Eigene Untersuchungen,lt. Durch den Zusatz von Legierungselementen kann die Umwandlungstemperatur beeinflußt werden, wobei man α- und β-stabilisierende Legierungselemente unterscheidet; zu den α-Stabilisatoren gehören vor allem O., N., C und Al, wogegen alle übrigen gebräuchlichen Legierungsmetalle die β-Phase stabilisieren.即席演说 发表于 2025-3-23 19:24:40
