Numerical and Experimental Study of Porosity Evolution during Plasma Spray Deposition of W,ty of the sprayed material. In the present paper, numerical and experimental studies on porosity evolution in plasma spray deposition of W are undertaken to provide insight into the formation and evolution of porosity. In the numerical study, deformation, interaction and solidification of molten dro

Thixoforming of Spray Cast Materials,processing provides several advantages over conventional casting, forging, and P/M techniques, but has not been accepted widely. Problems related to the methods for producing non-dendritic thixoworkable microstructures, and to process design and control must be addressed. In order to evaluate and ch

The alloy exhibited a maximum strain rate sensitivity of 0.3 and 190. elongation despite its initial fine grain size of 2 .m. This relatively low ductility is attributed to partially recrystallized microstructure and preferential distribution of f

Microstructures, Tensile Properties and Fatigue Crack Growth Behavior of the Zirconium Modified 202 Three concentrations of zirconium (0.12, 0.28 and 0.53 wt%) were selected to examine the effect of zirconium on the microstructures, tensile properties and fatigue crack growth behavior of the modified 2024 alloys. The results show that all as-spray deposited materials have acceptable densities (91
