Microstructure - Wikipedia

Microstructure is the very small scale structure of a material, defined as the structure of a prepared surface of material as revealed by an optical microscope above 25× magnification. The microstructure of a material (such as metals, polymers, ceramics or composites) can strongly influence physical properties such as strength, toughness, ductility, hardness, corrosion resistance, high/low ...

Investigation of the microstructure of platinum-modified ...

Abstract The high temperature performance of Pt-modified aluminide coatings is directly related to their composition and microstructure. In this work, several of the factors that control such features are investigated on a single crystal Ni base superalloy. It will be shown that the bi-phase PtAl 2 +(Ni,Pt)Al composition is more prone to occur at higher Pt surface concentrations, lower ...
