The mechanical and physical properties of Compacted

The mechanical and physical properties of compacted graphite iron (CGI) have been studied. While it is known that CGI provides at least 70% higher tensile strength, 35% higher elastic modulus and 80% higher fatigue limits than conventional grey cast iron, the objective of this paper was to determine how the properties change with varying nodularity (graphite shape) and pearlite content.

Effects of cutting fluid with different pressures and jetting

Compacted graphite iron is one of the existing structural materials for automobile engines that is difficult to machine using the conventional machining method. This article focuses on the effects of cutting fluid with different pressures and jetting paths on machined surface integrity in the machining of compacted graphite iron.

Iron Types (page 2), Austempered Compacted

Compacted Graphite Iron retains superior vibration damping characteristics, while providing significantly improved mechanical properties over gray iron. The elastic modulus of pearlitic Cr-Mo alloyed grey iron, pearlitic CGI and ductile iron as a function of applied tensile load and temperature.

Next Generation Cummins To Get CGI Block?

Compacted graphite iron blocks also see much better wear characteristics over time than either a traditional iron block or aluminum block engines. Other benefits are the ability to cast a lighter block with similar strength characteristics as a traditional iron block engine.

Compacted Graphite Iron for Diesel Engine Cylinder Blocks

Compacted graphite iron : On solidification phenomena

An improved understanding of solidification of compacted graphite iron (CGI) is necessary to predict shrinkage related casting defects. Spheroidal graphite is not only found in ductile iron (SGI) but usually also in CGI, but its characteristics and role in this material is less understood.

Microstructure Formation During Solidification and Solid State Transformation in Compacted Graphite Iron

Compacted Graphite Iron", International Journal of Cast Metals Research, 23, No. 3, pp. 185-92. Supplement VIII – M. Knig (2009): "Compilation of Results Regarding the Influence of Alloying Elements on Microstructure and Mechanical Properties of CGI", A

Abrasive Wear of Compacted Graphite Cast Iron with

Compacted graphite iron (CGI), also called vermicular graphite iron, is the most recent member of the cast iron family since the 1940s []. The vermicular-shaped (i.e., worm shaped) graphite is usually stubby with blunt edges, giving CGI a good combination of mechanical and physical properties that fall in between gray cast iron and ductile cast iron [ 2, 3 ].

Compacted Graphite Iron: Part Two

Compacted graphite iron (CGI) along with lamellar graphite iron and spheroidal graphite iron define the three main classes of cast iron according to morphology. An important measure for assessing the application of CGI is the machinability levels and through specific studies it was concluded that CGI is much more difficult to machine than standard grey cast irons.

Thermal Conductivity of Thin Walled Compacted Graphite Iron

Compacted graphite cast iron may have a complex micro - structure, especially in a thin sections. This is due to the fact that the process of obtaining thin-walled castings is not simple, because it is associated with a wide range of cooling rates at the beginning

MACHINING OF GRAY CAST IRONS AND COMPACTED

Abstract: The aim of this paper is to compare the machinability of gray cast iron and compacted graphite iron (CGI), in terms of tool life and microstructure. Two gray cast irons with different graphite morphologies and one CGI were tested. After the tool life tests with carbide and Cubic Boron Nitride (CBN) inserts, microstructural changes on the machined surfaces was investigated and SEM
