Cyclic Strain Localization Assessment by Advanced Microscopies
Résumé
The paper reports our interesting results gained during these last years
about the role of microstructure on strain localization of three different types of
metallic alloys. The benefit of using advanced techniques (TEM, AFM,
SEM-ECCI) is pointed out. Strain gradient and strain localization at microscopic
scale and strain partition at mesoscopic scale are discussed and allow explanations
for crack initiation site, precipitate dissolution or cyclic accommodation.
