Overview on micro- and nanomechanical testing: New insights in interface plasticity and fracture at small length scales
TL;DR: In this paper, the challenges of instrumented micro-and nanomechanical testing at elevated temperature are summarized and a special focus is laid on the pitfalls of micro-compression testing with its stringent boundary conditions often hampering reliable experiments.
Journal ArticleDOI
Can microscale fracture tests provide reliable fracture toughness values? A case study in silicon
TL;DR: In this paper, four different fracture toughness test geometries in practice, all of them micromachined in the focused ion beam (FIB), were investigated to investigate the fracture toughness of Si(100) at the micrometer scale.
Journal ArticleDOI
Differences in deformation behavior of bicrystalline Cu micropillars containing a twin boundary or a large-angle grain boundary
Peter Julian Imrich,Christoph Kirchlechner,Christoph Kirchlechner,Christian Motz,Christian Motz,Gerhard Dehm,Gerhard Dehm +6 more
TL;DR: In this article, the authors used focused ion beam fabricated micrometer-sized bicrystalline Cu pillars including either a large-angle grain boundary (LAGB) or a coherent twin boundary (CTB) parallel to the compression axis and additionally on single-crystalline reference samples.
Journal ArticleDOI
Superlattice effect for enhanced fracture toughness of hard coatings
Rainer Hahn,Matthias Bartosik,Rafael Soler,Christoph Kirchlechner,Christoph Kirchlechner,Gerhard Dehm,Paul H. Mayrhofer +6 more
TL;DR: In this article, the authors employed in-situ micromechanical cantilever bending tests on free-standing TiN/CrN superlattice films and found that fracture toughness increases with decreasing bilayer period (Λ), reaching a maximum at Λ ǫ 6 nm.
Journal ArticleDOI
Methodology for studying strain inhomogeneities in polycrystalline thin films during in situ thermal loading using coherent x-ray diffraction
Nicolas Vaxelaire,Nicolas Vaxelaire,Henry Proudhon,Stéphane Labat,Stéphane Labat,Christoph Kirchlechner,Jozef Keckes,Vincent Jacques,S. Ravy,Samuel Forest,Olivier P. Thomas,Olivier P. Thomas +11 more
TL;DR: In this paper, a single grain within a polycrystalline thin film in situ during a thermal cycle has been monitored in situ at different temperatures, and the experimental approach and finite element simulation are described.
