摘　　要：燃气轮机是当今乃至未来很长时间的高效能源转换与清洁利用系统的主要动力装置,其安全、高效和清洁的优势得到了很多国家的重视;然而,燃气轮机涡轮和其它透平一样,受到疲劳和蠕变问题带来的困扰。概述了近年来燃气轮机透平叶片材料的进展,综述了解决叶片材料疲劳蠕变等问题的进展,并对相关问题进行了初步展望。Gas turbine is an efficient clean energy conversion and utilization system at present and in the future for a long time. Due to safety, high efficiency and clean, gas turbine gets a lot of national attention. However, as same as steam turbine, gas turbine is subjected to fatigue and creep problems. The recent advances in the gas turbine blade materials and the researches on fatigue and creep of the turbine blade were summarized in this study, and some related problems about the gas turbine blade were also presented.
