Effects of Al3Ti Addition on the Sintering of TiB2

  • Masashi Yoshida (a1)

Abstract

Titanium diboride (TiB2) has been sintered using spark plasma sintering (SPS). With the addition of Al3Ti, the Vickers hardness, Hv, of TiB2 increases up to as high as 2100 by the sintering at 1273K, while that of the sample sintered without Al3Ti is as low as 20. Such a remarkable improvement is caused by the formation of rigid direct contacts between TiB2 grains in addition to the effect that Al3Ti fills in the space between TiB2 grains and acts as a binder.
