Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | It is determined that the mechanical properties of gazars depend on the degree and method of their deformation, changes in the porous structure. It is established that during rolling, the change in the strength properties of gazars occurs more intensively than when drawing by 25-40%. It is shown that the surface porous layers of gazars are intensively deformed, become practically monolithic and receive a high level of hard work, which sharply increases their strength. It is proved that deformed but not annealed samples have a strength of 2 ... 3 above higher than monolithic samples of the same dimensions. After annealing, the strength of gazars is 1.5 ... 2 above higher. The process of changing the structure of gazars after annealing for removing internal stresses is considered. Possible mechanisms for changing the porous structure of gazars and increasing their strength are proposed. |
