Structure of high-chromium cast iron

Steel in Translation, 2012
Mathematical 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.

Thermal Stability of High-Chromium Cast Iron

Metal Science and Heat Treatment, 2002
High-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 ...

Erosion Wear Behavior of High Chromium Cast Irons

Transactions of the Indian Institute of Metals, 2023
In 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 ...

Features of phase transformations in high-chromium cast irons

Metal Science and Heat Treatment, 1983
1. In contrast to cast irons with 12–14% Cr, in cast irons with 29–30% Cr transformation by bainitic and martensitic mechanisms is prevalent. 2. With increasing content of carbon and manganese there is an increase in austenite stability in both the pearlitic and intermediate regions. 3.

High-chromium cast iron sintered of sprayed powders

Powder Metallurgy and Metal Ceramics, 2007
The paper examines basic technological characteristics of high-chromium cast iron powders resulting from gas or water melt spraying. Sintering of billets made of these powders is investigated. It is shown that Fe-Cr-Mo-Cr powder alloys can combine high hardness and thermal stability.

Specific features of hydroabrasive wear of high chromium cast irons

Physicochemical Mechanics of Materials
The fracture mechanism (wear) of high-chromium cast irons in a hydroabrasive environment was studied. The grades of cast irons for parts which require mechanical cutting were determined. It is shown that the character of hydroabrasive wear of high-chromium cast irons depends on their chemical composition, structure, properties of the environment and is

Modelling of the High-Chromium Cast Iron Surface Roughness

2020
The surface roughness is one of the functions of material machinability. In order to obtain the better results in the surface roughness, it must strive for the more ideal cutting parameters. In addition to the cutting parameters on quality of surface roughness influenced by a number of factors. This paper examines the influence of cutting parameters on

Structure and properties of high-chromium white cast irons

Metal Science and Heat Treatment, 1974
1. The highly alloyed austenite produced in the alloys investigated, especially alloys 2 and 3, is very stable. The amount of austenite can be reduced only by combined heat treatment. 2. The optimal quenching temperature for all the alloys investigated is in the range of 900–975°. 3.
