Recovery of Tungsten and Copper from Waste Tungsten Copper Borings
Abstract: During the last many years, the unused tungsten and copper alloy from the discarded electric and electronic equipment and industrial scraps are gathering attention as a section of waste. Because of tungsten's many diverse uses, numerous types of scrap were available for recycling by a wide variety of processes. In the present study, tungsten and copper was recovered by leaching process in ammonium hydroxide solution followed by electro winning process. …

Development of Aluminium Based Silicon Carbide Particulate Metal Matrix Composite for Cylinder Liner
Abstract: Cylinder liner is used in engine block to give a wear protective surface for piston and piston rings. Friction accounts for a loss of over 30% of the total vehicle power. Over half of that power loss can be attributed to the frictional loss between piston rings and cylinder bores. The best approach for improving power train efficiency is to reduce friction loss and the way for reducing the rolling …

Simulation of Dual Microstructure Heat Treatment Process and Residual Stresses in Gas Turbine Disc by DeformHT Software
Abstract: Gas turbine disc is one of the most vital components in advanced gas engine. In order to improve the tensile strength and fatigue strength of the disc, finer grain size is to be attained at bore area and coarser grain structure at rim area in order to resist the growth of creep. Attempts have been made by several researchers experimentally on the development of dual microstructure for Inconel-718 by heat …

Experimental Evaluation and Optimization of Dry Drilling Parameters of Stainless Steel Using Different Drill Bit
Abstract: Drilling is one of the widely used in machining processes for various purposes. Stainless steel is frequently used in automotive, aircraft and aerospace and dies or mold industries, home appliances, medical and electrical equipment, but machining of stainless steel is difficult due to high tensile strength, high ductility, low heat conductivity and high fracture toughness. The cutting temperature at drill tool-chip interface affects drill hole quality, lowers the tool life, …

A Review on an Investigation on the Effect of Immersed Medium in Friction Stir Welding of Aluminium Alloys (AA 6061-T6)
Abstract: Friction stir welding is solid state welding technology used for welding of low melting point metals such as Al, Mg and its alloys. FSW process can be controlled by different parameters like rotational speed, feed rate and welding medium. In this process, a cylindrical non-consumable tool, with a profiled probe (pin) rotating about its own axis is slowly plunged into the abutting edges of work pieces rigidly clamped to a …
