Alloys in the Ti-Cu system with compositions close to the eutectoid exhibit potential for structural applications because they present interesting mechanical properties, low density, and high corrosion resistance. The mechanical behavior of these alloys depends directly on the processing conditions and heat treatments applied. Under thermodynamic equilibrium conditions, the microstructure of these alloys is formed by the alpha-phase and the Ti2Cu intermetallic compound. Depending on the processing conditions imposed, metastable structures may be formed. This study aimed to evaluate the microstructure and mechanical properties of near-eutectoid Ti-Cu alloys after aging heat treatment. Initially, samples were solution heat-treated at 1000 degrees C and water quenched (similar to 150 degrees C/s). Some of the samples were aged at a non-isothermal condition with a heating rate of 10 degrees C/min up to 400 degrees C, 500 degrees C, and 600 degrees C, followed by WQ. The heat-treatment results suggest that the highest value of mechanical strength corresponds to the loss of coherence between the Ti2Cu intermetallic compound precipitates and the matrix. (AU) | |
