A Novel Material Used In Automotive Industry: Compacted Graphite Iron, Ajit Behera
A Novel Material Used In Automotive Industry: Compacted Graphite Iron, Ajit Behera
Ajit Behera
In recent decades, materials have been a key to increase the performance of automotive parts which leads to development of new materials. The main objective is to achieve increase in quantity and quality of automotive parts produced with optimum performance during their life cycle. Cast iron has remained a competitive material due, in part, to its low production cost. In fact, among the cast iron group, one of the alternatives is lightweight alloys, that is, compacted graphite iron (CGI). Nowadays, it is accepted that CGI can effectively reduce the total weight of an automobile by virtue of its high strength- …

Now a day materials have been a key to increase the performance of automotive parts, which point out to develop a new materials having better property. Main objective is to achieve increase in quantity and quality of automotive parts produced and for an optimum performance along their life cycle. Cast iron has remained a competitive material due to its low production cost. In fact, among the cast iron group one of alternative lightweight alloys is compacted graphite iron (CGI). Nowadays it is accepted that, CGI can effectively reduce the total weight of an automobile by virtue of its high strength- …

The Natural Composite: Spheroidal Graphite Iron, Ajit Behera
The Natural Composite: Spheroidal Graphite Iron, Ajit Behera
Ajit Behera
The conventional materials are nowadays not sufficient to cater to the variety of uses and exposure to various environments that may take place while they are put into use. Hence this leads to the development of composites, which nearly suffice the above two conditions. Composite material is a material composed of two or more distinct phases (matrix phase and reinforcing phase) and having bulk properties significantly different from those of any of the constituents. In this developing age for iron industry there is large demand for spherodial Graphite iron (S.G. Iron). S.G. Iron also known as a composite in which …
Physico-Chemical Principles Of Sixteenth Century Metallurgy, Robert E. Johnson
Physico-Chemical Principles Of Sixteenth Century Metallurgy, Robert E. Johnson
Bachelors Theses and Reports, 1928 - 1970
Following a review of sixteenth century metallurgical literature and a discussion of Gibbs free energy, this thesis discusses thermodynamic considerations of galena (PbS) reduction by iron from a lead assay of this period. The importance of fluxes in this assay is emphasized. The discussion covers both equilibrium and non-equilibrium conditions at 1100 degrees Celsius. Possible substitutes for iron are also covered.
Information from twenty-one small controlled lead assays is correlated with the thermodynamic discussion to determine the purpose of each constituent in the assay.
An Investigation Of The Sintering Of Iron-Wire Compacts, George L. Vivian
An Investigation Of The Sintering Of Iron-Wire Compacts, George L. Vivian
Bachelors Theses and Reports, 1928 - 1970
A study of the sintering of iron has been made by observing the rate of bonding of iron wires wound on iron spools. The specimens were sintered at a constant temperature of 850c in vacuum furnaces capable of producing pressures of 10-5 to 10-4 mm of mercury, and the growth of the bond between wires was observed as a function of time.
It has been concluded that the volume-diffusion mechanism is strongly operating in the sintering of iron at 850c, but in an evacuated system, the evaporation-condensation mechanism also contributes to the sintering process.
Investigation Of Inclusions In Armco Ingot Iron, Edwin J. Duncan
Investigation Of Inclusions In Armco Ingot Iron, Edwin J. Duncan
Bachelors Theses and Reports, 1928 - 1970
Various chemical and electrolytic separation methods were investigated in an attempt to separate the inclusions in Armco ingot iron. Residues obtained were X-rayed for identification purposes. The microstructures of this iron were studied with the object of determining the relative sizes, locations, and possible compositions of the inclusions.
Ferromagnetic Alloys In The System Cu-Mn-Zn, W. Michael Yim
Ferromagnetic Alloys In The System Cu-Mn-Zn, W. Michael Yim
Bachelors Theses and Reports, 1928 - 1970
The purpose of this investigation is to determine whether ferromagnetic alloys exist in the ternary system Cu-Mn-Zn analogous to the other Heusler alloys. The work in this thesis is a preliminary investigation on these alloys using a common metallographic research technique and augmented with X-ray methods.
Hot-Dip Aluminizing Of Low-Carbon Steels, Claude R. Barnes Jr.
Hot-Dip Aluminizing Of Low-Carbon Steels, Claude R. Barnes Jr.
Bachelors Theses and Reports, 1928 - 1970
In a relatively short period of sixty-five years, aluminum has grown to the rank of fifth in total weight of metals produced in the world. Throughout its short life, aluminum has been found to have excellent corrosion-resistant properties; yet only in recent years has aluminum been under consideration as a corrosion-resistant coating for iron and steel.
The Electrodeposition Of Iron-Manganese Alloys, Kenneth H. Larson
The Electrodeposition Of Iron-Manganese Alloys, Kenneth H. Larson
Bachelors Theses and Reports, 1928 - 1970
Although the alteration of properties resulting from the alloying of metals in their usual commercial forms has been extensively investigated, the field of electrodeposition of alloys is believed generally not to have received the attention that it merits.
The Corrosion Resistance Of Iron-Tin Compacts As Produced By Powder Metallurgy, Robert W. Gambill
The Corrosion Resistance Of Iron-Tin Compacts As Produced By Powder Metallurgy, Robert W. Gambill
Bachelors Theses and Reports, 1928 - 1970
The art of Powder Metallurgy deals with the preparation of metal powders and their utilization. As a more pertinent definition, the following has been suggested: "Powder Metallurgy is the art of producing metal powders and shaped objects from individual, mixed, or alloyed metal powders, with or without the inclusion of non-metallic constituents".
Hardness And Electrical Resistivity Of Copper-Iron Powder Metal Compacts, Fred A. Foyle Jr.
Hardness And Electrical Resistivity Of Copper-Iron Powder Metal Compacts, Fred A. Foyle Jr.
Bachelors Theses and Reports, 1928 - 1970
Although powder metallurgical methods have been used for years to fabricate tungsten and platinum, very little scientific data have been recorded until the beginning of this century. A large percentage of all commercial production at present is based upon past practice rather than upon scientific knowledge.
Electrolytic Deposition Of Iron, Irving M. Kenoffel
Electrolytic Deposition Of Iron, Irving M. Kenoffel
Bachelors Theses and Reports, 1928 - 1970
In this thesis the purpose was to obtain a good iron deposit from a relatively simple bath. The deposit was to be of good nature and low in Carbon content. Also included is a summary of the uses to which electrolytic iron can be put as well as a summary of work done by other researchers in depositing iron electrolytically.
Some Preliminary Investiagtions Of The Magnetic Permeabilities Of Alloys Of The Ferromagnetic Metals, John H. Gambill Jr.
Some Preliminary Investiagtions Of The Magnetic Permeabilities Of Alloys Of The Ferromagnetic Metals, John H. Gambill Jr.
Bachelors Theses and Reports, 1928 - 1970
The problem presented for this thesis was an investigation of the magnetic properties of the alloys produced by the methods of powder metallurgy. The question behind this was the correlation of the magnetic properties with the bonding properties and with the diffusion of the constituents.
