…(2) and (3) improve the strength, magnetism, elasticity, etc. of the material. When the processed material is annealed, a structure of fine crystal grains (subgrains) of about 1 μm is generated from the tangled structure of dislocations (recovery), and then a structure of crystal grains of about tens of μm is generated by the selective growth of a small number of subgrains (primary recrystallization). Furthermore, the smaller crystal grains are consumed by the larger crystal grains, and the average size of the crystal grains increases (normal crystal grain growth). … *Some of the terminology that refers to "primary recrystallization" is listed below.

…(2)と(3)によって材料の強さ,磁性,弾性などが向上する。加工した材料を焼きなますと,転位のもつれあった構造から1μm程度の微細な結晶粒(亜結晶粒)の組織が生成し(回復),次いで少数の亜結晶粒の選択的な成長によって数十μm程度の結晶粒の組織が生成する(1次再結晶)。さらに小さい結晶粒が大きい結晶粒に食われ,結晶粒の平均寸法が増大する(正常結晶粒成長)。… ※「1次再結晶」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
