AN UNBIASED VIEW OF OPTICAL GRADE POLYCRYSTALLINE DIAMOND CRYSTAL

An additional drawback is the fact specimen edges are stressed and, Unless of course the specimen sides are polished, and also its faces, misleading outcomes could possibly be obtained (Though this is not the case for chemically vapour-deposited diamond). A four-point bend test is often made use of because it stresses a bigger quantity of material

Photoelasticity is taken into account a practical measurement Software to the non-destructive and contactless dedication of mechanical stresses or strains within the manufacture of silicon wafers. It describes a alter during the indices of refraction of a cloth when the material is mechanically loaded. As silicon incorporates a diamond lattice fram
