Abstract
Spray deposition and continuous extrusion (SD-CE) forming technique is a novel technology that combines spray forming and continuous extrusion. Al-20Si alloy rods with a diameter of 8 mm have been fabricated using SD-CE with different extrusion ratios. The microstructure and mechanical properties of these alloy rods were investigated. Al-20Si alloy can be refined effectively by SD-CE, resulting in a great improvement of mechanical properties. The strength and hardness of these alloys gradually increase with increasing the extrusion ratio. However, the elongation rapidly rises with the extrusion ratio, and then gradually drops as the extrusion ratio reach critical level.
