Deformation in Nano Silicides
Strength properties are size dependent and increase with decreasing dimensions. The mechanical properties sharply deviate from those of macro-scale structures. It is expected to obtain improved strength properties in nano structures. Because the dislocation motion—if present at all—is restricted theoretical strength is anticipated. Contrary to macrostructures increase in strength is accompanied by increase in elongation. The theoretical tensile strength of MoSi2 and WSi2 were calculated and hardness measurements were measures. The hardness of β-FeSi2 which is a candidate to be applied as light emitting diode were measured by Berkovich indenter.
