ledeburite

A new coldworking die steel was developed through adjusting allowing components and heattreatment process to improve the conventional steel AISI D2 of which a lot of carbides in ledeburite offer very high wearability in combination with low impact toughness which is easy to lead D2 to break up in use and hard of forging and linear cutting.

由于莱氏体钢中含有大量的碳化物,常用的AISID2冷作磨具钢具有很高的耐磨性,但由此而易于崩裂且不易锻造及线切割加工。

The results showed that in the adjacent-weld zone of the 40 mm HSS, overheated structure and a small amount of ledeburite were found.

结果表明 ,在4 0mm的高速钢近缝区存在过热组织和少量的莱氏体 ,这是由于摩擦线速度过大和钢内碳化物偏析较为严重所致 ,退火和淬火均无法消除。

Granular procedure of eutectic carbide in modified ledeburite steel is studied and granular mechanism of eutectic carbide is discussed.

研究了变质莱氏体钢中共晶碳化物的粒化过程 ,探讨了碳化物的粒化机理。

Dynamical procedure of eutectic carbides granulation during heat treatment could be accelerated by addition of modifier containing trace elements into the ledeburite steel The eutectic carbide net was broken down at 1100℃ and could be turned into granular carbies distri buted uniformly at (1120～1130)

莱氏体钢中加入变质微量元素，可加速热处理过程中共晶碳化物粒化的动力学过程，得到良好的粒化效果，在１１００℃可达到断网，（１１２０～１１３０）℃获得均匀分布的粒状碳化物。

Through the processing, it becomes a kind of extremely hard, wear-resistant and dispersed ledeburite structure which consists of martensite, retained austenite and carbide phases.

表面层极硬、耐磨而弥散的莱氏体是由马氏体+残留奥氏体+碳化物相组成。

Large eutectic ledeburite is not found.

合金层中的碳化物细小、均匀、弥散,无粗大的共晶莱氏体组织。

It provides a scientific evidence for study on the plastic deformation of ledeburite steel and iron materials.

为莱氏体钢铁材料塑性变形的研究提供了科学的证据。
