mechanism of creation of compressive residual stress by shot peening
International Journal of Fatigue, 1998Co-Authors: M Kobayashi, T. Matsui, Y MurakamiAbstract:Abstract In order to clarify the mechanism of the creation of compressive residual stress by shot peening, a static Compression Test and a dynamic impact Test using a single steel ball against a flat steel plate were carried out. In the static Compression Test, Compression residual stress was created near the center of the ball indentation mark. However, in the dynamic impact Test, tensile residual stress was created near the center of the ball indentation mark and Compression residual stress was created outside of the indentation. Furthermore, the tensile residual stress in the center of the first ball indentation mark changed to compressive stress as the density of the ball indentations surrounding the first ball indentation mark increased. Therefore, the compressive residual stress created by shot peening is considered to be the result of the superposition of residual stress produced by surrounding shots.

on simultaneous shift and capture power reduction in linear decompressor based Test Compression environment
International Test Conference, 2009Co-Authors: Qiang XuAbstract:Growing Test data volume and excessive Test power consumption in scan-based Testing are both serious concerns for the semiconductor industry. Various Test data Compression (TDC) schemes and low-power X-filling techniques were proposed to address the above problems. These methods, however, exploit the very same “don't-care” bits in the Test cubes to achieve different objectives and hence may contradict to each other. In this work, we propose a generic framework for Test power reduction in linear decompressor-based Test Compression environment, which is able to effectively reduce shift-and capture-power simultaneously. Experimental results on benchmark circuits demonstrate that our proposed techniques significantly outperform existing solutions.

on capture power aware Test data Compression for scan based Testing
International Conference on Computer Aided Design, 2008Co-Authors: Jia Li, Yubin Zhang, Yu Hu, Xiaowei Li, Qiang XuAbstract:Large Test data volume and high Test power are two of the major concerns for the industry when Testing large integrated circuits. With given Test cubes in scan-based Testing, the ldquodonpsilat-carerdquo bits can be exploited for Test data Compression and/or Test power reduction. Prior work either targets only one of these two issues or considers to reduce Test data volume and scan shift power together. In this paper, we propose a novel capture power-aware Test Compression scheme that is able to keep scan capture power under a safe limit with little loss in Test Compression ratio. Experimental results on benchmark circuits demonstrate the efficacy of the proposed approach.

surface microstructure and in vitro analysis of nanostructured akermanite ca2mgsi2o7 coating on biodegradable magnesium alloy for biomedical applications
Colloids and Surfaces B: Biointerfaces, 2014Co-Authors: Mehdi Razavi, M H Fathi, Omid Savabi, Batoul Hashemi Beni, Daryoosh Vashaee, Lobat TayebiAbstract:Magnesium (Mg) alloys, owing to their biodegradability and good mechanical properties, have potential applications as biodegradable orthopedic implants. However, several poor properties including low corrosion resistance, mechanical stability and cytocompatibility have prevented their clinical application, as these properties may result in the sudden failure of the implants during the bone healing. In this research, nanostructured akermanite (Ca2MgSi2O7) powder was coated on the AZ91 Mg alloy through electrophoretic deposition (EPD) assisted micro arc oxidation (MAO) method to modify the properties of the alloy. The surface microstructure of coating, corrosion resistance, mechanical stability and cytocompatibility of the samples were characterized with different techniques including X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), electrochemical corrosion Test, immersion Test, Compression Test and cell culture Test. The results showed that the nanostructured akermanite coating can improve the corrosion resistance, mechanical stability and cytocompatibility of the biodegradable Mg alloy making it a promising material to be used as biodegradable bone implants for orthopedic applications.
