Effect of titanium on the as-cast microstructure of hypereutectic high chromium cast iron
Materials Characterization, 2008Abstract The effect of titanium on the as-cast microstructure of a hypereutectic high-Cr cast iron containing 4.0 wt.% carbon and 20.0 wt.% chromium was investigated. With the increase of titanium concentration, the primary M7C3 carbides were refined and the volume fraction of all carbides (primary and eutectic carbide) was decreased gradually.

Microstructure and properties of modified as‐cast hypereutectic high chromium cast iron
Materialwissenschaft und Werkstofftechnik, 2022AbstractThe present work studied the effects of different modification treatments on the microstructure and mechanical properties of hypereutectic high chromium cast iron containing about 35 wt% chromium and 4.0 wt% carbon. It was found that the primary carbides in the hypereutectic high chromium cast iron were all refined to different levels after ...

Structure of high-chromium cast iron
Steel in Translation, 2012Mathematical analysis permits quantitative and qualitative assessment of the phase composition of alloys. The distribution of chemical elements over the area of the corresponding metallographic image is shown for the example of copper, which is extremely nonuniformly distributed, even within a single grain.

Manganese Influence on Chromium Distribution in High-Chromium Cast Irons
Archives of Metallurgy and Materials, 2013Abstract It is shown that chromium distribution in the metal base of high-chromium cast irons depends on manganese content. According to the X-ray micro-spectral analysis data with the increase of manganese content from 0.72 to 6.49% chromium content decreased in the near-carbide zones. At the same time chromium content in carbides increased. This

Thermal Stability of High-Chromium Cast Iron
Metal Science and Heat Treatment, 2002High-chromium cast iron (HCCI) is often used for manufacturing parts operating at a high temperature and high specific pressure, for example, for spinning tools [1] or cast rolls for hot and cold rolling [2, 3]. As a rule, castings of chromium iron have a composition close to the eutectic one, which is responsible for their low strength and impact ...

Wear resistance of high chromium—high carbon cast irons
International Journal of Cast Metals Research, 2003High chromium—high carbon experimental castings were produced using chilled moulds to study their resistance while subjected to erosive conditions. An experimental design in which the ratio of chromium over carbon equivalent, the amount of molybdenum and that of vanadium plus titanium were varied each in two different levels to obtain eight different ...

Erosion Wear Behavior of High Chromium Cast Irons
Transactions of the Indian Institute of Metals, 2023In this study, two high chromium cast irons (HCCI) with different chromium content (15%Cr and 25%Cr), in as-cast and annealed conditions (heat-treated, HT), were tested to determine the erosion wear behavior of these alloys. Erosion tests were done using a gas blast sand facility with high erodent particle velocity (90 m/s) and high erodent feed rate ...
