An investigation of the stress-rupture and creep properties of hot-pressed molybdenum disilicide has produced the following results: 1. The long-time strength of molybdenum disilicide at high temperatures is superior to that of the high-temperature alloys and titanium carbide ceramals. 2. The use of molybdenum disilicide above 1800 degres F may be limited by the creep rate rather than by the stress-rupture life. 3. A comparatively convenient and satisfactory method for creep and stress-rupture testing to 2000 degrees F has been developed.
