| Abstract Scope |
Due to the combination of high strength and reasonable ductility, beta titanium alloys become a promising candidate for future application in biomedical implants as well as aerospace components. Understanding the microstructure evolution in beta titanium alloy is integral to manipulating its structural property relationships. The microstructure evolution in Ti-5Al-5Mo-5V-3Cr during the continuous heating at the rate of 5°C/min and 100°C/min were characterized using scanning electron microscopy and transmission electron microscopy. Fine scale alpha precipitates could be formed homogeneously within the beta phase matrix during the slow, continuous heating, while coarse, black-plate alpha was formed during fast continuous heating. The role metastable omega particles play during the following alpha precipitation has been identified. The structural, morphological and crystallography characteristics of the alpha lath during the initial stage of precipitation have been studied in details. |
