3D Additive Manufacturing: Microstructural Evolution of HSLA Steel in WAAM process

This research mainly investigates the relationship between the process condition, the microstructural evolution and the mechanical properties of the low carbon S690 steel in complex WAAM deposited structures. Besides, the optimum process parameters for improving the quality of the multi-pass multi-layer structure are also the research topic in...

Improvement of the Oxidation Resistance of the Single-Crystal Ni-Based TMS-82+ Superalloy by Ni–Al Coatings with/without the Diffusion Barrier

Oxidation behavior of the uncoated base, Ni–Al coated and Re–Cr-Ni plus Ni–Al coated single-crystal (SC) Ni-based TMS-82+ superalloy is studied under cyclic air at 900ºC for 200 h to assess the oxidation resistance. Regardless of the coating processing, Ni–Al coating is effective in improving the oxidation resistance due to the formation of a...
