  1. Is a hard, brittle, corrosion - resistant, gray to white metallic element extracted from wolframite, scheelite, and other minerals, having the highest melting point and lowest vapor pressure of any metal

    顏色呈灰色或棕黑色,硬度高,延性強,熔點極高,常溫下不受空氣侵蝕主要用途是製造燈絲和高速切削合金鋼,各種鎢電極,也用於光學儀器,化學儀器方面。
  2. Firstly, basing on the knowledge of soft magnetic materials fabricated by the powder metallurgy ( mp ), we brought forward a new ideal about the composite powder, which is to distribute brittle metal powders ( si ) to the surface and gaps of the plastic ones ( fe ), then composite particles in which plastic metal powder is packaged by brittle ones are formed by further deformation

    基於粉末冶金制備軟磁材料的相關基礎知識,我們首先提出一種全新的粉末復合思路,即將脆性金屬粉末以不同粒度范圍分佈在塑性金屬粉末的表面和間隙中,在進一步受應力變形時,形成塑性金屬包裹脆性金屬的復合包裹體。
  3. The fractorgraphy analysis show that in the layer rich in w and mo, the feature of fracture is brittle fracture which follow the bordline of crystal. in sections rich in the felt metal, the feature of fracture is ductile fracture. in w - mo layer, the feature of fracture are brittle fracture and some ductile fracture

    斷口形貌特徵研究表明,富w區、富mo區主要為沿粒界脆性斷裂;粘結金屬發生韌性斷裂; w - mo混合區為顆粒的沿粒界脆性斷裂和粘結相的韌性斷裂的混合型斷裂;富ti區為典型的穿晶解理斷裂; mo - ti混合區以穿晶解理斷裂為主,顆粒邊界表現出準解理斷裂特徵。
  4. However the study of metal - oxide hetero - interface is relatively less because the properties of metals and oxides usually differ extremely from each other. contrary to metals, the oxides are usually very brittle, elastically stiffer, insulating and exhibit less thermal expansion and their crystal lattice constants are different from metals. moreover, the preparation of specimen of metal - oxide interface is very difficult, the observation of searching a suitable interface under the electron microscope is also a tedious work

    然而,對金屬-氧化物界面結構的研究卻相對少一些,這主要是由於金屬與氧化物之間的性質相差非常大,與金屬相反,氧化物通常很脆、絕熱、熱膨脹系數小,晶格常數也不同於金屬,有的甚至相差很大,而且,制備金屬-氧化物界面比較困難,在電子顯微鏡下全面地觀察一個合適的界面也是一項令人乏味的工作。
  5. The process of using heat and gradual cooling to soften a metal such as copper, making it less brittle and, therefore, less likely to break when it is flexed

    使用加熱和逐漸製冷的方法軟化金屬的過程,如銅。使這種金屬更堅韌些,在被彎曲的時候不容易折斷。
