对通过共挤压方法制造不连续非中心钢增强铝的工艺进行了研究。通过此过程，可以制造半成品增强型材，以便通过锻造技术进行进一步处理。因此，将由 E295GC 组成的钢筋元件插入传统的铝坯中，并共挤压成两种不同的实心型材；长方形的挤压比为10.1:1，圆形的挤压比为4.8:1。使用的铝合金是 EN AW-6060。改变坯料温度和冲压速度，以研究它们对钢绞线内增强元件位置的影响。铣削线材后，通过名为 Optomess A250 的视频测量系统进行测量。除了绞线的后部之外，纵向元件之间的距离几乎是恒定的。对于钢元件到型材边缘的距离也观察到同样的情况。这是由于材料不均匀...
The process of manufacturing discontinuously non‐centric steel reinforced aluminum by means of co‐extrusion has been examined. By this process semi‐finished reinforced profiles can be fabricated for further treatment through forging techniques. Therefore, steel reinforcement elements consisting of E295GC were inserted into conventional aluminum billets and co‐extruded into two different solid profiles; a rectangle one by an extrusion ratio of 10.1:1 and a round one by 4.8:1. The used aluminum alloy is EN AW‐6060. The billet temperature as well as the ram speed were varied to investigate their influence on the position of the reinforcement elements inside the strand. The measurement was done by a video measurement system, called Optomess A250, after milling off the strand. The distances between the elements in longitudinal direction were nearly constant, apart from the rear part of the strand. The same was observed for the distance of the steel elements to the profile edge. This due to the inhomogeneous ma...
