Recent results show that piezoelectric materials could be one of the best option in energy conversion from mechanical energy into electrical energy.[5] M.
The larger the coupling coefficients(η) of piezoelectric materials is, the higher the efficiency of energy transformation is.

Coarse Columnar Dendrites of GH3039 Nickel-Based Alloy at Diverging Grain Boundaries During Wire and Laser Additive Manufacturing: A Phase Field Simulation Nanfu Zong1,a*, Weizhao Sun1,b , Xinghong Liang,c and Tao Jing1,d 1Key Laboratory for Advanced Materials Processing Technology, Ministry of Education, School of Materials Science and Engineering, Tsinghua University, Beijing 100084, China azongnan512712_2005@163.com, bswz16@mails.tsinghua.edu.cn, cliangxh19@mails.tsinghua.edu.cn, djingtao@mail.tsinghua.edu.cn Keywords: Wire and laser additive manufacturing, phase field simulation, interface crystallographic deflection, columnar dendrite.
However, there has been a variation in the quality of manufactured materials[11].
The epitaxial growth of columnar dendrites with different orientations has a profound influence on the final microstructure, which determine several properties of metal materials from the laser melt pool bottom to its top.
