High-Cycle Fatigue of Single-Crystal Silicon Thin Films
When subjected to alternating stresses, most materials degrade, e.g., suffer premature failure, due to a phenomenon known as fatigue. It is generally accepted that in brittle materials, such as ceramics, fatigue can only take place in toughened solids, i.e., premature fatigue failure would not be expected in materials such as single crystal silicon. The results of this study, however, appear to...

15 صفحه اولInfluence of Operating Conditions on High-cycle Fatigue Properties of High Alloyed Steel X20
In this paper, the effect of service temperature and life on high-cycle fatigue properties of base metal, steel X20 CrMoV 12-1, has been analysed. The effect of service conditions has been analysed by testing the new material and material that was in service for 116000 hours. The investigations have included determination of permanent fatigue strength at room and operating temperature. These in...
متن کاملUltra Low Cycle Fatigue of Axisymmetric Freestanding Nanoscale Gold Films
We present ultra low-cycle fatigue experiments of axisymmetric nano-crystalline gold films of nano-thickness deformed by a spherical indenter using a recently developed freestanding membrane test. Freestanding membranes of gold were centrally deflected using a spherical indenter attached to a MEMS load cell. Fabrication of the films for these experiments yielded films 100 nm thick and 500 μm in...
متن کاملHigh-cycle Fatigue in Micron-scale Structural Films of Polycrystalline Silicon: a Reaction-layer Failure Mechanism
A study has been made of high-cycle fatigue in 2-μm thick structural films of ntype, polycrystalline silicon for MEMS applications. Using an “on-chip” test structure resonating at ~40 kHz, such thin-film polysilicon is shown to display “metal-like” stress-life fatigue behavior in room air environments, with failures occurring after lives in excess of 10 cycles at stresses as low as half the fra...
