摘要： 研究汽轮机低压焊接转子用30Cr2Ni4MoV耐热钢贝氏体焊缝多层多道焊韧性薄弱环节及其影响因素。采用冲击韧度试验评价焊缝的整体性能，并设计裂纹沿埋弧焊焊缝的准静态韧性试验，观察裂纹的扩展方式，利用能谱分析焊缝微区成分。冲击韧度试验表明，焊缝室温冲击吸收功为118 J，焊缝整体韧性良好。焊缝准静态韧性试验研究发现，裂纹在焊缝层间不完全相变区发生失稳扩展，为焊缝韧性相对薄弱的环节。通过光学显微镜观察高温苦味酸水溶液腐蚀的试样发现，焊缝层间不完全相变区存在大量的黑色线条，裂纹的失稳扩展沿黑色线条进行。借助扫描电镜和能谱分析发现，黑色线条处的碳的质量分数明显高于基体部分，推测这些局部富碳区含有较多的对韧性不利的组织，是造成层间韧…

本研究では相分離の連続相構造に注目し，卵白連続相（C/P) ·両連続相（C||P) ·寒天連続相（P/C）の異なる3種類の連続相構造にさらに油を添加した相分離構造（o/w (C/P），o/w (C||P），o/w (P/C））とその破断特性の関係を明らかにすることを目的とした．全てのゲルにおいて，油相-水相界面には卵白の凝集ネットワークが存在していた．また，油は分散相中には存在せず，油滴として連続相中に分散相（o/w）として存在した．卵白連続相構造（o/w (C/P））では，油滴は卵白リッチ相に存在し，アクティブフィラーとして働いたため，ゲルの力学的強度が増加した．一方で，寒天連続相構造（o/w (P/C））では，油滴がインアクテ…
