Tensile and Hardness Properties of Cast 6063 Aluminium Rods produced from Sand and Squeeze Casting Moulds

This work presents experimental analysis to determine the effect of sand and squeeze casting methods on the Tensile and Hardness properties of AA6063 Aluminium. Sand and squeeze cast moulds were fabricated and used to produce Aluminium rods. The test samples from cast rods were subjected to Tensile and Hardness tests. The results obtained showed better Tensile and Hardness properties, in the squeeze cast samples that were produced under varied pressure. The hardness of squeeze casting varied from 72.9 to 82.3Hv, while that of sand casting had 70.0Hv. Also, Ultimate Tensile Strength increased with increased pressure in squeeze castings from 178.01 to 194.04MPa and 161.97 in sand castings. Conversely, the mechanical properties of the cast products improved from those of sand casting to squeeze casting. Therefore, squeeze cast products could be used in as-cast condition in engineering applications requiring high quality parts while sand casting may be used in as-cast condition for non- engineering applications or engineering applications requiring less quality parts

NEW MATERIALS FOR THE PRODUCTION OF REPLACEABLE PARTS OF TILLAGE AGRICULTURAL MACHINERY

The analysis of results of practical application of cast replaceable details of hinged tillage agricultural machinery at operation in a number of the agricultural enterprises of the Poltava region at processing of more than 60 thousand hectares within several years is presented. Comparative data of the resource of parts made of high-strength bainitic cast iron and steel serial analogues of domestic and foreign production are given. The advantages of the method of manufacturing by casting methods in comparison with the traditional method of manufacturing by stamping. This technology allows you to easily make adjustments to the design of the cultivator legs, thus providing a new quality of tillage and pruning of the root system of weeds, which eliminates the need for herbicides. The basis of this technology is the use of composite complex modifiers made by rolling powder mixtures of plastic and brittle components with the necessary observance of the proportions of their ratio. The use of powder rolled modifiers provides the necessary properties and structure of the cast metal required for further heat treatment. It is substantiated to obtain high wear resistance of cast products due to the appearance of TRIP-effect and constant updating of wear-resistant surface layer during operation.
