Apr 1, 2013 · Hypereutectic high Cr cast irons (HCCIs) possess high resistance to wear, benefiting from their high volume fraction of hard carbides. However, the primary carbides are usually coarse, rendering the materials less tough and thus negatively influencing their resistance to wear, especially when impact force is involved.

May 1, 2020 · The combined effects of W, Mn and Mo additions on the microstructure and properties of a hypereutectic high chromium cast iron (HCCI) were studied. The results indicated that W was distributed uniformly in the matrix and carbides. The W and Mo addition promoted the formation of M 2 C and M 6 C carbides.

Mar 1, 2024 · A novel heterogeneous structure welded joint was developed by joining low carbon steel (LCS) with hypereutectic high-chromium white cast iron (HCWCI). The tensile strength and ductility of LCS are 470.3 MPa and 25.3%, while that of …

Dec 26, 2024 · This study focuses on developing wear-resistant multi-component hypereutectic high chromium cast irons, merging concepts of high entropy alloys with the conventional metallurgy of white cast irons, specifically exploring the influence of carbide-forming elements such as V, Mo, and Ni on solidification behavior, microstructure, and wear performance.

Oct 10, 2022 · After quenching at 1050 °C, the hardness of hypereutectic high-chromium cast iron increased significantly, but the hardness of high-silicon (1.9Si and 2.6Si) samples did not change significantly. Increasing the quenching temperature and prolonging the holding time can significantly improve the hardness of high-silicon samples.

Sep 23, 2020 · On solidification of cast irons containing over 2 wt.% carbon and other alloying elements, carbide rather than graphite, forms, which enables a silver colour (white) fracture surface, and the alloy is named as “white” cast iron [1, 2]. Formation of such carbide results in the high hardness and superior wear resistance of this type of materials.

Di妊 erential thermal analysis and microscopy were made on hypereutectic white cast iron heated at constant rates. The hypereutectic iron is graphitized further easily than the hypoeutectic iron ，

Nov 12, 2013 · In this paper, a semisolid slurry of hypereutectic high chromium cast iron (HCCI) was prepared in a metal mould by a cooling slope body method under pressure. The results indicated that the size of the primary carbide in the semisolid hypereutectic HCCI specimens becomes much finer, and there is no shrinkage porosity in the semisolid ...

Jul 1, 2011 · A hypereutectic high chromium cast iron (HCCI) is featured with high abrasion resistance and hardness, making it one of the most widely used materials in mining, minerals and cementation...

Mar 15, 2021 · High-Cr white cast iron (WCI), a Fe–Cr–C based hardfacing material that typically contains 8–35% Cr and 2–5% C, has been regularly used to improve the wear resistance of ferrous substrate materials [12]. Depending on the C and Cr contents in the filler, WCIs fall into the category of hypoeutectic, eutectic and hypereutectic compositions.
