SINTERING OF IRON POWDER MIXTURES AND DETERMINING THEIR MECHANICAL PROPERTIES

In this investigation, iron-based powder-metal compacts with two distinctive mesh sizes were sintered utilizing microwave heating framework. Iron-based powders of 100 mesh and 300 mesh were blended with mass portions w =2 % copper (Cu) and 2 % aluminium (Al) and also only with 2% aluminium (Al). PM samples are sintered at a frequency of 2.4GHz at 3kW and a temperature of 700 °C for 45 minutes in normal atmosphere. Mechanical properties, microstructure, and hardness were explored for this sintered component. The most elevated mechanical properties are obtained for 300 mesh, iron-based PM compacts with 2 % Cu and 2% aluminium. KEYWORDS: Mesh Sizes, Sintering, Microwave Sintering, Microstructure & Hardness
