considered the results of varied parameters applied throughout LCF tests on alloy seventy one eight
and bestowed a mathematical law relating obligatory strain vary, temperature and fatigue life.
This model corresponded to a polynomial law with five parameters and not but twelve
constants however with no links to the physical phenomena.
Taking under consideration the experimental information out there for every applied condition ( temperature
and strain controlled loading), all the opposite parameters being unbroken mounted as represented on top of,
we can get a median curve relating microstructure to fatigue life As a
result. the fatigue behavior of alloy 718 may be represented by Associate in Nursing empirical equation over the
entire vary of obtainable information.
