AZ91 Magnezyum Alaşımının İşlenebilirliği (Machinability of AZ91 Magnesium Alloy,Machinability of Magnesium)

Abstract

The increase in environmental pollution and the decrease of energy resources attached importance to both ecological and environmentalist designs. Therefore, today meeting the requirements of less fuel consumption in the automotive industry has been an important factor. One of the important ways to meet those requirements is to reduce the weight of the vehicles. With such a feature Magnesium and magnesium alloys make it possible to reduce the weight of the vehicles- at a rate of %35 and since the density of magnesium is about 1.7 g/cm the magnesium has been a fundamental construction material. Magnesium alloys have % 33 less density when compared with aluminum and %77 when compared with steel. Therefore, Magnesium and magnesium alloys are used in a wide variety of structural applications including portable microelectronics and telecommunication, automotive, materials-handling and aerospace industries due to their low density. In this study, AZ-series magnesium alloys AZ9 l magnesium alloy is widely used, machining parameters, cutting forces and chip formation and surface roughness were investigated. Its the experimental study, AZ9 I chip cutting speed and cutting depth parameters with surface roughness values obtained from the types of chips were a close relationship.
