| Abstract: | A study was undertaken on deep freezing of 40Cr steel. The result showed that the deep freezing could weakened the seconday temper brittleness and could heightened the toughness of alloy constructional steel. |
| |
| Keywords: | deep freezing temper brittleness grain boundary fracture quasi-cleavage dimples impact toughness |
