The evaluation and selection of a turbine blade material involves several x-abilities and attributes. A designer should consider lifecycle issues as well as design and manufacturing strategies simultaneously at conceptual design stage without missing any of the information. In the proposed methodology the comparison is made between different turbine blade materials based on different x-abilities and attributes. The proposed methodology compares the materials using concurrent engineering approach and multi attribute decision making approach (MADM). In the concurrent engineering approach four x-abilities namely quality, manufacturing, environment and cost are considered. To maintain uniformity attributes considered in MADM approach are same as concurrent engineering approach. Both the methodologies show that ST12TE is the best material for turbine blade for the given set of attributes and x-abilities.
