Özet

In this study, the optimized sintering parameters for a feedstock obtained by mixing the powder of Ti-6Al-7Nb and 31wt% binder system (comprised of high-density polyethylene, Polypropylene, PEG 20000, paraffin wax and stearic acid), were determined. In order to produce a component, Taguchi method was applied to obtain the optimum conditions. As a result of ANOVA, sintering temperature was proven to be the most effective one. It was also proven that for feedstock comprised of 69wt% Ti-6Al-7Nb powder, the suitable set of sintering parameters were as follows: sintering temperature of 1250 degrees C, dwell time of 60 min, heating rate of 1 degrees C/min, gas flow rate of 5 L/min.
