Abstract

The development and progress of aluminum alloy preparation technology has driven the rapid development of aluminum industry

which plays a very important role in the national economy.Based on the international patent database of Derwent Innovations Index

the development and application progress of aluminium alloy technology patent were analyzed by TDA analysis tool.The results show that the patent and core patents of aluminum alloy are mainly concentrated in Japan

USA and China etc.The development direction of aluminium alloy patent technology mainly focuses on specific alloy type

alloy product structure

and the improvement of product performance through heat treatment.In recent years

the hot research and development directions are interested in aluminum alloy coatings

alloy components complication and alloy functional diversification etc.
