Abstract��In order to obtain the thermal physical properties of GH4282 superalloy within 1 100 �棬 the melting point�� thermal expansion�� thermal diffusivity�� thermal conductivity�� specific heat�� elastic modulus�� shear?modulus and Poisson��s ratio were tested and analyzed by different thermal physical performance test and analysis methods. The results showed that within 1 100 �棬 with the temperature rised�� the thermal expansion coefficient�� thermal diffusivity and thermal conductivity of GH4282 superalloy increased�� but its elastic modulus and shear modulus decreased. Least?square?method was used to establish the functional relation among the linear thermal expansion�� average thermal expansion coefficient�� thermal diffusivity�� thermal conductivity�� specific heat�� elastic modulus�� shear modulus�� Possion��s ratio and temperature of GH4282 superalloy within 1 100 ��.
