Optimization of Machining Parameters in Electric Discharge Machining of Al 65032
Abstract: Electric discharge machining has the potential to maintain surface topography and produce less stresses and destruction to the components. In this machining there is no contact between the tool and the work piece. The spark generated due to the electrostatic field generation between tool and the work piece. The objective of this experimentation was to create guidelines for electric discharge machining of Al 65032. Aluminum alloy 65032 is one of …

Review on Corrosion of Welded Joints
Abstract: Corrosion is one of the major problems generally faced by welded joints made from various welding processes. Welding resistance of welded joints can be improved with addition of anticorrosive elements in the base metal. However certain other factors like fabrication technique, welding practice, welding sequence, moisture contamination, organic or inorganic chemical species oxide film and scale, weld slag and spatter, incomplete weld penetration or fusion also contribute for corrosion of …

Few Aspects in Deep Drawing Process
Abstract: The process in which a punch forces a flat sheet metal blank into a die cavity is known as deep drawing. Deep Drawing (DD) is one of the sheet metal forming processes widely used in automobile, aerospace, electronics and allied industries to produce the hollow parts. Presently, the conventional deep drawing (CDD) operation is carried out at room temperature in industries. Although, CDD provides a great potential application for the …

Parametric Optimization of CNC Wire Cut EDM for Oil Harden Non-Shrinking Steel: A Comparative Study
Abstract: There has been a rapid growth in the development of harder and difficult to machine metals and newly developed alloys. Conventional machining methods are not suitable and uneconomical for such materials, thus development starts for newer concepts in metal machining. It thus plays a major role in the machining of dies, tools, etc., made of tungsten carbide, hard steel, alloys used in the aeronautics industry. It is a great concern …

Effect of Isothermal Ageing on Microstructure and Mechanical Behavior of 0.5Cr-0.5Mo-0.2V Low Alloy Steel
Abstract: Cr-Mo-V based low alloy steels are widely used in thermal power plants because of their ability to withstand elevated temperature and high pressure under continuous operation. With ferrite-pearlite and/or ferrite-bainite microstructures, these steels find their applications in boiler tubes, pressure vessels and steam turbines. Being cost effective is one of the important factors, which draws attention of many industrialists towards low alloyed steels over highly alloyed steels with austenitic matrix. …
