|Title:||CHARACTERISTICS OF COLD WORKED AL-SI SPRAY FORMED PARTS|
METALLURGICAL AND MATERIALS ENGINEERING
|Abstract:||Al alloys has high strength, low density, good wear resistance, low coefficient of thermal expansion. Its low density, which can contribute significantly to the aspect of weight savings in the design and construction of automotive and aerospace components, materials handling equipment, portable tools and even sporting goods. These properties can be improved by the mechanical processing. By these processes mechanical properties such as ultimate strength, yield strength and percentage elongation and microstructure of the Al alloy may be improved.A rolling thickness reduction of 5% produces Al—Si strip having optimum properties. The mechanism of densification in the deposit layer during rolling has been discussed on the basis ofthe examination of the microstructure of the deposit at different stages of rolling. It is obserbd that the wear behaviour is affected by varios mechanical properties The wear behaviour is also dependent on the load and hardness.|
