| 摘 要： | The microstructural evolution and creep behavior of the Ti-43.5Al–4Nb–1Mo-0.1B alloy have been investigated by scanning electron microscope(SEM) and transmission electron microscope(TEM). The excellent creep property was obtained with a fully lamellar(FL) microstructure containing the least grain boundary βo phase(GB-βo).TEM results revealed that after creep testing the α2→βophase transformation was observed in the FL microstructure. The formation βophase is asso...
