Beschreibungen/Notizen

• The relative contributions of diffusion and sliding to the total strain of DC (diffusional creep) vary with the total strain ( epsilon exp T ), the ratio of thickness of layer being removed by diffusion to the grain dimension (X/a sub 0 ) and the degree of grain shape anisotropy (i.e. the b sub 0 /a sub 0 ratio). In view of these observations, it is not possible to uniquely separate the strain of diffusional creep into distinct contributions of diffusion and sliding. Consequently, the separation of total strain into diffusion and sliding contributions is of little significance. Magnesium- and zirconium-base alloys are discussed.
