Ni) on the Soundness of Low Carbon Steel Castings Low Carbon Steel (LCS) Low-carbon steels contain up to 0.30% C. The largest category of this class of steel is flat-rolled products (sheet or strip)‚ usually in the cold-rolled and annealed condition. The carbon content for these high-formability steels is very low‚ less than 0.10% C‚ with up to 0.4% Mn. Typical uses are in automobile body panels‚ tin plate‚ and wire products.

the concepts of Engineering materials and metallurgy in order to improve the machinability reduce the formation of burrs and to improve its wear resistance. I studied carburisation of the case hardened steel. Controlling time of carbon diffusion into the austenitic steel and maintaining the carbon content to 0.25% was a major concern since an important microstructure goal during carburisation is a stable‚ uniformly fine-grained austenite. This resulted in improved fatigue resistance and toughness

change is a threatening issue in the global. Thus‚ carbon tax is used as a tool to reduce greenhouse. The Australian Government announced initially the price of carbon tax is $23 per tone and has become a concerned issue with policy proposal makers and its significant effects on all society and economy. The report will outline some features that related to the issues and impacts of carbon tax as well as the responds of business and consumers. The carbon tax will create the big gap between the poor and

Imagine that life without green tree‚ imagine people are snatching oxygen and started to do anything they can get the oxygen. When people started to sweat‚ to breath hardly‚ to think hard what had they do for their past to the nature. It happen when deforestation occurred! By definition‚ deforestation means the cutting or removal of trees from woodlands

Our Relation to the Carbon Cycle and Earth’s Energy Budget Almost everything human’s use require a form of energy. Unfortunately‚ fossil fuel is the source of energy we use to sustain ourselves. Fossil fuels emit large quantities of greenhouse gas‚ which increases the amount of carbon in the atmosphere. Our relationship to the carbon cycle and Earth’s energy budget has multiple layers. Almost everything we use requires a form of energy. To power technology‚ we burn fossil fuels. The burning of

DUE DATE: 21/11/07 CONDUCTOR: Wissam Bardouh EFFECT OF DISSOLVED CARBON DIOXIDE (CO2) ON PH OF WATER Introduction: ((Carbon Dioxide is a greenhouse gas. It is everywhere ranging from our bodies to the atmosphere. Carbon dioxide is produced in living organisms as a result of cellular respiration (glucose + oxygen -->carbon dioxide + water + energy). It occurs in high concentrations in the tissues

Water on Carbon Dioxide Levels Problem: How does varying the type of organism (plant or animal) in the level affect the level of carbon dioxide? Background: This lab is used to test the effect the respiration rates in plants in animals and how it affects the level of carbon dioxide present in the water. Oxygen and carbon dioxide are gases that are vital to all organisms‚ whether it is given or released through that organism. Both plants and animals use oxygen and carbon dioxide for
