Abstract
A powder metallurgical aluminum alloy and forging technology have been developed to mass produce high-performance-engine pistons. An Al-Si based powder metallurgical alloy containing 2mass% SiC particles and 5mass% Fe has shown much higher fatigue strength as well as better wear resistance than a conventional cast piston alloy. In order to draw out the alloy's formability, the forging has been programmed using an integrated process that involves the precise control on the die temperatures and the spray conditions of the lubricant. With these procedures, near-net-shaped pistons are efficiently obtained. The newly developed pistons have improved engine performance and are being put into practical use in Yamaha's commercially available snowmobiles.
