The structure changes were studied microscopically Cu-3%Ti alloys, which were solution-treated and aged at temperatures from 550° to 700°. The results obtained were as follows: (1) The grain boundary reaction were observed on the specimens aged at the temperature between 550° and 600°. The precipitates started to grow at grain boundaries, and spread gradually into the matrix. These regions with precipitates have the lamellar pearlite type structure, and the distance between the layers was about 2 microns or more. (2) The rate of growth of the pearlitic regions increases with higher aging temperature, as shown in the isothermal transformation curves. (3) Together with the pearlite type structure, Widmanstätten type structure was observed for the specimens which were aged at the temperature between 620° and 680°. (4) When aged at 700°, only Widmanstätted type structure could be found without any traces of pearlitic region. The size of the individual precipitates which can be found within the Widmanstätten structure increases with longer aging time.The shape of these precipitates was of a striped plate, and the distance between them is about 3 micronns. (5) The activation energy of the grain boundary reaction calculated from the data is about 45,000 cal/mol.
