Lire la suite >Aluminum-Carbon Nano Fibers (CNF) composites produce by stir casting process present a yield strengths (YS) and an ultimate tensile strength (UTS) improved up to 33%. The hardening of the Al-CNF composite was considered as the sum of elementary contributions of effects: natural hardness of pure Al; grain size; dislocation density; elements in solid solution; CNF. In order to quantify CNF effect, calculation was performed to quantify the contribution to yield strength of each other's mechanisms. This theoretical calculation was compared to experimental results and the real effect of CNF on yield strength increase was estimated between 10 and 16%. [GRAPHICS] .Lire moins >
