Abstract
In order to improve the mechanical properties of polycrystalline cubic
boron nitride (cBN) and titanium carbide (TiC) composites (cBN-TiC),
this study developed a two-step sintering process. The relationship
between microstructure (structure and chemical composition) and
mechanical properties for the cBN-TiC composites were investigated.
The results indicated that less byproducts were contained in the cBN-TiC
composites fabricated by the two-step sintering than those by a
conventional sintering. In addition, no byproducts or defects were
observed between cBN and TiC grains. The mechanical-test results
confirmed that the two-step sintering indeed promoted the hardness and
transverse rupture strength of the cBN-TiC composites.
