| Abstract: | Based on the chewge of the hard metal mechanical property after neep freezing process,this articul selected the hard metal spot-raer intensitying technolgy,so that made the life of sword touger 3. 7 to 5 times. It is researching and probing into the mechanism of hard metal deep freezing prelinarily conhinal with the test. |
