style="text-indent:25px">鋁合金材料是現(xiàn)代工業(yè)中應(yīng)用*****的有色金屬材料之一,隨著現(xiàn)代工業(yè)發(fā)展步伐的加快,對鋁合金性能的要求也越來越高。晶粒細(xì)化是當(dāng)前能同時(shí)提高材料的強(qiáng)度、硬度和塑韌性的一種方法,它不僅能改善材料質(zhì)量,還能提高材料的力學(xué)性能和加工工藝性能,因而受到了***的關(guān)注和應(yīng)用。目前在工業(yè)生產(chǎn)中細(xì)化晶粒的方法有很多,但是**為經(jīng)濟(jì)、有效和常用的方法是向鋁熔體中添加中間合金細(xì)化晶粒。本文是以工業(yè)純鋁、石墨粉、氟鈦酸鉀為原材料,在電弧作用下合成Al-Ti-C中間合金,通過改變原材料、電流、鋁液溫度、保溫時(shí)間、碳和鈦的加入比例這些不同實(shí)驗(yàn)條件,采用光學(xué)顯微鏡(OM)、X衍射射線(XRD)、掃描電子顯微鏡(SEM)、能譜儀(EDS)等檢測手段對Al-Ti-C中間合金微觀**和物相組成進(jìn)行研究分析,探究制備Al-Ti-C中間合金的比較好工藝參數(shù)。研究結(jié)果表明,電弧作用下合成Al-Ti-C中間合金的物相主要由α-Al、TiAl_3和TiC組成。</p><div
