本文采用两种X-ray新方法对高铬白口铸铁经不同形式的磨料磨损后的残余奥氏体量及其沿层深分布梯度进行了精确测定,结果表明,这两种方法用于高铬铸铁的研究是成功的. In this paper, two new X-ray methods were used to accurately measure the amount of retained austenite after high-chill white cast iron was worn by different forms of abrasives and its distribution along the depth of the bed. The results show that these two methods are suitable for high Research on chrome cast iron has been successful.
