Three orientation relationships, [001]α2 /[111]α2 /(110)α1 /(110)α2 and two low--angle grain boundaries of 5.3° and 10.6° between (110)α1 and (110)α2 The semicoherent grain botmdaries are composed of structural ledges and dislocations. It could be explained by using known martensite phase transformation relationships. Key words:  9Ni steel      orientation relationship      structure of grain boundary      Received:  18 June 1998      Service E-mail this article Add to citation manager E-mail Alert RSS （） Articles by authors URL:  https://www.ams.org.cn/EN/     OR     https://www.ams.org.cn/EN/Y1998/V34/I6/565 1Rao B V N,Thomas G .Proc Int Conf on Martensitic Transformations ,Cambridge MA:MIT Press 1979:12 2Rao B V N.
