magnesium as the major alloying elements constitute a group of non heat treatable alloys (AA5XXX series) used for structural materials in automotive, aircraft and marine applications. Welding of this alloy using conventional technique leads to vaporization of Magnesium, which causes compositional changes in the weld seam [9]. Hence, to regain the Mg content (from AA5XXX series materials) FSW may be the feasible technique to overcome this…

IZOD Impact Test of Notched Polymer Introduction The IZOD impact test is a method used to determine the impact resistance of materials. The main objective of this experiment is to measure the impact strength of three specimens’ material by measuring the amount of the energy required to cause the material to fracture, using Avery Denison 6709 IZOD impact tester. Materials and Methods Apparatus: Three specimens with a machined 45° notch (V-Notch) at room temperature {Polycarbonate, Polyamide…

the above results and discussion, Knuckle joint was design for 52860 N axial load by theoretical calculation. From theoretical calculation we applied that load for analysis in NX CAD software and we obtained result for steel and cast iron G25 materials and results are shown in figures. CHAPTER: 2 TYPES OF MECHANICAL JOINT Normally, Mechanical joints are…

The SLS process uses powder materials to produce 3D solid parts from CAD file. After the CAD data is uploaded to machine computer in the Stereo lithography file format, the process of sintering starts. From figure 1, it can be observed that SLS system contains three chambers. There are…

used quite frequently in a variety of construction applications. Not only was the material found to be durable and versatile, it was also a very cost-effective solution, and so its use was quite prolific in the installation of insulation, floors, ceilings, etc. Today we know that asbestos poses a very serious health concern, and so it is no longer used in modern day construction applications. Unfortunately, this material continues to exist in many of older structures found all throughout…

Graph 3.1 shows the rate of heat transfer due to ventilation, through the window, door and wall over a period of 7 days. The total rate of heat transfer for all components are also plotted in the graph. The rate of heat loss fluctuated with respect to time for all components and recorded maximum and minimum rates at similar times. The rate of heat transfer through the door is not only the highest in values but also in variation in temperatures. A more detailed representation of the data…

Do You think synthetic diamonds are better than natural diamonds? I do and here are my reasons why. First of all synthetic diamonds are more luster like. Second of all synthetic diamonds are better for the environment. Third of all synthetic diamonds cost much less than natural diamonds. First of all synthetic diamonds are more luster like because they come from the lab. This means that they do not have the coat of dirt that the mine diamonds have. “ The diamonds that come from the mine are…

The manufacturers of sealants typically ship their products as a powder, and contractors prepare the liquid sealcoating as it is needed to complete jobs. The mixture requires adding water, additives and sand in the correct proportions if the sealant is to perform as it should. Although some people believe that sand is merely a filler that is added to reduce the amount of dry sealant needed, nothing could be further from the truth. Sand Provides Important Safety Features Sealcoating without…

Engineering with respect to the work that preceded it, and how this research should be developed further in the future.” Nowadays, cellular materials are well-known in the world, however, the relationship between dynamic load and the deformation of the lattice structure is less well-studied. Actually, lattice structures can help engineer to produce macro-scale material properties more easier. The research “Energy absorption in lattice structures in dynamics” was focusing on characterising the…

Paragraph 1 For α-Quartz, its lattice symmetry is trigonal, and for β-Quartz, its lattice symmetry is hexagonal. For α-FePO4, its space group is P3121 and thus its lattice symmetry can be inferred to be also trigonal, just like α-Quartz. Similarly, β-FePO4 space group is P6422 and its lattice symmetry can be inferred to be hexagonal, just like β-Quartz. Although the chemical structures of quartz and FePO4 are different, with quartz having a formula of SiO2, they can actually be in the same…
