Gas turbines are a modern scientific/technological miracle.

The materials science of turbine blades is awesome. Most materials can't be used above about 1/2 their absolute melting temperature as they become subject to creep. But turbine blades are made with nickel and aluminum (and a carefully optimized mix of alloying elements) that just happen to form phases that become less subject to creep as they are heated (until much closer to the melting point).

The reason (as I understand it) for this is that the intermetallic phase of NiAl prevents migration of single linear dislocations; pairs of linear dislocations are needed to migrate together. But at elevated temperature these pairs dissociate from each other and migration is inhibited.
