materials for gas turbine rotor

ronqlt0UPIng ZhUonZI Coll.oo燃气透平转子材料(materials for gas tur-bine rotor)工作时由叶轮和轴构成的燃气透平转子要承受各级叶片和自身的离心力、转子弯曲的交变应力;还要承受高温以及由此引起的温度应力,并要传递扭矩。因此,透平转子的材料应在工作温度条件下,具有很高的强度和良好的韧性等。 透平轮盘和轴的工作温度低于550℃时,可采用珠光体衬热姻,例如:CrMoV或CrNIMoV钢。80年代以前,透平轮盘广泛应用这类材料。90年代以来然气透平的初温已达1300℃,透平轮盘应选用含铁较多的镍基合金,以便提高其高温强度性能。 航机改型嫩气轮机的透平轮盘广泛应用航空燃气透平中使用的多种镍基合金材料。附表示出了一些珠光体耐热钢、马氏体耐热钥、镍基合金等的转子材料和其最高使用温度范围。转子材料主要成分及使用泣度┌────┬────────┬─────────────────────────────────────┬────┐│种类 │牌号 │主要化学成分(%) │使用遇度││ │ ├─────┬──────┬─────┬─────┬─────┬──────┤ (℃) ││ │ │C │Cr │Ni │Mo │W │其它 │ │├────┼────────┼─────┼──────┼─────┼─────┼─────┼──────┼────┤│珠光体 │H·27(英) │0‘4 │3 │ │0 .8 │ │V=0 .2 │~500 ││时热钢 ├────────┼─────┼──────┼─────┼─────┼─────┼──────┼────┤│ │24CrMoVS.5(德) │0.20~0.28 │1 .2~1.5 │ │0 .5~0.6 │ │V=0 .15~0.25│500 ││ ├────────┼─────┼──────┼─────┼─────┼─────┼──────┼────┤│ │P一2(俄) │0 .22~0.29│1 .5一1.8 │ │0 .6~0.8 │ │V=0.2~0.3 │535 ││ ├────────┼─────┼──────┼─────┼─────┼─────┼──────┼────┤│ │17一22A(V)(美) │镇0 .25 │1。
