OSTI ID:6620388
Fracture toughening of partially stabilized ZrO/sub 2/ has been thermodynamically related to the coefficient of thermal expansion and the enthalpy of the phase transformation. Negative coefficients of thermal expansion and an enthalpy of 1.5 J/g were measured in commercial PSZ. Indentation cracking in brittle solids has been experimentally investigated and analyzed as a nonlinear fracture mechanics problem.
