Influence of structural instability at the creep characteristics of constructing materials
The structural instability, which observed during the creep of constructing materials in different structural states, is the result from changes in the geometry of the applied stresses and strain rate and significantly influences on the creep characteristics. It is shown that the result of appearanc...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | The structural instability, which observed during the creep of constructing materials in different structural states, is the result from changes in the geometry of the applied stresses and strain rate and significantly influences on the creep characteristics. It is shown that the result of appearance of structural instability and the subsequent restructuring of Zr, ZrlNb, and Nb, subjected to severe plastic deformation, was the change in the law creep. Transformation of the structure of the steel 15Cr2NMFA during creep leads to changes in the character of plastic flow, the appearance of jumplike creep deformation especially at stresses close to the ultimate strength. |
