A method and an apparatus for nondestructive detecting and evaluating chas in the microstructural properties of a material by employing one or more magnetostrictive transducers linked to the material by means of one or more sonic signal conductors. The magnetostrictive transducer or transducers are connected to a pulser/receiver which in turn is connected to an oscilloscope. The oscilloscope is connected to a computer which employs an algorithm to evaluate changes in the velocity of a signal transmitted to the material sample as function of time and temperature.
