چکیده مقاله
The effects of pass numbers on microstructure of Fe Al hybrid surface composites fabricated via plasma spraying and friction stir processing FSP were investigated Al Fe as sprayed surfaces were subjected to different one to four FSP passes Metallographic examinations and electron backscatter diffraction EBSD were used to analyze themicrostructure of different FSPed zones After applying the second FSP pass, Widm nstatten ferrite plates were formed from recrystallized austenite grains in stir zones SZs and heat affected zones HAZs By increasing the pass numbers, these grains were widened due to increasing the diffusivity of carbon and lengthened due to increasing heat inputs and increasing the microstructure anisotropy by producing more dislocations These grains were widened by increasing the pass numbers, due to increase the diffusivity of carbon and lengthened due to high heat inputs and microstructural anisotropy by producing more dislocations The microstructures of retreating side were also consisted of Widm nstatten ferrite EBSD analysis showed that no specific crystallographic texture was formed in the SZ as a result of FSP
