Paper Abstract

Aluminium-silicon alloy or silurnin fabricated by powder metallurgy is a material widely used in aircraft and precision mechanics industries because of homogeneous composition and high mechanical properties. Residual stresses arising in this kind of composite material caused by the difference of thermal expansion coefficients of components have negative influence on the working of Al-Si parts and equipments. X-ray diffraction method of stress measurements is unique method allowing study the individual stresses acting in each component of composite material. In the present paper the stress distribution and mechanical behavior of aluminum matrix and silicon particles have been studied by X-ray diffraction method. Interpretation of experiment stress measurements was made on position of mechanics of composite materials.
