摘　　要：研究了熔铸Ａｌ－２．８％Ｌｉ６合金管坯过程中锂的损耗及氢量的变化，由试验和计算指出：合理地选择熔铸工艺可使锂的损耗降至２％以下，合金的增氢现象由“吸湿”引起。he consumption of lithium and variation of hydrogen contents in the process of melting and casting Al-2. 8% Li alloys tube have been studied. Experimental and calculation results indicate that reasonable option for melting and casting process can decrease the consumption of isotope lithium-6 below 2%. The increase of hydrogen contents in Al-Li alloys is mainly caused by absorption of moisture.
