In this paper, the metal matrix composites containing 22 wt % Cr, 2.5 wt % C and 2 to 16  volume percent TiC were processed by solidifying Fe-Cr-Ti-C in which precipitation of titaniumcarbide and chromium carbide occurred. The microstructure and abrasion resistance of in-situ synthesized composites were compared with the unreinforced high chromium white cast iron (HCWCI) containing 22 w. t. % C...

Chromium carbide-based cermets are suitable for use in abrasive and corrosive environments. This work presents the fabrication of chromium by a very fast sintering process: Electric Resistance Sintering. The thermal cycle duration was less than 1 s without protective atmosphere. Two different compositions were studied: Cr3C2-25NiCr (wt%) WC-20Cr3C2-7Ni (wt%). Microstructure crystallographic pha...

Incomplete bainitic transformation during austempering treatment is mainly caused by the supersatu-ration of austenite with carbon. Such supersaturated becomes more stable and further stabi-lization led silicon alloying. Stable does not transform remains in structure as so-called residual austenite. Therefore, carbides, which are desirable a conventional struc-ture, cannot be formed carbide fre...

The effects of Cr and Ni on three different types steel with carbon ratios under constant conditions such as the welding current 120A, voltage 80V, Diameter 10 mm angle 60 degree was observed. Nickel percentage up to 0.147% Chromium 0.083% contributed affecting mechanical properties steel. Undissolved carbide particles refine austenite grain size. In presence nickel, chromium is less effective ...

Chromium-carbon films were deposited by utilizing reactive high-power impulse magnetron sputtering with different mixture ratios of ethyne and argon a constant deposition total pressure while the temperature, pulse frequency, duty cycle average power chromium cathode remain same. The microstructure chemical bonding obtained within composition compared. results show that increasing ratio, carbon...
