THE EFFECT OF HEAT TREATMENT ON ABRASIVE WEAR RESISTANCE OF Fe-34Cr-4.5C%WT HARDFACING ALLOY
Abstract: Hardfacing is one of the most useful and economical ways to increase the service life of components subjected to abrasive wear. Iron based hardfacing alloys have long been considered as candidate coatings for wear-resistant applications in industry. In the present work two layer of Fe-34Cr-4.5C%wt hardfacing alloy was deposited on ASTM A36 carbon steel plates by SMAW method. The m...
متن کاملEffect of Chromium Content on Microstructure and Wear Resistance of Fe-Cr-C Hard facing Layers
Layers of Fe-Cr-C Hard facing material containing various amounts of chromium were deposited on mild steel base metal. Optical Microscope (OM), Scanning Electron Microscope (SCM) and X-ray diffraction (XRD) were used to investigate the effect of chromium content of micro structural characteristics of Fe-Cr-C hard facing layers. The M7C3 carbide refinement mechanism exists on base metal. The exp...

15 صفحه اولWelding of titanium base alloys by tungsten-gas pulse arc process (PCGTAW) and investigation of frequency effect on microstructure and mechanical properties
In this research, Ti-6Al-4V alloy sheet with a thickness of one millimeter with butt joint design was welded by tungsten-gas arc welding process using pulse current (PCGTAW) and using AMS 4954G filler metal. In this study, the effect of pulse system frequency on microstructure and mechanical properties was investigated by optical microscopy, Vickers hardness and tensile strength tests. In the n...
