Abstract
When Ti is cooled rapidly from the ? region, the ? ? ? martensitic transformation occurs. The transformed microstructure will be made up ? phase grains, and the original structure of prior ? grains is no longer evident from optical microscopy or electron microscopy. This paper demonstrates a simple way to well identify the transformation grain boundaries and accordingly reconstruct the prior grain structure through the use of electron backscattering diffraction on a scanning electron microscope. The approach is demonstrated for Ti and ?-Ti alloy, and it is thought to be applicable to other alloys such as in iron, zirconium which have an orientation relationship between prior and formed grains
