挤压极限可能与高温屈服应力有关,与表面有关,或与显微组织有关。表明,这些性能能充分简便地在挤压极限图范围内定量地表现出来。这种潜在金相工艺控制在2000,5000和7000系列的高强度结构合金中是很重要的。作者认为,本文报道的 AA6063是最普通的挤压合金。当机械性能也属于一个重要的条件,尤其是有表面缺陷、粘屑和挤压表面痕迹发生时,装饰性的外观代表了特殊的制品要求。采用 AA6063挤压试验中的试验数据,即压力条件、显微组织性能及表面缺陷、粘屑和挤压表面痕迹均可通过数学方程式表示其性能,从而,提出了极限图理论。本文介绍的极限图包括显微组织和拓朴学数据。
The extrusion limit may be related to high temperature yield stress, to the surface, or to microstructure. Show that these properties can be fully and easily quantified within the limits of the extrusion limit. This potential metallurgical process control is important in the 2000, 5000 and 7000 series of high-strength structural alloys. The authors believe that the AA6063 reported in this article is the most common extruded alloy. When mechanical properties are also an important condition, especially with surface defects, sticky debris and extruded surface marks occur, the decorative appearance represents a special product requirement. Using the experimental data in the AA6063 extrusion test, pressure conditions, microstructure and surface defects, and the traces of the crumbs and extruded surfaces can all be expressed mathematically, the limit-value theory is proposed. The limit map presented in this article includes microstructure and topological data.
