| 1 | Mechanical and degradation behaviour of biodegradable magnesium-zinc/hydroxyapatite composite with different powder mixing显示文摘Magnesium-based biomaterials have recently gained great attention as promising candidates for the new generation of biodegradable implants.This study investigated the mechanical performance and biodegradation behaviour of magnesium-zinc/hydroxyapatite(Mg-Zn/HA)composites fabricated by different powder mixing techniques.A single step mixing process involved mechanical alloying or mechanical milling techniques,while double step processing involved a combination of both mechanical alloying and mechanical milling.Optimum mechanical properties of the composite were observed when the powders were prepared using single step processing via mechanical alloying technique.However,Mg-Zn/HA composite fabricated through single step processing via mechanical milling technique was found to have the most desirable low degradation rate coupled with highest bioactivity.The composite achieved the lowest degradation rate of 0.039×10^−3 mm/year as measured by immersion test and 0.0230 mm/year as measured by electrochemical polarization.Ca:P ratio of the composite also slightly more than enough to aid the initial bone mineralization,that is 1:1.76,as the required Ca:P ratio for initial bone mineralization is between 1:1 and 1:1.67. | Siti Nur Hazwani Mohamad Rodzi Hussain Zuhailawati B.K.Dhindaw | 2019 | Journal of Magnesium and Alloys2019，7，4： | 5 |
| 2 | 退火和固溶处理对深冷轧1100铝合金力学性能和腐蚀性能的影响显示文摘详细研究冷轧前退火和固溶处理对1100铝合金初始组织的形成、纳米至微米级组织的形成以及力学性能和腐蚀性能的影响。在50%深冷轧前,先对样品在250℃下预退火2 h,或在540℃下预固溶处理1 h。利用X射线衍射和高分辨率透射电子显微镜技术研究加工后合金的晶粒尺寸、晶格应变和位错组态。结果表明,与预固溶处理的样品相比,预退火处理的样品具有最大的晶粒长宽比(4.43)、最小的晶粒尺寸(37.53 nm)、最高的晶格应变(9.12×10^(−3))和最高的位错密度(45.16×10^(13)m^(−2))。预退火样品的硬度、极限抗拉强度和屈服强度分别提高43.44%、24.64%和20.33%。与未经预处理的深冷轧样品相比,预退火和预固溶处理样品的耐腐蚀性更好,其中预退火样品的耐腐蚀性最好。 | S.A.ZAKARIA A.S.ANASYIDA H.ZUHAILAWATI B.K.DHINDAW N.A.JABIT A.ISMAIL | 2021 | Transactions of Nonferrous Metals Society of China2021，31，10： | 1 |
