Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | For rapid fatigue life assessment of TiAl alloys,
the new method was proposed based on qualitative
and quantitative analyses. The qualitative
analysis was employed to illustrate the microstructure
effect for TiAl alloys on their fatigue
life. The new formula is derived for estimation
of the interaction forces of dislocations, which
yields quite satisfactory results. The results of
qualitative and quantitative analyses were used
to predict the fatigue life improvement by the
addition of trace elements producing grain refinement. |
