Description
本願は、2013年6月25日出願の米国特許出願第13/926,093号に従属しかつその優先権を主張する。その内容はすべてがここに参照として組み入れられる。
y=(4+5x)/(2+x) (I)
これにより、xが以下の式により定まる。
x=(2y−4)/(5−y) (II)
得られた合金構造におけるxについて解くと、当該合金が、分数又は非整数により示されるA2B4相に対する不均一分布のAB5の存在によって、無秩序であるか否かが示される。秩序システムの一例として、1となるx値は、各A2B4平板間にあるAB5平板の数が1となる秩序ある配列を示す。(一つの可能な例としての)3.24となるx値は、xに対する分数値の存在によって当該システムにおける無秩序を示す。このようにして、結晶構造に不均一分布の相を有する合金が得られる。
