Enhancement of Impact Abrasion Resistance Performances of White Cast Iron Utilizing Ti(3)AlC(2)
Al-Ti-C master alloy agent is currently the most promising grain refiner. This work investigates the influence of Ti(3)AlC(2) addition (1.0–3.0 wt.%) on the microstructure of a hypoeutectic cast iron (4.7 wt.% Cr, 2.3 wt.% C). Microstructures of the samples were examined by SEM (scanning electron mi...

description | Al-Ti-C master alloy agent is currently the most promising grain refiner. This work investigates the influence of Ti(3)AlC(2) addition (1.0–3.0 wt.%) on the microstructure of a hypoeutectic cast iron (4.7 wt.% Cr, 2.3 wt.% C). Microstructures of the samples were examined by SEM (scanning electron microscope). It was demonstrated that the added Ti(3)AlC(2) did reduce the size of coarse primary carbides. The XRD (X-ray diffraction) pattern shows that Ti(3)AlC(2) is decomposed into TiC in the alloy substrate. The EDS (energy dispersive spectrometer) interfacial element analysis shows that TiC combines well with the matrix interface. As the Ti(3)AlC(2) amount was increased, the finest microstructure was achieved. When 2 wt.% Ti(3)AlC(2) was added, the wear-resistance property of the material improved and became two times harder than the former. However, when 3% Ti(3)AlC(2) was added, TiC gathered at the crystal boundary, which caused a decrease in the wear resistance of the material. |
