Laser fabrication of Ti6Al4V/TiC composites using simultaneous powder and wire feed
چکیده انگلیسی

Composites of Ti–6Al–4V containing different volume fractions of TiC were manufactured using direct laser fabrication. Ti–6Al–4V wire and TiC powder were fed into the laser with the rate of powder feed being changed so that samples containing different volume fractions of TiC could be manufactured. Optical microscopy, scanning electron and transmission electron microscopy were used to characterise the microstructure of these samples. The room temperature tensile properties were measured also on some selected compositions together with their Young's moduli. In addition the change in wear resistance was studied as a function of TiC volume fraction using a standard wear test. These observations are discussed in terms of the advantages and difficulties of using simultaneous wire and powder feed systems and in terms of the value of this approach in obtaining data over a wide range of compositions for such a composite.
