N/A The microstructural changes with pearlite formation heat treatment in eutectoid steel(railway steel) consisting of only pearlite structure were evaluated by the ultrasonic attenuation and velocity measurements. The result of this investigation showed a strong linear dependence of ultrasonic attenuation on pearlite interlamellar spacing, and accordingly on fracture strength of the pearlite.
