摘要:
The microstructure and microhardness of Ni-base superalloy IN-738LC fabricated by laser solid forming (LSF) with the preheating was investigated. The results showed that with the increase of the preheating temperature (T-0) (25 degrees C, 800 degrees C, 900 degrees C and 1050 degrees C), the total crack length decreased significantly, the segregation of Ti and Al worsened, and the volume fraction of equiaxed grain increased, as well as the size of blocky carbides, gamma-gamma' eutectic and gamma ...More
