Grain Size Analysis with SEM

Grain size is an important feature that can determine strength, ductility, and toughness.  It is widely used to characterize geologic and metallic samples. Interestingly, the underlying mathematics enables snow science to use grain size to determine the bond strength of snow crystals and to predict the likelihood of avalanches....

Vickers Hardness testing

Hardness is defined as a material’s resistance to permanent deformation such as penetration or scratching. Static indentation tests are one way to determine hardness. For static indentation, a cone, pyramid, or ball is forced into the surface of the material. The relationship between the load applied for a given...
