The duralumin micro-base-part is produced after the turn-milling cutting experiment. 经过实际车铣加工试验,实现了微小型硬铝座体零件的完整加工。

The test shows that turning technology is a valid method for machining micro-shafts of duralumin alloy,but some few problems need furthering investigation. 试验结果表明,应用车削技术加工硬铝材料的微小型轴类零件是一种有效的办法,但还有一些问题值得研究。

A study has been made of low-cycle impact fatigue behaviours of aluminium and duralumin including cyclic stress-strain behaviour,cyclic hardening(softening) and fatigue life. 报导工业纯铝和硬铝在常规低周疲劳和低周冲击疲劳载荷下的力学行为，包括应力应变回线、循环硬（软）化及疲劳寿命等。

It's a perfect choice instead of duralumin cable trays which are more expensive.Further more, we can manufacture new models according to your requirments. 它使用方便，经久耐用，是代替相对昂贵的合金走线槽的最佳选择，深受广大用户的青睐。

On the basis of the analysis of cold extrusion process for the duralumin drive wheel,the scheme,the drawing and the blank dimension of cold extrusion were worked out. 对硬铝主动轮的冷挤压工艺进行分析,确定了冷挤压零件图和冷挤压方案及毛坯尺寸,对零件冷挤压的变形程度进行了校核,计算了挤压吨位,拟定了挤压前的毛坯处理规范,并对模具结构进行了介绍。
