Optical microscope, scanning electron microscope (SEM), and X-ray diffraction (XRD) examinations were performed to determine various characteristics, and additionally microhardness and conductivity measurements were conducted hereof. L18 Taguchi test design was conducted with three levels and six different parameters to determine the effect of such alterations on its machinability with WEDM, and post-processing kerf (cutting width) values were determined. Microchanges were ensured successfully by using applied heat treatments. Results obtained with the optimization technique of genetic algorithm gave minimum kerf. Values obtained by using response surface method along with this equation completely match with those achieved in the experiments. The best kerf value was obtained from sample E which was quenched from dual phase area. The microstructure of this sample was composed of primary alpha and alpha' phases.eninfo:eu-repo/semantics/closedAccessTi6Al4VHeat treatmentMicrostructureWEDMKerfGenetic algorithmArticle789-121573158310.1007/s00170-014-6702-x2-s2.0-84929340073Q1WOS:000354629200018Q2
