The relationships of the precipitated metastable and stable phases with respect to the bulk properties of Mg‐PSZ were analyzed versus time and temperature. An application of the temparature‐time‐transformation diagram method detailed in a previous study was used to analyze the data. A new methodology is presented to compare the complex property relationships between the bulk properties and precipitated phases. Fracture toughness ( K IC ), Vickers hardness, as well as area fractions of unreacted secondary precipitate zones and grain boundary phase, were measured and plotted. For example, a maximum in fracture toughness was found to correlate with the disappearance of the unreacted secondary precipitate zones.
