“…These kinds of alloys are widely used in bearing, gear, sleeve and structural parts due to their relative high mechanical properties, excellent heat treating properties and low cost, etc. (Maleque et al, 2013;Sharma et al, 2011;Youngblood et al, 1977;Shibata et al, 2006). In food and mining industries, the lubricating oil does not provide lubrication for mechanical parts due to pollution of oil or rigorous working conditions.…”

AbstractPurpose -The purpose of this study is to prepare new Fe-Cr-B alloys which have better wear resistance and investigate the wear mechanisms of these alloys tribotesting against SiC ceramic balls under dry sliding process. Design/methodology/approach -Fe-Cr matrix alloys were fabricated using powder metallurgy route. The tribological behaviors of Fe-Cr alloys tribotesting against SiC ceramic balls using a ball-on-disc tribotester were studied at different testing conditions. Meanwhile, microstructure, phases and morphology of worn surfaces were investigated. Findings -The element boron improved mechanical properties and tribological behavior of alloys. The friction coefficients of Fe-Cr matrix alloys did not show obvious difference. The specific wear rates of alloys decreased and then increased because of the brittleness of alloys with the increase of boron content. Fe-21 weight per cent Cr-7 weight per cent B alloy showed the best tribological properties in dry sliding. The wear mechanism of Fe-Cr alloy was plastic deformation and abrasive wear. However, the Fe-Cr-B alloys showed fatigue spalling characteristics. Originality/value -This paper reported a new, cheap and wear-resistant Fe matrix material to prepare mechanical parts in food and mining industrial fields.

Cracks due to segregation of Fe 3 P along the grain boundaries is a major problem in working of Fe-P alloys, processed in conventional wrought route. The present work deals with development of binary Fe-P alloys with varying content of phosphorus (in the range 0.1-0.35%) through powder metallurgical technique to obtain better mechanical properties without the problem of segregation. These alloys were processed into thin sheets by hot forging and rolling. The developed Fe-P alloy sheets were characterized in terms of microstructure, porosity and mechanical properties. Strength and hardness of Fe-P alloys increased with increase in phosphorus content and ductility slightly decreased. It has been observed that thin sheets of Fe-P alloys (with phosphorus as high as 0.25wt %) with high strength and moderate ductility can be obtained through powder metallurgy route and these alloys are free from embrittlement during working due to elimination of segregation problem.

This paper presents the sintering characteristics of Fe-based powder compacts formed through the warm compaction method. Iron powder ASC100.29 (73 wt%), chromium powder (22 wt%), and aluminium powder (5 wt%) were mixed mechanically for 60 mins in preparing the feedstock. The powder mixture was subsequently compacted at 200ºC through simultaneous loading of 325 MPa from upper and lower punches. The defectfree green compacts were then sintered in an argon gas fired furnace at a rate of 10ºC/min by varying the sintering time (30, 60, and 90 mins) and temperature (600, 750, and 900ºC), respectively. The sintered samples were characterized through physical and mechanical properties and their microstructures were analysed through scanning electron microscopy. The results revealed that sintering at 900ºC for 90 mins contributed to the highest volumetric expansion and relative density change, which are not expected in the powder metallurgy industries. A moderate sintering temperature of 750ºC for a holding time of 60 mins was found to produce a sintered sample with higher bending strength. In these sintering conditions, better dispersion of the alloyed elements is also observed.
