- Single-crystal technology is applied to nickel alloys that are used as gas turbine blades in aerospace engines. With the aid of sketches describe how a single-crystal casting can be manufactured and explain why a single-crystal casting is likely to have superior creep resistance than a directly-solidified one. Demonstrate the application of the Ten-percent Rule by calculating the approximate tensile strength and elastic modulus in the 0° direction of a carbon-fibre reinforced polymer composite if the strength and elastic modulus in the 0' single ply are 3620 MPa and 143 GPa respectively. The lay-up sequence of the composite is [0,/+45/-45/90-],.arrow_forwardA part made of sheet steel is to be nickel plated. The part is a rectangular flat plate that is 0.075 cm thick and whose face dimensions are 14 cm by 19 cm.
