INTRODUCTION 1.1. Nickel Nickel is a chemical element with atomic number 28. It is denoted by the symbol ‘Ni’ and is one of the main constituent of meteorites. It was discovered in 1751, by Axel Fredrik in Sweden. It belongs to the transition metal group and is known for its hardness and ductility. Significant chemical reactivity is exhibited by pure Nickel. Nickel in its pure or low-alloy form is used in several fields as it is highly resistant to various reducing chemicals. Nickel when annealed exhibits low hardness with good ductility and malleability. 1.1.1. Nickel 200 1.1.1.1. Metallography Nickel 200 is a solid-solution alloy with a face-centered cubic structure. Nickel 200 is 99.0% pure wrought nickel. It is known for its superior mechanical properties and resistance to corrosive environments. Some other useful properties of the alloy are its magnetic and magnetostrictive properties. Nickel 200 has high thermal and electrical conductivities. Table1.1 shows the chemical composition of Nickel 200. The anti-corrosive nature of Nickel 200 finds its use in chemical…show more content…
Visible Light Optical Microscopy Visible Light Optical Microscopy is the basic characterization methods. During this thesis work Olympus GX-57 visible light microscope was used for morphological studies. Optical images were taken at magnifications of 100X, 200X, 500X, and 1000X. The average grain size of the samples was determined by linear intercept method. 3.4.3. Scanning Electron Microscope (SEM) Scanning Electron Microscope (SEM) is considered as an important characterization technique for morphological studies owing to its high magnification and good depth of focus facilities. In my thesis work Zeiss S3400N model was used for morphology studies of samples mentioned above. The micrographs were taken in secondary electron mode at different
