Dissimilar components composed of CFRTP (Carbon Fiber Reinforced Thermoplastic Polymer) and TC4 titanium alloy are increasingly applied in the aerospace field. The scanning mode offers a significant influence on quality laser joining joint between alloy. Therefore, with surface microgrooves has been implemented under oscillating linear respectively present research. temperature distribution is ...

The nature of the chemical mixing and microstructure gradients that occur across interface transition, when manufacturing tailored components with two high-performance dissimilar titanium alloys (Ti-6Al-4V (Ti-64) Ti-5Al-5V-5Mo-3Cr (Ti-5553)) by wire-arc additive (WAAM) process, are reported. It has been shown a relatively long-range gradient occurs during transition between layers produced dif...

In ferrite/austenite dissimilar metal welds, carbon can diffuse from the ferritic low-alloy steel to austenitic weld during heat treatment and thermal aging due large chromium content differences between two alloys. This influx leads precipitation of carbides in high-alloy metal, near fusion boundary, which affect properties joint. was investigated using multiple characterization techniques: el...
