A range of mechanical properties of a coating/substrate system may be obtained using
indentation tests, and with the emergence of continuously recording indentation testing with …

The nanoscale pop-in phenomena in polycrystalline α-Al 2 O 3 and single crystal α-Al 2 O 3
(0 0 0 1) were comparatively investigated by nanoindentation with Berkovich indenters. It …

An attempt is made to explain the anisotropy of indentation-induced deformation and
fracture of sapphire for different crystallographic planes indented by a variously oriented …

The pop‐in behavior and mechanical properties of sapphire crystal vertically indented to its
rhombohedral R (10 2) plane were investigated by nanoindentation using a Berkovich …

Mechanical properties of a defect-free bulk GaN single crystal has been studied by
nanoindentation in the C (0001) surface. Our experiments provide consistent evaluations of …

This work clarifies the origin of the characteristic discontinuities registered during the
deformation of the (101̄0) plane of sapphire, by means of depth sensing indentation …

The anisotropic surface deformation of sapphire has been studied by means of depth-
sensing indentation experiments with a small-radius spherical indenter loaded onto the …

This study evaluated a novel approach for acoustic emission (AE) monitoring of
nanoindentation. The technique utilizes a miniature AE sensor integrated into a calibrated …

Single-crystal sapphire is utilized as a high-performance engineering material, especially in
extreme and harsh environments. However, due to its extreme hardness and brittleness, the …
