【摘要】 用定量金相试验法研究了渗碳时形成的颗粒碳化物组织的长大。结果指出,为形成大量弥散分布的颗粒碳化物,必须在渗碳初期使碳化物大量形核。更多还原

【Abstract】 In this paper, by means of quantitative metallography, the growing of granular carbide particles during carburization was studied.It was shown that the formation of large amount of dispersively distributed granular carbides should be caused by nucleating in large amount of carbides during the initial stage of carburization.更多还原
