推荐刀公读一下,对了解热处理很有益处。
引用一小段,是一个叫Nathan的刀匠写的
I talked to Paul about that once. The gist of it is, he will HT it however you ask him to. Some folks want the high temp temper so they don't have to worry about overheating it in post-HT grinding. The down side is it lowers edge stability and reduces corrosion resistance. It creates a larger carbide volume at the expense of a more carbon lean martensite and less free chrome. Good stuff for an extruder screw pushing GR PVC - bad stuff for a knife blade (IMO).
I tested Jim's HT against my own D2 and Bob Dozier's and found them all to be very similar in tests on cardboard, leather, and hardwood. And they are all quite a bit better than other benchmarks such as Chris Reeve's S30V and Spyderco VG10, and D2 that I heat treated to HRC 61 that had retained austenite. In that test, Jim's was actually probably the best of the three, but they were all very similar. There is no magic voo-doo. D2, when it is processed to reach it's full potential, is an excellent steel for a knife. I talked to Dozier in Atlanta this summer about his D2 (which does not include cryo) and he was very tight lipped about it. I can not achieve the results that he achieves without cryo. But my HT with cryo (and Jim's, which is the same as mine) equal it in every test. And it isn't rocket science. |
