he Effect of Varying the Composition of Phosphorus on the Microstructure and Mechanical Properties of Tin-Bronze Alloys
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2013, Vol 3, Issue 3
Abstract
An investigation was carried out to assess the effect of phosphorus addition on copper- tin alloys. However, the effect of an increase in phosphorus above 0.25% has received little or no attention. Much effort has been expended only to study the effect of phosphorus as a deoxidizing agent on copper and its alloys. In this study, a new approach of casting phosphorus tin-bronze using an improvised vacuum crucible pots, made of clay mould was dopted. This method offers low cost and consumes less energy. The various microstructures that result from the slow cooling rate during the casting process enhance mechanical properties and were carefully examined. It was observed that the hardness and tensile strength increases as phosphorous content is increased from 0.1% to 1.0%. An optimum value of 0.9% phosphorus was obtained with corresponding hardness and tensile strength of 140HB and 912.26MPa respectively
