【Abstract】 The continuous cooling transformation (CCT) curves of ultra\|high strength steel 25CrNiWVA and 30CrNiWVA have been measured and studied by thermal dilatometer and metallography. The measured results of the transformation point and the hardness of tested steels were basically consistent with the theoretically calculated value.更多还原
