Today, iron and steel slag is used in many fields where its unique characteristics can be put to effective use. As a result of growing environmental awareness, iron and steel slag is highly regarded as a recycled material that can reduce impacts on the environment due …
The making of cast iron begins with a coination of raw materials. Iron is rarely found in its pure form. Only meteorites contain pure iron. The iron in use for centuries is found in the coination of iron and other elements. These coinations are known as iron
Ductile cast iron round bars were prepared using alloys with carbon equivalent percentage (C.E) ranging between 4.50 % and 4.76 %. Different measurements were carried out on as – cast and heat-treated specimens. Ductile cast iron is essentially a family of

Steel - Steel - Effects of heat-treating: Adjusting the carbon content is the simplest way to change the mechanical properties of steel. Additional changes are made possible by heat-treating—for instance, by accelerating the rate of cooling through the austenite-to-ferrite transformation point, shown by the P-S-K line in the figure. (This transformation is also called the Ar1 transformation

To the Graduate Council: I am submitting herewith a thesis written by Shawn Van Dyke entitled "The History of Wrought and Cast Iron." I have examined the final electronic copy of this thesis for form and content and recommend that it be accepted in partial
Iron (Fe), derives it name from the Latin word ferrum. In its pure form iron is lustrous, silvery, soft, and ductile. However, pure iron is a poor engineering material, generally not as strong as most plastics. Cast irons are based on the Fe-C system, and the solid-state
Green strength: In the green condition, there must be adequate strength for handling In the hardened state, it must be strong enough to handle the forces of casting; therefore, the compression strength should be 100 to 300 psi (0.69 to 2.07 MPa). Permeability

Introduction To put meaning to the data and conclusions drawn in this experiment several things must be known about the materials tested and the theory behind torsion testing. The two materials tested, cast iron and mild steel, have opposing characteristics. Steel is classified as a ductile material, a ductile material is known to be able to experience very large shear forces without failing
