The scientific hypothesis that the student will be testing is: large steel components can be efficiently produced with high mechanical properties using high deposition rate CW-MIG WAAM combined with in process cold-work. The objectives of this research are:1. To study the metallurgical evolution of steels made by CW-MIG WAAM process, and investigate the relationship between the thermal conditions, microstructure formation and the material properties.2. To establish the range of process conditions for the CW-MIG WAAM process which deposit steels with required material properties without the need for a post build heat treatment.3. To investigate the effect of an integrated deformation process, cold work and/or hot work, on the material properties of the steels made by CW-MIG WAAM process.This project will focus on low alloy steels. Exact material types will be decided when the study starts and will align with the existing research topics from the NEWAM project.

学生将测试的科学假设是：使用高沉积速率CW-CW-WAAM结合过程冷加工，可以有效地生产具有高机械性能的大型钢部件。本研究的目的是：1.研究CW-COWWAAM工艺钢的冶金演变规律，探讨热条件、组织形成与材料性能的关系.建立CW-PWWAAM工艺的工艺条件范围，该工艺存款钢具有所需的材料性能，而不需要进行后期热处理.研究综合变形工艺，冷加工和/或热加工，对CW-DWWAAM工艺生产的钢的材料性能的影响。本项目将重点关注低合金钢。确切的材料类型将在研究开始时决定，并将与NEWAM项目的现有研究主题保持一致。
