Several observations are made in the differential thermal analysis (DTA) test of solid zirconium (Zr) specimens. It is found that an increasing heating rate generally increases the solid-phase transition temperature for both nondeformed and cold-worked specimens, but to a different extent. Upon cycling the specimen with a constant heating rate, the phase transition temperature decreases initially during the first few runs and then remains constant. Also, holding a specimen for some time just before the phase transition during heating increases the phase transition temperature. Specimen heating history and prior cold work are also found to influence the solid-phase transition temperature.
