C.S.Kortovich 利用稀土金属能吸收大量氢的能力,防止高强度钢内产生氢脆[AD-A-037355(2月,1977)]。机械性能试验表明:添加 La 及 Ce 到 AlS14340钢内并且它们的加入量范围为0.1-0.2重量%时,所生产的钢材能满足多数飞机材料质量规格的最低要求。
C.S. Kortovich utilizes the ability of rare earth metals to absorb large amounts of hydrogen to prevent hydrogen embrittlement in high-strength steels [AD-A-037355 (February, 1977)]. Mechanical tests have shown that the addition of La and Ce to AlS14340 steels with additions of 0.1-0.2% by weight produces steels that meet the minimum requirements for most aircraft material quality specifications.
