British Case Iron Research Association in 1948 mixed the alloying cerium, nickel and other alloying elements to cast iron, thus resulting in nodular cast iron. Since then, a number of testing on iron cast emerges in order to result in a better quality, one of which is by adding magnesium to cast iron. Based on the result of the metallographic testing, the addition of the magnesium to the cast iron could result in nodular graphite. It is found that the nodular graphite in cast iron based on a laboratory
Grey cast iron is the most widely used foundry alloy in the world due to its wide range of achievable mechanical properties, good castability, excellent wear resistance and damping properties, high thermal conductivity as well as low cost (20-40% less than steel) (Xu et al., 2005). It is used in such diverse applications as cookware and musical instruments to auto parts and heavy machineries. Microstructure of grey cast iron is characterized by dispersion of graphite flakes in a ferrous matrix. It
Even though a gigantic iceberg caused the titanic to sink inferior materials used in the applications, wrong reverts design, and in quality irons that used in application also forced the ships to sink so quickly. (Reference: metallurgy of the RMS titanic, Tim Foecke) Materials used in the applications of the Titanic Mild steels, manganese sulfide, wrought iron are the materials used in the application of the titanic found from the researches. (References: metallurgy of the RMS titanic Tim Foecke)
this is called ore benefaction. This is when the concentrated copper gets refined. The concentrate is dried and sent into a reverberatory furnace. The minerals are partly oxidized and melted, resulting in isolated layers. The matte layer refers to the iron-copper sulfide mixture which sinks to the bottom. The slag, which refers to the remaining impurities, floats on top of the matte and the discarded. Sulfur dioxide gases are also collected and made into sulfuric acid for use in hydrometallurgical leaching
Metals are utilized in a majority of different ways, for example: gold is used to create jewelry, iron is used to create strong sturdy structures like bridges and steel is used to make long lasting items such as pots and pans. However, most metals in their natural states are less than the desired choice for the jobs they are required to do. For example, iron, although it is an incredibly strong metal in its natural form, it is delicate and rusts quite quickly in damp air
The World of Iron What is Iron? How can we use this element? There are so many needs for this element. Iron has been around since ancient times. No known person is said to have discovered it. Thinking back to early times, iron was used for many developments in the world. Also, it is a part of the Earth from the inside out. What is most important is the body’s need of iron to survive. Iron comes from the Latin word ferrum. The iron’s symbol on the periodic table is “Fe”, driven from its Latin name
transport water from higher elevations by building the aqueducts in graduated segments that allowed gravity to push the water along until it reached its destination later using them same idea in lead pipes building them under ground . Cast iron and ductile iron pipe was long and a lower costing alternative to copper before the advent of durable plastic materials but special non conductive fittings must be used where transitions are to be made to other metallic pipes, except for terminal and universal
Metal Ore An ore is any kind of rock or mineral from which a metal can be profitably extracted. Metals are rarely found uncombined (as elements) in nature. They are nearly always present in the forms of compounds, often where the metal is chemically joined with oxygen. Only the most unreactive metals, like silver and gold will be found pure. The most common metals are oxides and sulphides. Ores are rocks from which we extract metals. Metals are found naturally in rocks called ores. They
of its advantages over the other competitive materials, like light weight, providing exceptional unit strengths (strength/density ratio), high corrosion resistance, low maintenance costs, good temperature resistance (even in arctic environments), ductile, easily joined by all commercial processes such as welding, brazing, or soldering, at the last, aluminum can be easily formed by all common processes, including extrusion (a major advantage) and can be recycled. Beside of the advantages, there are
prices ranges that make it ideal. Aluminium has a lower density meaning the car will be lighter than if it was made from steel. It also doesn’t corrode easily so a car made of aluminium will last longer than that made from steel as the steel contains iron which will corrode. In saying this aluminium is much more expensive, and although it has better properties is may take the price of the car up and over the limit that is wanted for it. Steel has many great functions for a car body. It is hard and strong
Introduction The metal that I have decided to investigate is copper.This is because copper is a very versatile,in terms of properties and uses in our everyday lives.From construction pipes to electrical cables,there’s no limit to what copper can’t be used for.Fortunately Australia is resource rich in copper,as being the second largest exporter in the world.However these do come at a price,as copper can have environmental impacts and can cause irreversible damage.In this report,the properties and
Iron is an important element to the scientific community, especially those involved in the branch of chemistry. Consequently, humans rely on iron for many different things. Iron is diverse from all other elements with regards to its natural occurrence, historic and contemporary uses, the origin of its name, and when, how, where, and by whom it was discovered. It also has unique characteristic physical and chemical properties. Without the discovery, and distinctive properties of iron, life on Earth
paper will provide a detailed discussion about iron metal. The chemical, physical and mechanical properties of iron metal will be discussed. Additionally, the occurrence and major applications of the metal will also be provided. This is intended to provide an understanding of the iron metal and the chemistry around it. The geometry of coordination together with the different oxidation states will be included in the discussion. It should be noted that iron is one of the few metals that is considered
that they are generally ductile, meaning that they can be hammered thin or drawn into wires. Metals can also be liquified by heating and then resolidified by cooling. Presently metals are the strongest building materials in common use. Found in nature, metals come in the form of oxide ores, meaning they are a compound of oxygen mixed with a mineral containing a valuable constituent such as metal. Metals can also corrode and wear away by oxidation. Common metals include iron, copper, steel, tin and

Aluminium is a chemical element which is a metal, it is lustrous, ductile and non magnetic. Aluminium is also the third most abundant element on earth and the most abundant element in the earths crust. It displaces iron and steel for uses which it is better suited for and is used in an alloy with other metals i.e. copper. Timeline 16th Century - Famous Paracelsus attempts to separate “aluminous soil” which contained an
ancient times in India,china,Babylonia,Greece Egypt and rome.Where it is pre used for preparing religious objects and articles. In 13 and 14 th century some place like Byzantim venice.genoa,Florence were promonent for producing cast metals.Bronze and iron balls prepared by Russia at that times. The first foundry constructed in Mosow as a cannon Shop.Foundaries were built in during tula and other cities During the region of Ivan IV. Charcterization of metal casting
played by steel in general economic and infrastructural development, the steel industry on the other hand has often been considered as an indicative for prowess of an economy. Steel can be categorised or called an alloy that is made up of mostly irons and has carbon content with the weight ranging from 0.2% and 2.1% (C:1000–10,8.67Fe), though varies with the grade. In line with this, an alloy is said to be an incomplete or complete solid solution of a single or additional elements in a metallic
Quenching (heat treatment process): The process of heating a metal to its higher temperature and cooling it rapidly is called as quenching. Ferrous alloys after quenching produce a harder metal whereas non-ferrous alloys produce a softer than normal metal after quenching process. Effects of quenching on the structure of parental material: When carbon steel is heated above the critical temperature, the carbon diffuses into steel to form a uniform structure called Austenite. When quenching process
