Damage evolution in dynamic deformation of silicon carbide

Impact damage on silicon carbide : first results

This paper deals with the damage of ceramic materials after impact. The main information on the phenomenology and the kinetic damage are often localized inside the Hertzian cone crack area [I]. With a ceramic tile target, it is not possible to obtain any information during the test. Therefore a new geometry of ceramic target, called "Match was developed in order to put crack gauge inside the He...

Sub-Surface Damage Removal in Fabrication & Polishing of Silicon Carbide

Silicon Carbide (SiC) is emerging as a promising substrate for systems which leverage the low lattice mismatch with Gallium Nitride (GaN), high power density, heat dissipation and radiation hardness properties unique to this semiconductor. Wafer fabrication and polishing of SiC substrates poses processing issues as a result of the material’s high Mohs hardness (~9.25), and chemical inertness. P...

Evolution of recorded microstructures in minerals during cooling of Zarrin intrusion, evidence for dynamic deformation

The Zarrin granitoids is located in the west of Yazd block, Central Iran. Zarrin granitoids exhibit mylonitic rocks ranging from protomylonitic to mylontic. In Zarrin granitoids examples of sub-magmatic, microstructures are represented by chessboard patterns in quartz and sub-magmatic fractures in plagioclase, indicating deformation at high-temperature conditions (T > 650º C) and the presence o...
