Study and Characterization of TiC/Fe Alloys by Gel-Casting

Article Preview

Abstract:

The TiC/Fe steel matrix composites were prepared by gelcasting technology of selecting the appropriate gel system and additives, the reasonable technological parameters. The toluene and 2-hydroxyethyl methacrylate (HEMA) were as gel system, oleic acid as dispersant. The rheological property, curing process and performance of the body were analyzed. The results show that the monomer (HEMA) content of 4.6wt% and oleic acid to 2wt% which increased the solid content from 50 to 54vol.%. The relative density of green body is 59.6%, the intensity is 28MPa. After sintering, the complicated shape was prepared.
