Creep results in deformation while fatigue leads to crack propagation. Both ultimately lead to the failure of the material, by compromising its structural integrity and resulting in an eventual split or rupture. How to test for metal creep or fatigue The very earliest stages of creep happen on a molecular level and aren’t visible to the naked eye.
