高Cr铸铁
1.
The effect of deep cryogenic treatment on the microstructure and the wear resistance of 3Cr14Mn3MoV2 hi-Cr cast iron was investigated by using X-ray diffraction,magnetic method,hardness test and wear test.
结果表明,在去稳加空冷和去稳加深冷处理过程中,随着加热温度(900～1 150℃)的升高,试样的硬度先升高后下降,并在1 000℃时达到最高值,深冷处理试样的硬度比深冷处理前明显提高,而且基本稳定在65 HRC左右;深冷处理使高Cr铸铁的残余奥氏体量大大下降,并且有二次碳化物析出,因此深冷处理使高Cr铸铁具有更高的耐磨性。
