Abstract

This article submits the synthesis of theoretical analysis and experimental investigation on the mechanical behavior of thermally sprayed continuous fiber-reinforced metal-matrix composites. Special attention is drawn to the relationships among processing parameters, fiber-matrix interface, and composite properties. The evaluation concerns austenitic steel fiber-reinforced NiCrAI alloys with up to 30% of filament volume content. For the selected model system, the tensile and flexural sample loading is performed. In situ scanning electron microscopy (SEM) bending tests were used to investigate crack propagation and failure modes in the composites. Theoretical predictions of composite mechanical properties are compared with experimental observations.
