1.前言一般把金属塑性加工与铸造、焊接和粉末冶金相复合的加工过程称为复合加工。金属塑性加工本身各基本方法的复合称为复合塑性加工。上述两者统称为金属复合加工。本文将叙及以轧制为基础的复合加工枝术(见图1),即轧制与铸造、粉末冶金和焊接以及轧制与拉拔、挤压、锻压、弯曲和剪切的复合加工。发展这些复合加工过程的目的在于节能、节材、高产、优质、多品种和获得特殊用途的材料。一个复合加工过程 1. Introduction Generally, the process of metal plastic processing and casting, welding and powder metallurgy complex is called composite processing. Metal plastic processing itself as the composite of the basic methods of composite plastic processing. The two collectively referred to as metal composite processing. This article will deal with the rolling-based composite processing technology (see Figure 1), namely, rolling and casting, powder metallurgy and welding and rolling and drawing, extrusion, forging, bending and shearing compound processing. The purpose of developing these composite processes is energy saving, material saving, high yield, high quality, variety and access to special purpose materials. A complex process
