摘要: Abstract The microstructural changes which occur during the oxidation of α-titanium have been studied in temperature range 450–850°C. A 1 MV electron microscope containing a gas reaction chamber was used for direct continuous observation reaction. titanium dioxide (rutile) grows as highly porous epitaxial film with orientation relationship . generates sufficiently large stresses across oxide-metal interface to cause extensive plastic deformation thin foils microscopy. Direct lattice resolution studies show that porosity oxide develops from preferential growth islands regularly faulted on an initially dislocated film. presence any cold work metal or contaminant films its surface results production polycrystalline and enhanced rate.
