Abstract |
Effect of damping coefficient on aluminium composites like B390, AZ91D, AM60B, Al6061-T6 for their damping properties using finite Element Analysis (FEA) have been greater importance in analysis of materials. Effect of alloying for their chemical, physical & mechanical properties has been studied in this paper. Various parameters such as alloy composition, ultimate tensile stress, damping coefficient and ductility of Al alloys have been clearly analyzed. It is clear from the investigation that, there is an improvement in the mechanical properties by the addition of certain alloying elements. An attempt has been made to analyze the stress distribution (Von-Misses) using ANSYS. The results for the above alloys revealed that, the stress distribution and deformation decreases in aluminium 380 alloys with damping coefficient 0.000233. In addition, ANSYS results confirm the experimental value. Aluminum (Al) die casting alloys have a specific gravity of approximately 2.7 g/cc, placing them among the lightweight structural metals [1]. The majority of die castings produced worldwide are made from aluminum alloys. Six major elements constitute the die cast aluminum alloy system: silicon, copper, magnesium iron, manganese, and zinc. Each element affects the alloy both independently and interactively. This aluminum alloy subsection presents guideline tables for chemical composition, typical properties, and dies casting, Machining and finishing characteristics for 11 aluminum die casting alloys. This data can be used in combination with design engineering tolerance guidelines for aluminum die casting and can be compared with the guidelines for other alloys in this section aim the design engineering section. The effect of Ti and Mg on the damping behavior of in situ aluminum composites damping capacity of in situ TiB2 particulate reinforced aluminum composites with Ti and Mg excess were investigated. The composites were fabricated with an exothermic reaction process via K2TiF4 and KBF4salts. The damping behavior of materials over a temperature range of 30–300 °C was investigated by using a dynamic mechanical thermal analyzer. Experimental findings indicate that the damping capacity of composites with Ti, Mg excess, respectively is lower than that of Al/5 wt. % composite when temperature is below 180 °C and is higher than of Al/5 wt.% composite above 180 °C. |
