austenite structure

Studies on carbides granulation in austenite ( forged or reheated) of 45 steel through the technology of controlling cooling is carried out, and the refining or spheroidal structure of the spheroidal pearlite ( Ps) is obtained.

本文作者研究了45钢的奥氏体（锻后的或重新加热的）通过控制冷却技术，使其碳化物粒化，得到Ps型的调质或球化组织。

The results show that the hypereutectic structure, which contained alloy carbides ( Cr7C3) with the hexagonal or stripy feature and with the wavy boundary and had a martensite matrix with a small amount of austenite, performed the best abrasion resistance.

试验结果表明：堆焊合金中具有波形边界的一次六角形或条状碳化物（Cr7C3）、且基体为大量马氏体加少量奥氏体的过共晶组织抗磨料磨损性最佳；

The electronic structure of austenite of high strength and high toughness steel was investigated by the recursion method in the tight binding approximation.

在紧束缚框架下用Recursion方法计算了高强高韧钢中奥氏体相的电子结构。

The deformation increases quantity of island structure in the product of medium temperature transformation in austenite and makes it finer.

形变使奥氏体中温转变产物岛状组织数量增加，并使之细化。

The analysis of the structure and break of the minor diameter cast iron bars shows that developed primary austenite dendrites distribute in framework; With the high-power electron microscope to observe the D-type graphite between dendrites, the graphite is approximately worm-shaped or coral-shaped.

对小直径铸铁型材的组织及断裂行为分析表明：发达的初生奥氏体枝晶呈框架结构分布；枝晶间的D型石墨在高倍电镜下观察石墨的形状近似呈蠕虫状或珊瑚状。
