本文采用Nikon ECLIPSE MA200光学显微镜对组织试样进行光学显微观察,其部分金相结果如文中的图1和图3所示。
图1显示了4kW-3m/min下工业纯钛TA2合金激光焊接接头的宏观形貌和取向信息。图1(a)为焊接接头的宏观照片,激光焊接接头由三部分组成:母材(BM)、热影响区(HAZ)和焊缝(FZ)。由图可知BM与HAZ边界十分清晰,较容易划分。而HAZ与FZ组织形态相似,其边界较难区分。图3为4kW-3m/min下充分热处理后工业纯钛TA2合金激光焊接接头的显微组织。如图3所示,经过充分热处理后BM和FZ区域的晶粒形貌并未受到明显影响,而HAZ中的晶粒则由不规则的锯齿状变为较规则的等轴状晶粒,并且晶粒尺寸明显变大。即充分热处理后HAZ区域的晶粒尺寸大于BM,并且该区域的晶粒形态明显不同于FZ。因此可利用充分热处理获得BM、HAZ及FZ的具体区域。
