1420CZ铝锂合金型材表面黑白斑点问题的研究

Research on Black and White Spots Problems for 1420CZ Al-Li Alloy Profile Surface

分析了1420CZ铝锂合金型材黑白斑点的组织形貌以及产生黑白斑点的机理和产生黑白斑点的关键工序。实验表明,通过调整产生黑白斑点的关键工序的相应制度,可以减少甚至控制黑白斑点的产生。

Morphology and mechanism for black and white spots of 1420CZ Al-Li alloy extrusion profiles were analyzed as well as the key processes in which black and white spots occurred; the corresponding system of key processes in which black and white spots occurred can be adjusted to reduce or even control the black and white spots.
