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.

Company (B) · “Although, our company is free to do any kind managed on recycle materials, we do not put them in trash directly or recycle”.
The above respondent highlights LFI under research received their raw materials mainly from international suppliers and partly from national suppliers (i.e., fuel).
LFI were required to import most of its raw materials from abroad to maintain the level of product quality.
Managers in LFI conform that all raw materials are inspected through purchasing process.
The stage of introducing the raw materials to the production level can be considered as the base of the manufacturing process.
