Once the true stress-strain curves were developed from the data extrapolated by the tensile tester, mechanical properties of each metal were compared. 316 Stainless Steel yielded the highest toughness, tensile strength, and percent elongation. For application purposes, environments that entail high impact load, like jet engine components or heat exchangers, are suggested for 316 Stainless Steel. Additionally, as a result of the corrosion resistant properties, 316 Stainless Steel is suggested in environments

specimen - energy absorption capacity was 257.96kN-mm. It was 23.65 percent more than the energy absorption capacity of HSBC1 specimen. The term Ductility [17] is defined as the ability of structure to undergo large amount of deformations without reduction of its strength. Deflection ductility was calculated by using peak load deflection curves. Deflection ductility of Hybrid fiber reinforced high strength concrete specimen HYBC2.1 is more than the control

Copper is an element and a mineral important to our everyday lives. Because copper is stable, it can be used in jewelry, coins, wiring, and statues. It’s one of the well-known metals due to its reddish brown metallic color. Because copper has high ductility, malleability, thermal and electrical conductivity, and resistance to corrosion, it is a major industrial metal. Copper is one of the oldest metals, dating back more than 10,000 years ago. In ancient Egypt, many used everyday items created of copper

For the hull steel, the high-quality steel is better for hull steel, such as high ductility steels. The manufacturers could design a new rivet to make the body connect firmly. To avoid the effects of flooding following assumed hull damage caused by some external force, there should not be sealing off the compartments between the sixteen

Introduction Quenching is one of the most important heat treatment process to attain desirable properties, for example strength and hardness. Quenching means to rapidly cool a material. But this rapid cooling can cause some serious distortions in the material. In steels, the transformation phases and thermal gradients are the main causes of this distortion. It has become an industry objective to reduce this distortion caused by heat treatments. Ideally, controlling the quenching process by changing

Task 1 (P1) The periodic table is laid out into groups and periods. They are also put into different blocks S-Block, D-Block, P-block and F-Block due to their energy levels. They are organised by their energy levels and chemicals properties. As the elements go along the periods in the periodic table the electronegativity increases but as the elements go down the groups the electronegativity decreases. Ionizing energy also increases as the elements go across the periods and also decreases when the

Titanium was first recognized in 1791 in the iron sand (FeO.TiO2) by William Gregor, an English clergyman, and an amateur mineralogist. After that similar observation was made in 1795 by a German chemist, Martin Klaproth who analyzed a mineral rutile (TiO2) and he named the element titanium after the Titans, the powerful sons of the earth in Greek mythological [Polmer (2006)]. Titanium is the fourth gorgeous metal after aluminum, iron, and magnesium. Extraction of titanium from its ores was not developed

Molybdenum was discovered by Carl Wilhelm Scheele in 1781 (“WebElements Periodic Table”). Molybdenum’s symbol, Mo, is fairly similar to its name. Boasting atomic number 42, Molybdenum sits in group 6, period 5, and is labeled as a transition metal, generally classified just as a metal (“Royal Society of Chemistry”). Though it doesn’t have any special roles in history, it is a very important element in today’s world, and has been since the manufacturing of steel became a big business. Its current

primary interests of natural scientists are to predict and explain physical, chemical properties of stone statues, for instance, the elements, the weight, the density, the solidification, the melting point, the hardness, the conductivity, and the ductility. In order to achieve aims, they brought material entities, stone statues to the laboratory, observing them with the help of sophisticated instruments, mixing a piece of stone with certain chemical reagent. How do they deal with the differences among

The nanotechnology potentially makes the human to rendering to recent and increasing hazards due to some individual properties such as its very small size and high ratio of area to mass. Nanotechnology is the competent invention of materials and systems in nanometer length scale, and exploits the rising properties and phenomenon which have been developed in nano scale. The word “nano” means 10-9, so a nanometer is one-billionth of a meter. One description of nanoscience is the study of atoms, molecules

The first bileaflet valves were introduced in 1978. The bileaflet valve is one of the most impactful biomedical discoveries of the past 30 years. One of the main reasons why bileaflet valves were developed was to prevent calcification that was prevalent in the previous mechanical valves. Calcification occurs when calcium deposits stick to the valve flaps which hinders the movement of the valve and the ability to allow fluid to move back in the atrium or ventricle that it originally came from. The

It shows the effect of hydrogen on metal, including the loss of ductility and internal cracking, roasting, fissuring and cracking. It shows how improvements in component design can reduce corrosion. Metals are degraded by Oxidation, Erosion and stress corrosion. 1) Oxidation: Oxidation is defined as the loss

pieces of ore to be broken down into pieces small enough for the valuable metal to be removed. Metal extraction is extremely important technique because the metals inside ores have special properties such as strength, durability, malleability, and ductility. 1 Iron, copper, aluminum are a few examples of widely used metals that are commonly extracted from their ores. In this experiment, copper was extracted from one of its ores, malachite. Since the beginning of time, metals have played a vital role
