从铝合金被发展用于造船至今已约60年了。在这期间,在研究和发展方面作了种种努力,以便使轻合金的性能,如机械性能、疲劳强度、使用中的耐用性及安全性得到改善。本报告是对近年来轻合金研究所在船用铝合金领域内进行的实验工作所作的评述。该领域内的研究大網旨在提高5000系合金的抗拉强度和应力腐蚀抗力,同时对材料的其它性能又无大的不良影响。
It has been about 60 years since aluminum alloy was developed for shipbuilding. During this period, efforts were made in research and development to improve the properties of light alloys such as mechanical properties, fatigue strength, durability and safety in service. This report is a review of the experimental work carried out by the Institute of Light Alloy Research in the field of marine aluminum alloys in recent years. Research networks in this area are designed to increase the tensile strength and stress corrosion resistance of 5000 Series alloys without major adverse effects on other properties of the material.
