Abstract
【解決手段】 多層構造は、コア層(104)と、コア層に金属組織学的に結合された少なくとも一つのクラッド層(102)とを含んでもよい。コア層(104)および少なくとも一つのクラッド層(102)は、異なる組成を有した合金である場合がある。例えば、コア層(104)は、少なくとも一つのクラッド層(102)に比べて、対照射成長耐性および/または対照射クリープ耐性を有し、また少なくとも一つのクラッド層(102)は、コア層(104)よりも、対水素吸蔵および/または腐食に対するより高い耐性を有していてもよい。従って、燃料チャネル(400)の歪曲は減少または抑制するので、制御ブレードの動きの妨げを減少または抑制する。
