Research Progress of Microalloyed Gold-based Materials

As a precious metal material widely used in electronic packaging，jewelry and other industries，the performance improvement of gold-based materials has always been the focus of research，and micro-alloying technology，as a new metallurgical technology that can optimize metal performance，is widely used in the application and development of precious metal materials. From the perspective of microstructure and atomic morphology，we discuss the mechanism principle of microalloying technology of gold-based materials.From the point of microstructure，the reinforcement principle of micro-alloying is expounded from the perspective of micro-organization such as solid-solute reinforcement，second-phase reinforcement and fine crystal rein-forcement.The development process and present situation of gold microalloying technology from theoretical research to application experiment are introduced in detail.The performance differences of gold-based materials under the action of different trace elements were compared comprehensively.At present，rare earth elements have both good solid-soluble reinforcement effect，second reinforcement effect and fine crystal reinforcement effect，which are the main trace elements to optimizing the performance of gold-based materials.Finally，looking forward to the application prospect and research direction of micro-alloyed gold-based materials，we should establish a scientific model that can scientifically predict the micro-form and performance of gold-based materials on the basis of more in-depth and systematic research，and obtain the best complement element type and ratio，so as to improve the research and development efficiency of new gold-based materials.
