Effects of Al3Ti and (Al,Ni)3Ti Addition on the Sintering of TiB2
Keyword(s):
ABSTRACTTitanium diboride has been sintered using spark plasma sintering (SPS). With the addition of tetragonal Al3Ti or cubic (Al,Ni)3Ti, the Vickers hardness, Hv, of TiB2 increases up to as high as 2000 by the sintering at 1273K, while that of the sample sintered without additives is as low as 20. Such a remarkable improvement is caused by the improvement of direct link between TiB2 grains in addition to the effect that Al3Ti or (Al,Ni)3Ti fills in the space between TiB2 grains and act as a binder.
