Внутрішнє тертя волокнистого композиційного матеріалу алюміній-бор

Abstract

The method of mechanical spectroscopy is to diagnose the condition of the defected structure of fibrous composite materials of aluminum-boron based on aluminum alloys М-40, Aмg6. Analysis of the presence and degree of perfection of the existing substructure was carried out measuring the temperature and amplitude dependence of internal friction. The possibilities are revealed to ensure the high-strength state of composite materials based on aluminum and its alloys armoured with boron fibres by forming substructure in a matrix and its stabilizing with impurity atoms, Complexes of such atoms, and disperse phases.
