Year: 2019
Type: article
Abstract: Experiments were conducted on Ti-6Al-4V alloy using abrasive water jet machining (AWJM) by varying process parameters such as water jet pressure, stand-off distance and abrasive flow rate. Surface integrity characteristics like surface roughness, surface hardness and microstructural evolution were studied. Effect of machining parameters on the surface and sub-surface hardness was determined. The grain size distribution, phase fractions, grain boundary deformation and grain boundary misorientation angle of the machined titanium (Ti6Al4V) alloy were studied using electron backscattered diffraction (EBSD) images. XRD images of machined Ti-6Al-4V samples were utilized to assess the peak shift and formation of new phases such as oxides. Crystallite size, dislocation density and lattice strain of the machined samples were evaluated using XRD results. Average grain size, mis-orientation angle, α and β phase fraction were evaluated with respect to AWJM parameters.
