Elastic deformation of twinned microstructures
Many crystalline materials exhibit twinned microstructures, where well-defined orientation relationships define the special symmetry between different, elastically anisotropic twin variants. When such twins are subjected to external loading, additional internal stresses necessarily occur at the twin boundaries in order to maintain compatibility. These compatibility stresses are constant inside ...
متن کاملDeformation analysis in microstructures and micro-devices
The mechanical behaviors of microstructures and micro-devices have drawn the attention from researchers on materials and mechanics in recent years. To understand the rule of these behaviors, the deformation measurement techniques with micro/nanometer sensitivity and spatial resolution are required. In this paper, a micro-marker identification method is developed to measure microstructure deform...
متن کاملFabrication and Deformation of 3D Multilayered Kirigami Microstructures.
Mechanically guided 3D microassembly with controlled compressive buckling represents a promising emerging route to 3D mesostructures in a broad range of advanced materials, including single-crystalline silicon (Si), of direct relevance to microelectronic devices. During practical applications, the assembled 3D mesostructures and microdevices usually undergo external mechanical loading such as o...
متن کاملEvolution of recorded microstructures in minerals during cooling of Zarrin intrusion, evidence for dynamic deformation
The Zarrin granitoids is located in the west of Yazd block, Central Iran. Zarrin granitoids exhibit mylonitic rocks ranging from protomylonitic to mylontic. In Zarrin granitoids examples of sub-magmatic, microstructures are represented by chessboard patterns in quartz and sub-magmatic fractures in plagioclase, indicating deformation at high-temperature conditions (T > 650º C) and the presence o...
متن کاملReview on ultrafined/nanostructured magnesium alloys produced through severe plastic deformation: microstructures
A review on the microstructural evolution in magnesium alloys during severe plastic deformation waspresented. The challenges deserved to achieve ultrafine/ nanostructured magnesium were discussed.The characteristics of the processed materials are influenced by three main factors, including i)difficult processing at low temperatures, ii) high temperature processing and the occurrence ofdynamic r...
