摘要：
The thermal diffusivity, thermal conductivity, temperature coefficient of linear expansion (TCLE), and specific heat capacity of ceramic materials of shell molds and cores for casting parts of heatresistant nickel-based alloys for gas-turbine engines (GTEs) are measured in a temperature range from 20 to 1500°C by the use of methods of laser flash, relative dilatometer with a pusher, and differential scanning calorimetry (DSC). The effect of the sample thickness, various process coatings, and environment is investigated. The composition and temperature dependences of thermal diffusivity and heat expansion are considered. © 2014 Pleiades Publishing, Ltd.
