Effect of Laser Spot Welding Variables on Microstructure and Mechanical Properties of the Ti-6AL-4V to AISI304 Dissimilar Joint
In this project, joining Ti-6Al-4V and AISI 304 dissimilar plates by laser-spot-welding method has been studied. In this regard, Ti-6Al-4V and AISI 304 plates, with a thickness of 0.7 and 0.5 respectively, were lap-welded using an interlayer of 0.2 & 0.3 mm copper and silver (pure silver). The process was done by 400Watt pulsed laser (Nd:YAG) using oncentric spot welding with 4mm diameter circl...

متن کاملNumerical and Experimental Investigation of Microstructure Evolution and Mechanical Behavior of Steel in Laser Forming
In laser forming, phase transformation and grain structural evolution in the heat affected zone (HAZ) take place under steep cooling rates and temperature gradients, and have a significant effect on the laser forming process and final mechanical properties of products. In this work, microstructure evolution during laser forming of AISI 1010 steel is experimentally and numerically investigated a...
متن کاملMicrostructure and Mechanical Properties of Direct Metal Laser Sintered Ti- 6al-4v
Direct metal laser sintering (DMLS) is a selective laser melting (SLM) manufacturing process that can produce near net shape parts from metallic powders. A range of materials are suitable for SLM; they include various metals such as titanium, steel, aluminium, and cobalt-chrome alloys. This paper forms part of a research drive that aims to evaluate the material performance of the SLM-manufactur...
متن کاملMicrostructure Integrated Modeling of Multiscan Laser Forming
Laser forming of steel is a hot forming process with high heating and cooling rate, during which strain hardening, dynamic recrystallization, and phase transformation take place. Numerical models considering strain rate and temperature effects only usually give unsatisfactory results when applied to multiscan laser forming operations. This is mainly due to the inadequate constitutive models emp...
