Effect of pouring temperature on microstructure and durability of DD419 single crystal superalloy

Effect of pouring temperature on microstructure and durability of DD419 single crystal superalloy

The creep rupture properties of DD419 single crystal superalloys，fabricated at varying pouring temperatures were examined under conditions of 850 ℃/650 MPa，1050 ℃/190 MPa and 1100 ℃/130 MPa. SEM，EDS and TEM were used to analyze the microstructure and component segregation to study their effects on t...
