摘要： 退火孪晶是低层错能面心立方金属材料中比较常见的一种显微组织。斑铜艺人利用“锻打”和“高温烧斑”的工艺，使晶粒发生异常长大后形成退火孪晶，制造了瑰丽斑驳的斑铜艺术品。虽然他们并不知道出现这些斑纹背后的科学原理，然而他们通过积累的生产实线经验，已经能够控制并利用退火孪晶这种显微组织。随着现代材料与冶金科学技术的发展，人们对控制材料显微组织的重要性有了更加深刻的认识，也有了更多的方法。基于退火孪晶的晶界工程研究与实践就是控制与利用退火孪晶这种显微组织的过程。

Abstract: Annealing twins is a common microstructure in face centered cubic metallic materials with low stacking fault energy. Craftsman makes speckled copper artworks by forging and high temperature heat treatment. However, they do not know the metallurgical theory behind the processing. Actually, the speckles in the copper artworks are the coarse annealing twins as a result of abnormal grain growth. With the development of modern metallurgy technique, people emphasized more on the microstructure control to obtain desired bulk properties. Twininduced grain boundary engineering is one of such technique to control and use the annealing twins.

Key words: annealing twins, copper artwork, grain boundary engineering, microstructure control
