Grinding burn - Preventing and Monitoring! – grindaix …
Grinding burn is caused by excessive heat dissipation into the part material. As materials cool as rapidly as they heat, the material undergoes a treatment similar to a tempering process. At high enough tensile stresses, caused by the grinding burn at the outer edges of the material rim zone, the material could undergo micro cracking.
Silicon Lattice - TU Wien
The crystal structure of silicon is classified under the diamond structure , and thus has two atoms in a primitive cell. Germanium, and carbon are further examples of a diamond structure lattice. On the contrary, the III-V semiconductors (GaAs, AlAs, InAs, InP etc.) are of zinc blende type.
