To understand the anisotropy dependence of the damage evolution and material removal
during the machining process of MgF 2 single crystals, nanoscratch tests of MgF 2 single …

S100/calgranulin polypeptides are present at sites of inflammation, likely released by
inflammatory cells targeted to such loci by a range of environmental cues. We report here …

Ductile-regime machining has been used to generate damage-free surface of hard and
brittle materials by setting the cutting depth to be smaller than the ductile-brittle transition …

High-strength ceramic materials are known for their exceptional mechanical properties;
however, they are often plagued by brittleness, limiting their applications. Because of the …

Scratching experiments were conducted on C-plane of sapphire along the [01 1 ̅ 0]
direction to investigate the evolution of material removal modes under varied scratching …

We report the mechanical behavior and deformation mechanisms in sapphire (Al 2 O 3)
studied using~ 1 µm diameter micro-pillar compression experiments performed in situ in a …

The cross scratching experiments were carried out on C-and M-planes of sapphire to
investigate the crystal-orientation dependence of crack initiation and damage mechanism …

Static and dynamic indentation experiments are conducted on sapphire along the c [0 0 0 1]
and a [1 1 2¯ 0] crystallographic axes to determine the loading rate dependence on its …

Surface-layer defects of M-plane sapphire caused by ultrasonic vibration-assisted cutting
were investigated in this paper through comparison cutting experiments. Topography …

Sapphire exhibits typical anisotropy due to its unique crystal structure, and there are
significant property differences in different processing areas during the machining of curved …
