... the ratcheting metal will elastically deform the passivation and build up the membrane stress in the passivation. The magnitude of the membrane stress in the passivation can be very high. This is understood as follows. The interfacial shear stress τ 0 is due to the mismatch in the CTEs of the epoxy ...

... Ge-rich layer) deposited on the relaxed Si1-xGex has a compressive strain and hence is much more prone to islanding surface morphology. The undulations which can form at around 450˚C because of strain-driven surface diffusion can scatter holes and hence reduce mobility enhancements of the holes14. H ...

Superalloy
A superalloy, or high-performance alloy, is an alloy that exhibits several key characteristics: excellent mechanical strength, resistance to thermal creep deformation, good surface stability and resistance to corrosion or oxidation. The crystal structure is typically face-centered cubic austenitic. Examples of such alloys are Hastelloy, Inconel, Waspaloy, Rene alloys, Haynes alloys, Incoloy, MP98T, TMS alloys, and CMSX single crystal alloys.Superalloy development has relied heavily on both chemical and process innovations. Superalloys develop high temperature strength through solid solution strengthening. An important strengthening mechanism is precipitation strengthening which forms secondary phase precipitates such as gamma prime and carbides. Oxidation or corrosion resistance is provided by elements such as aluminium and chromium.The primary application for such alloys is in turbine engines, both aerospace and marine.
