthermore......
Effect of combinative addition of mischmetal and titanium on the microstructure and mechanical properties of hypoeutectic Al-Si alloys used for brazing and/or welding consumables王博1,薛松柏1,王俭辛21... brazing and/or welding alloys were investigated by differential scanning calorimetry(DSC), optical microscopy(OM), scanning electron microscopy(SEM). The DSC results showed that an addition of RE......
