The intercritical region and coarse-grained region can be distinguished from the BNE and relaxation frequency.The BNE was decreased in the martensite regions and increased in the bainite regions by the post-weld heat treatment (PWHT).The change of relaxation frequency also showed similar trends,but the rate of change was less than that of BNE.steel sa508 class Topics by Science.govFatigue performance of AAR class A railroad wheel steel at ambient and elevated temperatures.DOT National Transportation Integrated Search.2005-11-05.This paper reports on tests to measure the effect of temperature on fatigue performance of railroad wheel steel.Classical stress-life (S-N) curves were developed for AAR Class B wheel steel with specimens removed fromPrevious12
