Bauschinger effect in thin metal films
The Bauschinger effect in thin sputter-deposited Al and Cu films is studied by isothermally deforming the films alternately in tension and compression. Passivated films exhibit an unusual Bauschinger effect with reverse flow already occurring on unloading, while unpassivated films show little or no reverse flows when the film is fully unloaded. 2005 Acta Materialia Inc.

این مطالعه در سال 1386-87 در آزمایشگاه و مزرعه پژوهشی دانشگاه صنعتی اصفهان به منظور تعیین مناسب ترین تیمار بذری و ارزیابی اثر پرایمینگ بر روی سه رقم گلرنگ تحت سه رژیم آبیاری انجام گرفت. برخی از مطالعات اثرات سودمند پرایمینگ بذر را بر روی گیاهان مختلف بررسی کرده اند اما در حال حاضر اطلاعات کمی در مورد خصوصیات مربوط به جوانه زنی، مراحل نموی، عملکرد و خصوصیات کمی و کیفی بذور تیمار شده ژنوتیپ های م...
Strain rate dependence of yield stress and early Bauschinger effect in nanoscale aluminum films with different textures
Ultrafi ne grained (UFG) and nanocrystalline (NC) metals, unlike coarse-grained metals, often show inelastic strain recovery during unloading, which is referred to as early Bauschinger effect. Several experimental and simulation studies have focused on the microscopic origins of this unusual mechanical behavior. However, the strain rate dependence of early Bauschinger effect in UFG and NC metal...
متن کاملDistorted Reflector Antennas: Radiation Pattern Sensitivity to the Surface Distortions
The high-frequency performance of the reflector antennas is mainly limited by the surface. It has been shown that distortions on different regions of the reflector surface can have different effects on the radiation performance. In other words, degradation of the radiation pattern due to the presence of surface distortions is sensitive to the location and behavior of the surface distortion prof...
متن کاملBauschinger effect in unpassivated freestanding nanoscale metal films
We show experimentally that unpassivated freestanding nanoscale metal films, subjected to uniaxial tension, show substantial Bauschinger effect (BE) during unloading, even at large overall tensile stresses. Aluminum films (thickness 200–400 nm, grain size 200 nm) show BE at stresses as high as 150 MPa and their plastic strain after unloading is often less than 50% of the expected value. In gold...
