Study on Microstructure of High Manganese Steel Bonded Titanium Carbide
The microstructure,elements distribution and fracture morphology of high Mn steel bonded titanium carbide produced by vacuum sintering was analyzed by OM,SEM,EPMA and other techniques.Experimental results show that TiC particles distribute evenly in the binder and no segregation of TiC particles are observed.Mo is distributed concentrically and surrounding the carbide layer in the process of liguid phase sintering,which results in the formation of cladding structure.The structure is likely to improve the wettability,so the binder and the carbide are better combined.The structure also has an effect on the refinement of carbide particle.
