STUDY ON THERMAL STRESS RELAXATION IN MAGNESIUM (Mg) MATRIX COMPOSITES AT HIGH TEMPERATURE
ABSTRAKT
AZ91D Mg alloy reinforced with fly-ash cenospheres (FAC) composites was prepared by a stirring method. According to the damping capacity and dynamic Young's modulus of the composites at high temperature, a model of thermal stress relaxation was applied to interpret the damping capacity with increase of temperature. The transient damping depends on the values of T/ω. The influence parameters of transient damping are deeply studied.
