Microstructures and mechanical properties of Al 2 O 3 /AZ91 surface nanocomposite layer produced by friction stir processing
In this paper, the effects of friction stir processing (FSP) parameters on the mechanical properties and microstructures of as-cast magnesium AZ91 alloy are investigated. Grain-growth and microhardness of friction-stir-processed specimens with and without nano-sized aluminium oxide (Al 2 O 3 ) parti...
