摘要
Abstract
Taking the material MA6000 used for engine turbine blade as study object,the microstructure of the inner stray grains was investigated by optical microscope,SEM and TEM.The results show that stray grains exist in the material due to the different orientation grains on both sides,this means that the deflection or torsion occurs in the gains.A large number ofβ phase appears on grain boundaries in the as-cast microstructure,and a lot of chunks carbides M7C3 precipitate during cooling.关键词
