Abstract

This paper shows the effect of silicon on structural and phase transformations in aluminum-chromium powder compacts during heating in the ambient air at 500°C. Samples were obtained by pressing from a mixture of the powders. The studies were carried out by using X-ray diffraction and metallographic analysis, and measuring the weight gain of the samples. It was found that silicon additives (10-20 at %) block the reaction interaction of aluminum and chromium, that occurred in two-component mixtures (Al-Cr) at 500°C and prevent a significant volume growth of the compacts.
