Description
上記の従来の処理に従って束を成形するための、束を構成する個々の板は通常、積層状態に配置された平らな板として与えられる。図1は従来の処理に従って拡散結合及び超塑性成形された後の、3つの板の束の一部を図示している。示されているように、外側の板(又は、「表面の板」)F1、F2の間の空間Sはガスによって膨張させられ、そして中間の板(又は、「内側の板」又は「中心の板」)Cは、それが外側の板F1、F2の間で互い違いの方向に拡張して束の小室を画定するように、波形又は他の非線形形状に超塑性成形される。外側の板は外側に向かって膨張するので、中間の板は外側の板に反力を及ぼす傾向があり、それによって外側の板を変形させる。この反力の効果は中間の板が接続している外側の板の変形として図1に示されている。詳細には、外側の板は平らな表面を有さず、中間の板が接続された部分の反対側の表面に、通常「マークオフ(markoff)」と呼ばれるへこみMを形成するように変形される。
