The precipitation kinetics of the quenched dilute Ti–1·6 at.-%N alloy has been followed by resistivity measurements at 77 K using the four probe method. Resistivity behaviour has been studied for various durations for the alloys aged in the temperature range 273–373 K. The resistivity behaviour has been explained on the basis of the growth and decay of interfacial strainfields associated with the precipitation process. In addition, the resistivity changes have been correlated with transmission electron microscopy observations.
