| Abstract: | Both TEM and SEM were employed to study the grain boundaries of GH2036 super alloy. The results show that proper magnesium addition make MC in the boundary fine and spheroidal. The microalloying, which also improves the transformation of coarse MC into fine M 23 C 6 particle,strengthens the grain boundary and obviously improves the endurance life of the superalloy. |

| Keywords: | magnesium microalloying high temperature alloy precipitates in the grain boundary TEM and SEM technique |
