Cast iron

In architecture and civil engineering, sustainability plays a main role. All buildings and any construction could be potentially dangerous if they were built or designed in an inappropriate way. All structures and designs have to be safe and stable to prevent the fatal catastrophe of failing construction. The construction of any large objects, such as shopping centers, cathedrals, bridges, and other usually takes a lot of time. There are many forces that affect the designed construction and…

includes a solidification process. The metal is either atomised to a powder, or it is cast. There is several casting methods used today. Many of the methods use the mould only once, for example sand mould casting, the lost-wax method and precision casting. For larger quantities of liquid metal, there are basically two methods: ingot casting and continuous casting. Ingot casting normally uses a permanent mould made by cast iron isolated by ceramic material. There are limitations with the ingot…

for the aluminum base. The adjustment knobs are based on thousandths. When it is time to break down each machine ,the stick machine uses a flux based rod. The flux is made of a carbon based compound. The welding rods can vary from brass, copper, cast iron, and stainless steel. All of these rods are made for a different type of…

The addition of tin also improves the corrosion resistance. Iron makes the brass harder and makes the internal grain structure smaller to make proper shape of brass. Arsenic and Antimony are sometimes added to brasses that contain more than 20% zinc to inhibit corrosion. Other materials like manganese, silicon and…

HARDNESS Hardness of a material is most commonly defined as the measure of its resistance to penentration by an indenter.Hardness is also measure of strength and often has the units of stress .The indenter is often fabricated from a hard material such as diamond or hardened steel.The tips of the indenters may be conical,pyramidal,or spherical in shape.The indenter tips may also be relatively small(nano-or micro-indenters) or very large(macroindenters).Since indentation tests are relatively easy…

In steel, the presence of moisture and air, cause the Iron in steel to start oxidising and in turn forming Iron Oxide (Bayliss & Deacon 2002). This is not very effective for the intended use as vehicles are exposed to all types of weather conditions. On the other hand, the formation of an oxide on Aluminium is what allows it to be…

Castaway is a movie starring Tom Hanks as the main character, Chuck. Throughout the movie, Chuck shows again and again how important communication is to him. It starts out with him delivering packages and such for FedEx, but as a plane he had boarded crashes, he begins to face some difficult challenges. He floated to an island, survived for a long period of time, and constructed a raft to transport him across a vast amount of water to a ship where he was rescued. Four major things in Castaway…

Minerals are needed in the human body. Minerals are classified as major minerals or trace minerals. Major minerals include calcium and phosphorus. While, trace minerals include iron and zinc. Major minerals are defined as a mineral vital to health that is required in the diet in amounts more than 100 milligrams per day. Over 99% of the calcium in the human body strengthens bones and teeth. Calcium is often, found in dairy products like milk and cheese. Some secondary sources for calcium…

degree. It can be easily casted, corrosion resistant and reproduce fine detail. Moreover, it has high electrical conductivity at high temperatures. To introduce Beryllium into metals, Beryllium alloys of magnesium-aluminum, aluminum, nickel, copper, iron or cobalt are always used (Hornbostel, 1991). According to Harper (2001), Beryllium oxide, with a melting point of 2585 °C and specific gravity of 3.025, is a cubic close-packed and has a zinc blende structure. It is stable in dry…

• What is means of welding? The welding is the processes which make the permanent bonding between the two or more solid bodies o the metal if the welding is not done properly the welding joint can be brake from the welding place and if the welding is done properly the metal can be brake from the middle or the center of the object • Spot welding http://www.taylorautobody.com/Portals/16/images/Pro%20Spot%202.jpg There is many type of welding processes 1 Gas welding 2 Gas shielded arc welding 3…
