Description
を生じさせる。構造体のある領域がより高いCTEのためにより大きな収縮を示す場合、その高及び低CTE領域間の境界に沿って機械的破断を引き起こしうる付加的な応力を生じさせる。この現象はしばしば「CTE不適合(mismatch)」として言及される。
用は、本質的に不均質な材料性を生じさせるが故に制限される。普通溶接された継ぎ目は、継ぎ目に沿って異なる微構造を生じさせる。典型的には、ベース金属に適合する充填材材料を使用する溶接はより大きいグレイン寸法(grain size)を生じさせ、これが破断に敏感である機械的により弱い継ぎ目をもたらす。溶接された継ぎ目に沿う破断を避けるためには、しばしば機械的により強い充填材材料を用いて、継ぎ目をベース材料よりも強くする。それにもかかわらず、36%Ni−Fe合金の溶接に使用されるより強い充填材材料は、普通(強度に対する合金付加物のために)ベース材料よりも大きいCTEを有し、これが極低温を必要とする条件下に破断するかもしれないCTE不適合性に帰結する。かくして、改良された継ぎ目の溶接できる36%Ni−Fe合金構造体及びこの製造並びに使用法に対するたゆまぬ必要性が現存している。
献として引用されるASTM F1684またはASTM A333/A333M明細書に定義されている。具体例において、36%Ni−Fe合金は36%のNiを、ASTM明細書に記述される量のFe及び痕跡元素と共に含んでなる。ある具体例において、36%Ni−Fe合金はASTM F1684に記述されているごとき合金UNS No.K93603を含んでなる。ある具体例において、36%Ni−Fe合金はASTM A333/A333Mに記述されるごとき合金グレード11を含んでなる。ある具体例において、36%Ni−Fe合金は表1に記述される1つまたはそれ以上の合金を含んでなる。ある具体例において、36%Ni−Fe合金は図1のプロットで示すようなCTE最小値を有する合金を含んでなる。すべての元素は重量%で表示されている。
回避する。ある具体例においては、36%Ni−Fe合金の充填材材料を使用して、36%Ni−Feプレートから形成されるシングルV接合内においてガスタングステンアーク溶接により溶接ビードを形成させる。
