Mechanical Processes: Centrifugal Casting
http://mechprocesses.blogspot.com/2008/06/centrifugal-casting.html
Monday, June 2, 2008. Centrifugal casting as a category includes Centrifugal Casting, Semi-Centrifugal Casting and Centrifuging. Which can be machined away. Typical materials that can be cast with this process are iron, steel, stainless steels, and alloys of aluminum, copper and nickel. Two materials can be cast by introducing a second material during the process. Typical parts made by this process are pipes, boilers, pressure vessels, flywheels, cylinder liners and other parts th. PAID TO DO SURVEYS.

Mechanical Processes: ALUMINIUM
http://mechprocesses.blogspot.com/2008/06/aluminium.html
Sunday, June 8, 2008. Extrusion is a process used in manufacturing to fabricate parts of uniform cross-sections by squeezing the material through a high-pressure outlet. A die is used to give the desired shape to the extruded metal. While many metals are used for extrusion, aluminum is most widely used for the advantages it offers. Advantages of Aluminum Extrusion :. Flexibility of size and shapes . Thermal and electrical conductivity. One can get Aluminum extrusions in various forms and shapes comparati...

Mechanical Processes: OVERVIEW OF MECHANICAL WORKING PROCESSES
http://mechprocesses.blogspot.com/2008/06/overview-of-mechanical-working.html
Thursday, June 19, 2008. OVERVIEW OF MECHANICAL WORKING PROCESSES. It is proposed to deal with the effect of mechanical work on the structure and macro-properties of metals and to follow this with a classification of the processes used for mechanical working. Effects of Mechanical Work on Metals. During the process of shape change which accompanies mechanical working the volume of the mass remains constant and an increase in length such as in rolling is accompanied by a decrease in thickness. It is impor...

Mechanical Processes: STEEL
http://mechprocesses.blogspot.com/2008/06/steel.html
Wednesday, June 4, 2008. Steel is the common name for a large family of iron alloys which are easily malleable after the molten stage. Steels are commonly made from iron ore, coal, and limestone. When these raw materials are put into the blast furnace, the result is a "pig iron" which has a composition of iron, carbon, manganese, sulfur, phosphorus, and silicon. A strongly deoxidized steel is called "killed", and a lesser degrees of deoxidized steels are called "semikilled", "capped", and "rimmed". Conta...

Thursday, May 29, 2008. Squeeze casting as liquid-metal forging, is a process by which molten metal solidifies under pressure within closed dies positioned between the plates of a hydraulic press. The applied pressure and instant contact of the molten metal with the die surface produce a rapid heat transfer condition that yields a pore-free fine-grain casting with mechanical properties approaching those of a wrought product. The squeeze casting process is easily automated to produce near-net to n...Squee...
