球化率 Spheroidization rate(中英文对照)

球化率

球化率定义：

以石墨为例。在金相检验中，通常所见到的是几种形态的石墨共存。在这种情况下，评定石墨的球化质量须用球化率来解决。

所谓球化率，是指在规定的视场内，所有石墨球化程度的综合指标。它反映该视场内所有石墨接近球状的程度。

球化分级：

国家标准根据石墨形态及其分布和球化率，将球墨铸铁石墨球化分为1-6级。球墨铸铁的力学性能在很大程度上决定于球化率。

球化率与力学性能的关系：

一般来说，在其他条件相同的情况下，球化率愈高，力学性能也高。

Spheroidization rate

Spheroidization rate definition:

Taking example for the graphite. In the metallographic examination, often see is the coexistence of several forms of graphite. In this case, spheroidization quality assessment of graphite spheroidization rate must be used to solve.

The so-called nodularity, refers to the field of view, the comprehensive index of all graphite spheroidization degree. It reflects the view of all the nearly spherical degree of graphite.

Ball grading:

According to the national standard of graphite morphology and distribution and spheroidization rate of nodular graphite cast iron ball, will be divided into 1-6 grade. The mechanical properties of nodular cast iron depends very much on the spheroidization rate.

The relationship between the ball rate and mechanical properties:

Generally speaking, in other conditions are the same, the spheroidization rate is higher, the mechanical properties of high.
