| Abstract |
| Temperatures around 600°C., employed in present-day
industrial turbines can by no means be the practical limit for
heat resisting materials. This called upon the chemists,
physicists and metallurgists all over the world to produce the
extra high quality metals and alloys possessing high stressrupture
values, good creep strength and damping capacity,
considerable endurance and high resistance to corrosion and
oxidation. High temperature alloys like "Nimonic 80" developed
recently from subsequent investigations are lacking in
ductility, and the fabrication of turbine blades by the usual
forging operation becomes very difficult. The designers and
manufacturers of gas turbines and jet engines have recently
considered the possibility of using ceramic materials in high
temperatures service. |
