摘要：
The precipitates present in a controlled rolled, low carbon, Ti-Nb microalloyed steel have been studied on reheating to 850-1400-degrees-C. Below 110-degrees-C (Nb(rich),Ti) spheres dissolve and coarsen, and spherical caps and nodules of (Nb(rich),Ti) appear on the faces and corners of (Ti(rich),Nb) cubes and laths . A1N coprecipitates with many of the caps and cubes. At higher temperatures than 1100-degrees-C, Nb(rich) spheres and caps dissolve completely, leaving only Ti(rich) cubes and laths , which are stable to 1400-degrees-C. Characteristically, these are compositionally cored and laths are richer than the cubes.
