ASSIENMENT [2] METAL FORMING REVIEW QUESTIONS 1- What are the differences between bulk deformation processes and sheet metal processes? Answer. In bulk deformation‚ the shape changes are significant‚ and the work parts have a low area-to-volume ratio. In sheet metal processes‚ the area-to-volume ratio is high. 2- Extrusion is a fundamental shaping process. Describe it. Answer. Extrusion is a compression process in which the work material is forced to flow through a die orifice‚ thereby forcing

Previously‚ Yeoh‚ & Wong (1993) reported the nutritional values of A. gangetica. Ogle et al.‚ 2001 reported the folate composition of A. gangetica. However‚ not much information on the utility of this leafy vegetable has been reported. To the best of our knowledge‚ there is no report on the optimization of polyphenols and their radical scavenging activities from the edible leaves of A. gangetica. Therefore‚ the main aim of this study is to optimize extraction conditions such as EtOH concentration

MATALLIC MENIRALS ROLL NO: 07 Metallic Minerals On an auspicious day‚ sometime around a million years ago‚ a member of the Homo habilis species stood erect and walked steadily on his two feet and his two hands became totally free. A new species – Homo erectus—began its journey on a new evolutionary track. This great change took around four million years after his ancestors – the hominids — broke free from the lineage of apes and chimpanzees. But ‚ perhaps for the next seven to eight hundred

Galvanic Corrosion in the Statue of Liberty Introduction: The Statue of liberty built by Gustav Eiffel and Frederic Bartholdi in 1886 was made of materials that consisted of a wrought iron framework with an outer cladding of copper attached by saddles of copper. It was pretty much anticipated that galvanic corrosion would occur so both of the metals were separated by an insulation known as “asbestos and shellac” insulation (Shellac is a natural resin that was widely used in the Victorian

Extractive Metallurgy Minerals are naturally occurring chemical substances in the earth’s crust obtainable by mining. Out of many minerals in which a metal may be found‚ only a few are viable to be used as sources of that metal. Such minerals are known as ores. Examples: Galena‚ PbS‚ etc. It is usually contaminated with earthly or undesired materials known as gangue. The extraction and isolation of metals from ores involve the following major steps: • Concentration of the ore‚ • Isolation of the

Every 0.1% reduction in silicon in the hot metal gives rise to 1.5 % increase in hot metal production. In the competitive scenario of today’s Iron Making hence it is necessary to reduce every bit of Silicon in hot metal to boost up furnace production and productivity.
