Carey, R S

Work was carried out on the centrifugal creep test principle. A simple, minimum cost, dynamic creep test machine was designed and constructed. The machine's usefulness for alloy development and materials screening for the USAEC Reactor Program was evaluated. Simple sheared sheet specimens were first tested, followed by machined specimens. Operation of the machine requires attaching sheet specimens to the test fixture, which is then rotated to apply a bending force to the specimens. This force is applied as that of a uniformly loaded beam and causes a fiber stress in the sheet specimen that can be easily calculated. The stress can be varied by changing the speed of rotation. This enables stress history to be programmed into the test to simulate the stress history of a working part. These tests proved that the dynamic creep test machine is a useful screening device for metals and alloys. (auth)
