Microstructure of a two-phase titanium alloy by rapid solidification technique

【摘要】 Ribbons of the two-phase titanium alloy were fabricated by single-roller rapid solidification technique,and aged at high temperature. The microstructure of ribbon samples were characterized with X-ray diffractometer(XRD) and environmental scanning electron microscope(ESEM). The microstructures of the alloy are composed of α phase and supersaturated β phase,and X-ray diffraction results show that all peaks of the α and β phases shift slightly to smaller angles,which can be explained by the disordering growth pattern caused by the rapid solidification process. After aging at 960 ℃ in vacuum,the ribbon is composed of homogeneous α phase and β phase.更多还原
