  • Magnesium Alloy Essay

    Magnesium Alloy: Microstructure Characteristics: Fig (8) : Shows the microstructure of Magnesium alloy. Picture source: Magnesium alloys have a hexagonal lattice structure. They are the lightest of all structural metals. Magnesium alloys possess a low galling tendency as a bearing surface in conjunction with shaft hardness above 400 Brinell measurement. Magnesium alloys have a low density but stand greater column loading per unit weight and have a higher specific modulus. Magnesium alloys harden rapidly with any type of cold work, therefore they cannot extensively be formed without…

  • Titanium Alloy Essay

    AC 2.3: Explain the method of making titanium alloy and investigate how the composition and structure of metal alloys, polymers and poly-matrix composites influence the properties of the parent material. 1. Extraction process. 2. Melting process. 3. Storage process. Extraction of Titanium by Kroll process: First titanium ore Rutile (TiO2) is taken. Rutile is converted into titanium sponge by the following process: Titanium tetrachloride (TiCl4) – a colourless compound is obtained as a result…

  • Al, Alloy 1 And Elece

    time curves and self-corrosion rate of Al, Alloy 1 and Alloy 2 electrodes in 2 M NaCl electrolyte, respectively. Corrosion rates were obtained by weight loss measurements in 2 M NaCl solution after 60 min. As seen in Table 1, the corrosion rate increases in the following order: Al <Alloy 1 < Alloy 2. Fig. 2 indicates that open circuit potential of Alloy 1, 2 (especially Alloy2) is more negative than that of Al. It can be seen that the potential of the Al electrode shifts in the positive…

  • Potentiodynamic Polarisation Test Of Mg Znn-N-Zn-Xca Alloys

    (b) (a) (b) 3. 1 Potentiodynamic polarization test of Mg-Zn-RE and Mg-Zn-RE-xCa alloys Potentiodynamic polarization test in Kokubo solution was carried out to evaluate the bio-degradation behavior of Mg-Zn-RE and Mg-Zn-RE-xCa alloys. The results (Fig. 1) revealed that the corrosion potential, Ecorr of Mg-Zn-RE alloy was -1841 mV, which was more negative compared with the…

  • Phase Transformation Lab Report

    Phase transformations of two Ni-Cr alloys are explained below. One is Ni40Cr60 (Line 2) which is closer to eutectic composition and contains greater % Cr and the other alloy is Ni68Cr32 (Line 1) which contains greater % Ni. Figure 1: Ni-Cr phase Diagram [1] When Ni40Cr60 is cooled below 1450°C, Cr2Ni (orthorhombic structure) grains start precipitating from liquid solution. When the alloy is quenched from 1450°C to 1200°C the grain size increases. When temperature is reduced below 1200°C,…

  • Silicon Carbide Conclusion

    The number following the decimal point indicates whether the alloy is a casting (.0) or ingot (.1 or .2). A capital letter prefix indicates a modification to a specific alloy. Example: Alloy - A356.1 the capital A (Axxx.x) indicates a modification of alloy 356.1 the number 3 (A3xx.x) indicates Silicon plus copper and/or magnesium series. The 56 (Ax56.1) identifies the alloy within the 3xx.x series. The .1 (Axxx.1) indicates that it is a final shape of ingot. The composition, physical, mechanical…

  • Effect Of Hardness In Chemistry

    In this study, the main object is to find out the hardness change due the carbonized and non-carbonized alloys in air cool or water quench’s hardness differences. And the result showed that the carbonized with in air cool samples to compare with the normal air cool without covered carbon powder were similar, but the one covered with carbon were increased the overall hardness than the one without. On the carbonized with water quench it showed the one covered with carbon can provided more hardness…

  • Temporary Magnet Essay

    Copper is the one who is the most ductile metals. Copper is essential for a various metal alloys such as coins, thermocouples and etc. Copper is essential mostly in some living organisms as the trace dietary mineral. Copper lies below the hydrogen in the electromotive series which it is not soluble in acids with the changes in hydrogen then it will react with oxidizing acids, such as hot and nitric. (The Editors of Encyclopædia Britannica, 2018). Brass, it is also an alloy it was made by a…

  • Titanium Research Paper

    magnetic, non toxic and has good heat transfer properties. Titanium and its alloys have melting points advanced those of steels, but maximum useful temperatures for structural applications usually range from 425-540C°. Titanium has good resistance to attack by most mineral acids and chlorides [ASM]. The combination of high strength, stiffness, good toughness, low thickness, and excellent corrosion resistance, provided by various titanium alloys at very low to temperately elevated temperatures,…

  • Magnesium Research Paper

    superior formability at room temperature. The main features of ductile magnesium alloys are that they have homogeneous microstructure which is free of brittle inter-metallic particles and having uniform plastic deformation promoted by its grain size as well as its crystallographic texture \cite{hirsch2013superior}. Magnesium was even used widely in World War I and in World War II for nuclear and military aircraft applications. Later its usage in military and other applications were reduced…
