Concentration and temperature dependences of the elastic properties of quenched Fe-Co and FeCo-2V alloys

Abstract

The elastic moduli and logarithmic decrement of Fe-Co alloys are measured over the entire concentration range upon quenching from 850°C. The temperature dependences of these properties of some of these alloys and commercial FeCo-2V permendur are also measured. The bulk modulus and the Poisson ratio are calculated, and the plasticities of the alloys are estimated at 20°C (293 K) and higher temperatures. The socalled 550°C anomaly in the temperature dependences of the properties is discussed.
