碳化物是钢的基本相之一,它的大小、分布、形状以及本身的性质对钢的性能有很大的影响。近年来,对弥散强化第二相的定量计算有了很大的发展,。在定量计算中,常考虑碳化物的下列参数,即颗粒的大小、颗粒之间的距离、颗粒的形状及体积分数等。本文采用X-光小角度散射、萃取、粉末、复型和金属薄膜等方法测定了碳化物尺寸,并进行了比较。一试验材料试验钢是在30CrNi5MoV基础上,仅对铬含量作了些变动,其变动情况见表1。
Carbide is one of the basic phases of steel. Its size, distribution, shape and its own properties have a great influence on the properties of steel. In recent years, there has been a great development in the quantitative calculation of the dispersion strengthened second phase. In the quantitative calculation, the following parameters of the carbide are often taken into consideration: the size of the particles, the distance between the particles, the shape and the volume fraction of the particles, and the like. In this paper, the small size X-ray scattering, extraction, powder, complex and metal films and other methods were measured carbide size, and compared. A test material test steel is 30CrNi5MoV based on chromium content only made some changes, the changes in Table 1.
