…Also called Elinvar. An alloy mainly made of Fe, Ni≌36%, Cr≌12%, and Mn1-2%, which has the property that the Young's modulus is almost constant with temperature changes around room temperature (Elinvar effect). Since the Young's modulus of ordinary metals and alloys decreases with increasing temperature (temperature coefficient is about 10-4 /℃), they are not suitable for use in precision instruments or standard oscillators that utilize spring properties. … *Some of the terminology that refers to the "Elinvar effect" is listed below.

…エランバーともいう。室温付近での温度変化に対してヤング率がほぼ一定である性質(エリンバー効果)をもっている,Feを主とし,Ni≌36%,Cr≌12%,Mn1~2%の合金。普通の金属・合金はヤング率が温度上昇に伴って小さくなるので(温度係数は10-4/℃程度),ばね特性を利用する精密機器や標準の振動子への使用には不適当である。… ※「エリンバー効果」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 |
