Can I Change The Colour Of My Aluminium Windows? You can choose to respray your aluminium windows any colour you want.The ideal finish for an aluminium window is a smooth, flat matt. If you choose to change the colour of your aluminium windows, be aware that it is not a permanent finish; without sealing the…
Ernest Rutherford Gold Foil Experiment Conclusion Ernest Rutherford Gold Foil Experiment In 1909, Ernest Rutherford conducted an experiment that would lead to the discovery of the existence of subatomic particles, which later became known as “Protons.” He did this by firing alpha particles at thin sheets of gold foil. Rutherford found that about half the…
JJ Thomson Plum Pudding Model Experiment JJ Thomson Plum Pudding Model The plum pudding model of the atom states that the electrons in an atom are arranged around the nucleus in a series of shells. The first shell is closest to the nucleus, with up to two electrons per orbital. Each succeeding shell has more…
Niels Bohr Atomic Model Theory Experiment Niels Bohr Education & Life Niels Bohr is a well-known Danish physicist that spent the majority of his life studying the atomic model. The atomic model is a theory that holds that the atoms in an element are different from one another and contain protons, electrons, and neutrons. Bohr’s…
Ernest Rutherford Atomic Theory Model & Experiment Ernest Rutherford Contribution Ernest Rutherford was a New Zealand-born British chemist and physicist known for his pioneering work in the study of radioactivity. In 1903, he became the first person to demonstrate that radioactive materials emit energy in a continuous stream of particles and are not merely energy…
Types of Steel and Cast Iron Test Tensile Strength Test Tensile strength is the stress required to pull apart a test piece by an axially applied load. It is performed on a machined test piece in which the middle section of the length is reduced in diameter. It is the standard test by which the…
Effect of Alloying Elements in Cast Iron Besides carbon, cast iron contains sulphur and phosphorus as impurities from the process, alloying elements such as silicon and manganese, which significantly influence the properties of the cast iron. Nickel, chromium-vanadium, copper are other metallic elements which are added in a varying amount to have specific properties. Effect…
Factors Affecting Microstructure of Cast Iron The structure of Cast iron is affected by the following factors: Carbon Content The higher the iron’s carbon content, the greater will be the tendency for it to solidify grey. To ensure that the structure is completely graphitic, the carbon content is kept less than 2 per cent when…
Alloying Elements of Steel | Alloying Elements Properties and Effects A steel composition is made up of different elements combined to form the final product. In metalwork, these elements are called alloying additions. Each alloy addition element affects steel properties differently. Depending on the desired properties, the proportion of alloying additions is added. Alloying Elements of…
Non-Ferrous Metals List | Properties of Non Ferrous Metals Non-Ferrous Metals What is Non Ferrous Metals? Non-ferrous metals can be defined as metals that do not have iron content in them. Non-ferrous metals examples include aluminum, Bronze, copper, Brass, lead, zinc and tin, silver and gold. The primary advantage of non ferrous metals over ferrous materials is their…
