The Effects of Fusion Reactor Plasma Transients on the Microstructure of Eurofer 97 Steel

我的项目研究了当1.5 -2亿C的等离子体接触反应堆面向等离子体的第一壁时（例如在事故期间），聚变反应堆结构材料Eurofer 97会发生什么。我结合了有限元热分析和计算热化学模型来预测等离子体-壁相互作用的影响。我还用激光加热技术对Eurofer 97的样本进行了瞬态热暴露实验。最后，我正在探索反复等离子体-壁相互作用对新型Eurofer 97焊接技术显微结构的影响

My project studies what happens to the fusion reactor structural material Eurofer 97 when the 150-200 million C plasma contacts the plasma-facing first wall of the reactor (e.g. during an accident). I've used a combination of finite element thermal analysis and computational thermochemistry modelling to predict the effects of plasma-wall interaction. I've also conducted a transient thermal exposure experiment on samples of Eurofer 97 using a laser-heating technique. Finally, I'm exploring the effects of repeated plasma-wall interactions on the microstructure of novel Eurofer 97 welding techniques
