用铝及其合金制造的超高真空容器及管路的特点是无磁,放射衰减快,低温下强度、塑性优良。铝及其铝合金有优良的可加工性,能够满足各种成型、焊接等要求;它的重量轻,导热速度是不锈钢的5～6倍,并可以在不高的温度下进行真空条件下的烘烤脱气。实践证明,对用LD10锻铝制造的超高真空容器,在100℃,真空度为10~(-6)托的条件下烘烤20多个小时,可很容易地达到10~(-10)托·升/厘米~2。秒的放气速率。这一指标对于地下核爆时需要的
Made of aluminum and its alloys of ultra-high vacuum vessels and piping is characterized by non-magnetic, fast decay of radiation, low temperature strength, excellent plasticity. Aluminum and its aluminum alloy have excellent machinability, to meet a variety of molding, welding and other requirements; it’s light weight, thermal conductivity is 5 to 6 times the speed of stainless steel, and can be carried out at low temperatures under vacuum conditions Baking degassing. Practice has proved that the use of LD10 forged aluminum manufacturing ultra-high vacuum container at 100 ℃, the degree of vacuum 10 ~ (-6) under the conditions of baking more than 20 hours, can easily reach 10 ~ (-10) Torr / liter / cm ~ 2. Second deflation rate. This indicator is needed for underground nuclear explosions
