Description
Summary:Investigation of the temperature behavior of the coefficient of tensoresistance π of the amorphous Fe 86 B 14 alloy in a temperature range from room temperature to the crystallization temperature has been carried out. It has been revealed that below the Curie temperature T C , in the interval of existence of elinvar properties, π in this alloy increases only weakly, with a temperature coefficient of 4 × 10 −4 K −1 . At T > T C , a stronger temperature increase of π is observed. An analysis performed has shown that the most probable reason of the observed temperature changes in π was a temperature-induced change in Young’s modulus of the alloy. It has been shown that during crystallization the coefficient of tensoresistance π decreases with increasing amount of crystalline phases in the alloy.
