High-Resolution Acoustic Emission Monitoring in Nanomechanics

摘要: In many cases, the load–depth–time record in a nanomechanical or nanotribological test does not provide sufficient information, and subsequent microscopic imaging directly information on dynamics of process being studied. Analysis acoustic waves generated during these tests can overcome this drawback offer non-destructive way for obtaining complementary information. Acoustic emitted mechanical at nano/micro scale are rich source about deformation behavior that otherwise be inaccessible by traditional methods. emissions (AE) better understanding more complex interpretation results even scale. study, strength an AE-based method is demonstrated various types materials, including hard SiC coatings, silicalite-1 zeolite microcrystals, Fe3Si bulk partially stabilized zirconia explored using nano-indentation, nano-scratch repetitive nano-impact tests.
