Elevated temperature mechanical properties of Al-8.5Fe-1.3V-1.7Si/SiCp composite prepared by multi-layer spray deposition

Al-8.5Fe-1.3V-1.7Si/SiCp composite prepared by multi-layer spray deposition in different states were investigated.Ultimate tensile strengths of the composite sheets as-rolled tested at 315 ℃ and 400 ℃ are up to 300MPa and 186MPa respectively.The fine dispersoids and fine grains,and homogeneous SiC particles contribute to the excellent mechanical properties of the composite at elevated temperature.Specially,partial dissolution of SiC particles contributes to the stability of Al12(Fe,V)3Si phase.
