关于正火这个过程,Ed是这样描述他的方法:
I place it back in the forge and heat it to a dull orange temp, brush it off with a wire brush to remove scale from the first three oil quenches then heat it to a little above nonmagnetic (critical Temp) check with a magnet, then hold it in a dark area and watch as the blade cools down through critical temp. The blade will be Bright colored, slowly turn dark, then turn light again and at this point be magnetic. I check it on a magnet, and then repeat the process for a second time. Next I again heat it slightly above critical temp and place in it in 70 degree f. temperature still air and allow it to cool down to room temperature.
也就是在黑暗环境下观察色变,而且,通过临界温度下晶体相变发生的磁力变化,用磁铁检查,用磁铁是个好办法。而且他这个步骤要重复2次,最后再次加温到临界点并冷却到常温,再冰冻24小时。
以上是我这个键盘党的理解,不知正确与否。 |
