The morphologies of powder were observed by using high - resolution transmission electron microscopy ( hrtem ) ; x - ray diffraction ( xrd ) pattern was used to analyze the phases of the powder ; energy dispersive x - ray spectroscopy ( edx ) was used to analyze the component of composite powder 用高分辨電鏡觀察復(fù)合粉體的形貌,進(jìn)行電子衍射分析;用d / 3ax3b型x射線衍射儀作復(fù)合粉體的物相分析;用pv9900型能譜儀作復(fù)合粉末的成分分析。
The effect of growth parameters on the morphology , structure and chemical compositon of sic whiskers have been characterized by x - ray diffraction ( xrd ) , scanning electron microscope ( sem ) , energy dispersive x - ray spectroscopy ( eds ) and transmission electron microscope ( tem ) 運(yùn)用x射線衍射( xrd ) 、掃描電子顯微鏡( sem ) 、電子能量色散譜( eds ) 、透射電子顯微鏡( tem )等表征手段,系統(tǒng)研究了工藝參數(shù)對(duì)sic晶須形貌、結(jié)構(gòu)和化學(xué)成份的影響。
Hexadecyl hydrogen maleate ( hhm ) is a new kind of analyzer crystal for soft x - ray spectroscopy , with a large 2d spacing of 58 . 58a . hhm is hoped to give a better growth habit than octadecyl hydrogen maleate ( ohm ) , because of its shorter chain length and narrower 2d spacing . in this paper , a large hhm single crystal of dimensions 60mm x 40mm x 3mm was obtained in the benzene solution by lowing the solution temperature 馬來酸氫十六酯( hhm )是一種新型的軟x ?射線分光晶體,晶面間距2d等于58 . 58a ,與ohm (馬來酸氫十八酯)屬同一系列分光晶體,碳鏈的縮短、晶面間距的減小有望給出比ohm更好的生長(zhǎng)和結(jié)晶習(xí)性。
In succession , tini thin film is deposited on single - crystal silicon substrate using optimized parameters utilizing sputtering , and its transformation temperature ( a * ) is 72 ? indicated by dsc curve after being annealed in an ultra - high vacuum ( uhv ) chamber . in addition , the composition of the silicon - based tini film was analyzed by an energy dispersive x - ray spectroscopy ( eds ) , and the ti content in the film is approximately 51at % 按照改進(jìn)的工藝參數(shù),在單晶硅襯底上濺射-淀積了tini薄膜,并進(jìn)行了超高真空退火, dsc法測(cè)得其馬氏體逆相變峰值溫度為72 ,利用能譜分析( eds )技術(shù)測(cè)得其ti含量約為51at ,通過對(duì)非晶tini薄膜與單晶硅襯底之間的界面進(jìn)行eds及x射線衍射( xrd )分析,發(fā)現(xiàn)在用大功率( 2000w )直流磁控濺射法制備tini薄膜過程中,存在ti 、 ni與si的雙向擴(kuò)散,發(fā)生了界面反應(yīng),并有三元化合物ni _ 3ti _ 2si生成。
