The Model of Ultrasonic Superficial Plastic Deformation
Scientific substantiation and practical confirmation of possibility, expediency and efficiency of application of the ultrasonic superficial plastic deformation in zones of welded connections after performance of welding works is given. For this purpose a mathematical model of process of superficial plastic deformation is represent, as the hypercycle of loading consisting of elementary cycles – ...
متن کاملExperimental Effects Investigation of Ultrasonic Spot Welding on Dissimilar Al3105 and Al1050 Alloys Joining
The aluminum alloys of Al1050 with thickness of one millimeter and Al3105 with thickness of half millimeter were joined via ultrasonic spot welding (USW). To create a suitable welding, a vibrating horn (welding tool) fit to transducer and ultrasonic generator was designed using ANSYS software. Due to mechanical and thermal cycles during USW, both diffusion and mechanical mixing facilitated the...

متن کاملTransient Temperature and Heat Flux Measurement in Ultrasonic Joining of Battery Tabs Using Thin-Film Microsensors
Process physics understanding, real time monitoring, and control of various manufacturing processes, such as battery manufacturing, are crucial for product quality assurance. While ultrasonic welding has been used for joining batteries in electric vehicles (EVs), the welding physics, and process attributes, such as the heat generation and heat flow during the joining process, is still not well ...
متن کاملInfluence of Plastic Deformation on the Temperature Dependence of Ultrasonic Attenuation in Copper Single Crystals
The influence of plastic deformation (O<&<10%) on the MHz-ultrasonic attenuation a in single crystals of pure Cu, Cu50ppmAu and Cul30ppmAu has been measured over the temperature range 4<T<300K. The major contributions to the total attenuation originate from dislocation resonance, double-kink relaxation, phonon-electron interaction (at T<50K) and non-dislocation effects which are discussed espec...
