Abstract

The residual porosity is an unavoidable phenomenon of the components produced by powder metallurgy process which in turn largely affects the strength property of the same. Now a day it is possible to control the porosity of powder metallurgy components and retain them to the desired amount when required. The porosity of a powder metallurgy component greatly depends on the sintering temperature. In this study, the porosity variation of a powder metallurgy component with respect to its sintering temperature will be explored where the fractional porosity of the powder metallurgy component will be derived from the sintered density and also will be observed the hardness variation of the same with respect to sintering temperature. An experimental approach will be made to study the porosity, hardness and density variation of a powder metallurgy component with respect to its sintering temperature where the fractional porosity, hardness and density of the component will be derived. We have mainly focused on the effects of sintering temperature on physical properties of powder metallurgical components. We have done the process like Ball Milling Mixing method, single acting cold compaction method and use of vacuum furnace of pre-sintering and sintering of the compacts. The measurements are done using the rock well hardness tests and also some usage of Universal Testing Machine is also done
