人们试图通过测量板条马氏体脆性断裂的敏感性来评估低碳Fe-Mn合金作为镍钢替代品的潜力。这些合金都是脆性的，但这并不是由于锰对铁的流动特性的任何固有影响，例如σior Kyi参数的变化。脆化最有可能的原因是典型的回火脆性效应。
An attempt has been made to assess the potential of low-carbon Fe-Mn alloys as a replacement for nickel steels, by measuring the susceptibility of lath martensites in the 4 to 10 pct Mn range to brittle fracture. The alloys were all brittle, but this was not caused by any inherent effect of manganese on the flow properties of iron, such as changes in the σiorKyparameters. The most likely cause of brittleness was found to be a classical temper brittleness effect.
