Abstract

Eddy Current Sensor to Measure the ${\gamma}-{\alpha}$/ Transformation Ratio of Metal is Designed and Implemented. Experimental Results Regarding to Impedance Variation due to ${\gamma}-{\alpha}$ Transformation Ratio of Metal Under Room Temperature are Reported. It Was Found That the Impedance of Metal is Increased With Increasing ${\gamma}-{\alpha}$ Ratio.
