ABSTRACT

Optimal selection of process parameters is very much essential as this is a costly process to increase production rate considerably by reducing the machining time. With the advent of newer technologies, search for new materials were started with the aim to fulfill various requirements needed in future and also search was aimed to improve material to suit the present requirements. In view for the improvement of properties of various metals and alloys (ferrous and non- ferrous), it has been seen that heat treatment is the most effective way. In this investigation studied on the mechanical properties of Aluminum alloy Al 5052 at different annealing temperature, holding time and cooling process which saw how it affects different mechanical properties such as toughness of Aluminum alloy Al 5052. An experimental investigation was carried out based on Taguchi L9 orthogonal array to analyse the sensitivity of mechanical properties attributes to the variations in process parameters such as different annealing temperature different types of cooling, with variation of holding time. Weighing factors for the output responses were determined using triangular fuzzy numbers and the most desirable factor level combinations were selected based on Grey Relation method technique.
