Wear is a damage to solid surface that generally involves progressive loss of material and is due to relative motion between that surfaces. The present work aims to study the effects of Titanium (Ti) addition on wear behaviour of Powder Metallurgy (P/M) plain carbon steel. Elemental powders of atomized iron (Fe), graphite (C), and titanium were weighed accurately and homogeneously mixed to compose an alloy powders of Fe-1%C, Fe-1%C-1%Ti, then compacted into cylindrical billets of size (Ø25X33mm) using suitable circular die-punch set in a 100T capacity hydraulic press. The compacted specimens were subjected to sintering and subsequently sintered specimens were once again heated to a temperature 1000°C and hot upsetting was carried out on the heated specimens. Then the machining was performed on hot upset specimens to get wear test specimens of sizeϕ6X50mm. Using design of expert (DOE) software, the sliding wear experiments were planned on pin-on-disc Tribometer. The images of maximum worn out surfaces and microstructures of the alloy steels were captured and compared with wear behaviour of the alloy steels. The results are represented on 3D &2D Surface plot for comparing the response factors of both the alloy steels. It is found that the delamination wear is predominant at higher loads on both the alloy steels. The empirical equations for mass loss and coefficient of friction with respect to load and speed are developed for both the alloy steels.

Powder metallurgy is the science of procuring powder, consolidation into required shape and sintering it to obtain final product. The final density of the product depends upon the compaction pressure and sintering temperature. Thermal conductivity is a property to measure the heat conducting ability of the material. It depends upon the composition and porosity of the material. In this study, the thermal conductivity of Fe-Cu powder is studied and compared with plain iron powder prepared at the same density. Finely powdered metal powders are compacted in a die using an UTM machine. The disc obtained is sintered in a furnace to improve its strength. The thermal conductivity of Fe-Cu Powder alloy is found to be greater than that of plain iron powder because of the addition of copper, which has higher thermal conductivity. The Rockwell hardness value is also studied for the influence of hardness on thermal conductivity. The material developed can be used in various thermal applications like cooking ovens, clutch plates, and other industrial applications.
