这项工作可以被认为是对激光钎焊连接钨基合金与低活化铁素体-马氏体钢（Eurofer）的潜力的初步评估。研究了以55 Ni-45 Ti合金为钎料，高功率半导体激光器（HPDL）为电源的钨合金与EUROFER合金的钎焊。钎焊接头显示出凝固池具有良好的表面外观和与两个母片的高度润湿性，这可能是因为钛的活性作用。研究了冶金钎焊性，并进行了纳米压痕测量，以评估与稀释现象相关的局部硬化和刚度效应。
This work can be considered as a preliminary evaluation of the potential of laser brazing for joining tungsten based alloys to reduced activation ferritic–martensitic steels (Eurofer). Brazing of tungsten and EUROFER alloys using a 55Ni–45Ti alloy as a brazer and a high power diode laser (HPDL) as a power source has been investigated. The brazed joints showed solidified pools with good superficial aspect and a high degree of wettability with the both parent sheets, presumably because of the active effect of titanium. Metallurgical brazeability was investigated and nanoindentation measurements were done to evaluate local hardening and stiffness effects associated to dilution phenomena.
