Fesi2 - based semiconductors have been studied due to its good performance, low cost and potential application in power generation using waste heat. state - of - the - art techniques such as levitation melting, rapid solidification and hot uniaxial pressing ( hup ) were used for sample preparation in the present work. the phase transformation, micro structure and transport properties of the materials have been analysed with xrd, sem / edx, raman spectroscopy as well as thermoelectric characterization
在綜合評述國內外熱電材料研究新進展的基礎上，本文以懸浮熔煉、快速凝固和單軸熱壓等制備工藝為技術特徵，以mn或al摻雜fesi _ 2基合金為研究對象，採用xrd 、 sem / eds 、 raman光譜以及材料熱電性能測試等分析表徵手段，系統研究相變過程、微觀結構特徵及其對材料熱電性能的影響。 -
The advantage of al is its applicability to non - conducting substances and also to low - melting - point metallic materials. due to the fact that the levitation capability of single - axis acoustic levitation ( saal ) is comparatively weak and its applications are mainly limited to low - density substances, this paper aims at enhancing the levitation capability of saal and realizing the containerless solidification of those materials with low melting temperature and high density
本文針對當前單軸式聲懸浮能力較弱，而且主要應用於低密度材料無容器處理的研究現狀，以提高聲懸浮能力、實現低熔點高密度材料的聲懸浮無容器凝固為主線，採用理論和實驗相結合的方法，對單軸式聲懸浮過程及其主要影響因素進行了較為系統、深入的研究，主要取得以下幾方面的研究結果。
