Mechanically stable monoclinic zirconia-nickel composite
A dense (>98% theoretical density), residual‐stress‐free m‐ZrO2/40 vol% nickel composite with K IC∼ 5.4 MPa·m1/2 and ςf∼ 225 MPa has been obtained using a simple wet processing route and subsequent sintering at 1430°C in a 90% argon/10% hydrogen atmosphere. The mechanism for release of internal stresses by the composite developed during the t → m transformation on cooling is explained in terms of plastic flow in the infinite nickel cluster formed at the percolation threshold.
