Abstract
βSiAlON–cubic boron nitride (cBN) composites were consolidated by spark plasma sintering, and the effects of holding time and heating rate on the phase transformation of cBN and Vickers hardness were investigated. The cBN phase transformed into hexagonal BN (hBN) and the hardness decreased with increasing holding time. The phase transformation from cBN to hBN was retarded by increasing the heating rate, resulting in increased hardness.
