The fracture toughness ( K Ic ) of a 90/10 glass‐matrix/metal‐particulate composite was measured as a function of treatment temperature and hold time. The toughness was 20% higher at a heat‐treatment temperature 15°C below T g than at the other four treatment temperatures examined. K Ic also varied as a function of time at temperature. The volume fraction of exposed particulate phase on the fracture surface was proportional to the increase in the fracture toughness.
