Nickel-based alloys are used for gas turbine blades in
aerospace engines. Briefly discuss the characteristics that
make these alloys the choice for this application.
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 moduluş in the 0° single
ply are 3620 MPa and 143 GPa respectively. The lay-up
sequence of the composite is [02/+45/-45/902]s.
