Determining the Correlation Between Vicker's Microhardness and Young's Modulus of Coal

Proceedings of the 2021 Asia Pacific Unconventional Resources Technology Conference, 2021
Coal mechanical properties are very important in assessing coal seam gas (CSG) borehole stability and reservoir permeability response to depletion. Obtaining coal directional mechanical properties can be challenging due to the lack of access to cores and the technical hurdle in making standard coal samples from cleated coal.

Vickers microhardness of semiconductor CuInSe2

Materials Science and Engineering: B, 1994
Abstract Vickers microhardness measurements were taken on the (112) face of bulk CuInSe2 crystal grown using a direct fusion technique followed by slow directional solidification. The method of preparation took 6–7 d. The lattice constants of the chalcopyrite structure are a o = 0.5788 ± 0.0001 nm and c o = 1.1617 ± 0.0004 ...

Vickers microhardness related to mechanical properties of polypropylene

Journal of Materials Science Letters, 1989
Vickers micro-indentation of polymers is a method that yields information about their microstructure and some aspects of their mechanical behaviour. In the case of polyethylenes of different types, a monotonic increase of the microhardness with increasing degree of crystallinity has been observed and it has been proved that the microhardness is related

Protoplastic effect and vickers microhardness in ZnS sphalerite

Scripta Materialia, 1996
A remarkable feature of the plasticity of a number of semiconductors, both elemental and compound, is the photoplastic effect (PPE). The PPE is the phenomenon in which the flow stress in straining tests is affected by illumination by a light near the fundamental absorption edge of the material.
