The effect of elevated temperatures on elastic and microplastic properties of ultrafine-grained titanium prepared by severe plastic deformation is discussed. Three sets of a-titanium VT1-0, Grade-4 and PT3-V which differ each other in polycrystal structure and impurity content were investigated. As experiments show, significant changes in grain sizes, elastic and microplastic properties were observed only for the purest titanium VT1-0. The thermal stability of other sets of titanium (Grade-4 and PT3-V) was found to be better; it is explained by higher impurity content in these materials.
