ABSTRACT
The material design Engineer is always sandwiched between functional behavior of a component and the cost it entails. The fluctuation in cost imported resources (alloying nutrient), enhances the complexity of material engineer. This work will be a product of the similar challenge of increased landed cost of molybdenum used in rotor blade casting. Wear rates under abrasive conditions are very sensitive to the ratio of the hardness of the surface to that of the abrasive particles. This problem of reducing the cost of rotor blade in which cost factor is the main factor. We continue to design different composition of Mo & Cr and measure the wear resistance and presently we want to improve the wear resistance. The optimization of wear resistance is a challenge given and I am interested in finding a viable mechanism to reduce cost. We will design various compositions then perform the following operations on them- casting, machining hardening & wear testing. We have also founded a composition which clearly reduces cost
