中文摘要: 在0.08 kPa的真空度下于1 300 ℃采用真空铝热还原氧化镁和氧化锶的混合物8 h,自然冷却结晶后得到Mg-Sr中间合金,并采用XRD、OM、EDS等对其进行表征。结果表明,制备的Mg-Sr中间合金的微观组织不规则,主要物相为Mg17Sr2,锶的质量分数为28.42%。
Abstract:Mg-Sr intermediate alloy was prepared from mixture of MgO and SrO through vacuum reduction at 1 300 ℃ for 8 h and vacuum degree of 0.08 kPa. Mg-Sr intermediate alloy was characterized by XRD, OM, EDS etc. The results show that microstructure of Mg-Sr intermediate alloy is irregular and main phase is Mg17Sr2. The mass fraction of strontium is 28.42%.
