Abstract:

X-ray diffraction transmission electron microscopy, and measurements of microhardness and resistivity were used to study the formation of the orthorhombic O phase upon the alpha(2) -> O phase transformation. It has been found that the orthorhombic O phase is formed by the diffusion mechanism in the form of thin lamellar precipitates (domains). Upon subsequent growth, these domains form packets of twins with a twinning plane \{110\}. It is shown that the (130) twinning plane is not realized directly, but it appears as a result of joining of twin packets. No formation of an intermediate metastable phase was observed upon this transformation.
