Why elongation values decrease in metal matrix composites?
5 answers
The decrease in elongation values in metal matrix composites can be attributed to various factors outlined in the provided research contexts. When non-creeping reinforcing particles are added to metals, the creep rate of the composite significantly decreases, leading to reduced elongation. Additionally, the intentional introduction of porosity into the matrix reduces the elastic modulus of the matrix, shifting the composite's coefficient of thermal expansion (CTE) towards that of the reinforcing fibers, resulting in a decrease in CTE. Moreover, the addition of ceramic reinforcements to silver matrix composites effectively lowers the coefficients of thermal expansion, with the CTE decreasing as the reinforcement content increases due to the constraint effect provided by the reinforcements. These factors collectively contribute to the reduction in elongation values observed in metal matrix composites.
