In the present scenario, Powder metallurgy (P/M) manufacturing process is one of the fastest growing fields which involves the processing of metal powders for the production of steels and has replaced all traditional methods of metal forming operations because of its low relative material wastage, low capital cost and maximum material utilization. Producing steels through the P/M route has immense potential for industrial applications in making components for machine parts, in the fields of automobiles such as fasteners, bearings, rollers, in manufacturing field such as tools, cutters, and also in the field of aerospace, defense etc. The microstructures and mechanical properties mainly depend on the final obtained density of sintered P/M alloy steels which will determine the component characteristics. The present study has been made to investigate the cutting tool wear behaviour of sintered/hot extruded P/M alloy steels with Fe-1% C as base material, W (Tungsten) and Ti (Titanium) as alloying elements. The cutting tool wear behavior was analyzed with the help of tool bits grounded from the head portion of extruded preforms with standard tool parameters for machining the non-ferrous materials by varying the cutting speed, whereas the feed and depth of cut was kept constant, and also the dry sliding wear behavior were studied on pin-on-disc (ASTM G99) arrangement. By using the optical microscopy (OM), the microstructure of extruded P/M alloy steels has been characterized to understand the structure-property relationships. The presence of WTi Carbide in both the extruded P/M alloy steels significantly enhances the tool wear resistance. Widmanstatten type ferrite-cementite matrix (alternate lamellas) microstructure is revealed on both the extruded P/M alloy steels. © 2015, Sphinx Knowledge House. All rights reserved.
