欧美各国的航空工厂虽然生产了象 F—15和 F—16、波音747、DC—10和“协和”号等先进的军用和民用机种。但是为了追求可靠性,它们的热处理部门所采用的工艺方法一般还比较保守,设备也较陈旧。七十年代以来,由于新技术革命的冲击和新型航空材料对热处理技术和能力提出了更高的要求,同时为了降低昂贵的热处理费用从而降低航空产品制造成本,一批国外航空工厂,包括航空产品制造厂和航空材料生产厂,相继对各自的热处
Aviation factories in Europe and the United States have produced advanced military and civilian aircraft such as F-15 and F-16, Boeing 747, DC-10 and Concorde. However, in order to pursue reliability, their heat treatment department generally adopts the process method which is relatively conservative and the equipment is also outdated. Since the 1970s, due to the impact of the new technological revolution and new aeronautical materials, higher requirements have been put on heat treatment technologies and capabilities. In the meantime, in order to reduce the cost of heat treatment and reduce the manufacturing cost of aviation products, a batch of foreign aviation factories, including aviation products Manufacturing plants and aviation materials production plant, one after another on the heat
