This paper aims to improve the oxidation resistance of MoNbTaVW (at%) refractory high-entropy alloys after flame tests at 1350 ℃ with Si/Al pack cementation coatings. After the Si/Al pack cementation coatings were applied, a coating layer of about
The microstructural and mechanical evaluation of 9% Ni steel with Flux-Cored Arc Welding was performed with two different Ni-based weld metals: Inconel 625 and Hastelloy 609. Weld metals showed the microstructural change depending on the temperature

Refractory metal alloys, such as Mo–Si–B systems, can extend high-temperature capability more than commercial Ni-based superalloys, but Mo–Si–B alloys require surface coatings to improve their poor oxidation resistance. In this study, alumini
