... approaches. The predictive model has three main modules: process modeling, microstructure modeling, and fatigue modeling. In this paper, a detailed description and theoretical basis of each module is provided. Experimental validations (microstructure, porosity, and fatigue) of the tool using multiple...

... of SiC p from 15 wt % to 25 wt % in binary composite, density (2.8–2.9 g/cc), apparent porosity ( 1.4 – 3.4 vol % ), and hardness (78–93 BHN) were increased. For hybrid composite, density (2.9–2.76 g/cc) and hardness (93–81 BHN) were decreased with the increase in apparent porosity ( 3.4 – 4.1 vol...

... Optical Profilometer. NiCrAlY coatings had slightly lower average porosity and lower microhardness as compared to Ni - 20 Cr coatings. The observed erosion rate of the NiCrAlY coatings, however was lower than that of the Ni - 20 Cr coatings at both 30 and 90 deg impingement angles. Ni - 20 Cr coating had...
