In order to establish aluminum alloys as a more reliable material for machine parts, especially for sliding or rolling parts, a feasibility study on nitriding of pure aluminum by surface melting was performed.
      


The present paper has outlined the heat treatment technologies of powder hot-forged parts with high density, repressed and resintered parts with medium density and P/M rolled parts with high density surface and with porous core. Emphasis has put on a process to achieve high concentration carburization by using heterogeneous austenite carburization. Experiments have shown that carburizing temperature in a range of Ac_1-Acm, i.e. 850-920℃, and according to projects 3、4 for heterogenuous carburization,...

The present paper has outlined the heat treatment technologies of powder hot-forged parts with high density, repressed and resintered parts with medium density and P/M rolled parts with high density surface and with porous core. Emphasis has put on a process to achieve high concentration carburization by using heterogeneous austenite carburization. Experiments have shown that carburizing temperature in a range of Ac_1-Acm, i.e. 850-920℃, and according to projects 3、4 for heterogenuous carburization, for iron base structural parts containing chromium, carbon contents in carburized case can be over 2% and carbide contents can be over 50%.The carbide was uniformly distributed fine particles. The wear resistence of repressed and resintered parts, which were carburized was higher than that of 20~# steel pasts which were carbon-nitrided, by 2.22 times.

本文介绍了高密度的粉末热锻零件,中等密度的复压复烧零件以及表面密度高而心部具有一定孔隙的粉末冶金滚压零件的热处理工艺。着重提出了用不均匀奥氏体渗碳处理来实现高浓度渗碳的方法。试验表明,对含铬的铁基结构零件,其渗层表面含碳量可达2%以上,碳化物量可达50%以上;复压复烧零件经不均匀奥氏体渗碳处理后,其耐磨性比20号钢氰化处理的零件提高2.22倍。

To insure the rotation of rolled parts is the fundamental condition for building normal rolling process in cross wedge rolling. Under the same technique, there will be a most difficult area to rotating the part, it is neither in the begining nor in the stretching shaping part of the wedge, it is around the highest point of the wedge from its begining where the rolled part rotates about half a circle (θ=π). It has been demonstrated by not only practice also the formulas of rotatory condition....

确保轧件旋转条件,是建立楔横轧正常轧制过程的先决条件。在工艺条件相同的情况下,轧件旋转最困难的区域,不是楔入起始段,也不是楔展宽成形段,而是在楔入段升至最高点前后轧件旋转半周(θ=π)区域内。这不仅为实践所证明,而且导出的旋转条件公式,证明了上述结论。
