论文《Effects of multiple post weld heat treatments on microstructure and precipitate of fine grained heat affected zone of P91 weld》被Steel Research International录用。该论文研究了多次焊后热处理（multiple post weld heat treatments，PWHTs）对P91钢焊接接头细晶热影响区（fine grained heat affected zone，FGHAZ）显微组织及碳化物的影响，结果表明PWHTs引起了FGHAZ中马氏体基体的回复及碳化物的演化，这将对P91钢焊接接头的抗蠕变性能不利。该研究成果对于P91钢在超超临界参数火力发电机组主蒸汽管道的应用具有重要指导意义。
