  • Thermal Expansion Measurements of Insulative Materials and the Effect of the TMA Furnace Thermal Gradient (.pdf)
    The Thermomechanical Analyzer (TMA) has long been the standard means of measuring the Coefficient of Thermal Expansion (CTE) of materials. In previous work, we have demonstrated that a significant vertical thermal gradient exists within the TMA furnace when testing materials of low thermal...
  • Cantilever Bimetallic - Types of Thermal Controls, Techical Article
    These devices utilize a bimetallic element to make or break a circuit. The heart of these devices lie in the bimetallic element. This element is made from specially bonded materials that react differently under the influence of a thermal load. Cantilever Bimetallic Thermal Controls | How To Guide...
  • Controlled-expansion alloys for turbine engines
    gas-turbine engines, Thermo-Span and Pyromet CTX-909. Both alloys are precipitationhardenable and have low and relatively constant coefficients of thermal expansion over a broad temperature range. They offer good thermal fatigue resistance and similar tensile strengths at both room and elevated temperatures...
  • Evaluation of Plasma Facing Components Thermal Performance by Infrared Thermography (.pdf)
    Zirconium alloy (CuCrZr). The most critical part is the manufacture of the joint between CFC tiles. and CuCrZr alloy. The introduction of a compliant metallic joint accommodates the large mismatch in the. thermal expansion coefficient between carbon and copper. However, some thermal imperfections...
  • Pyrolytic Graphite Heat Spreader Options for High Performance Embedded Components and Systems
    coefficients of thermal expansion; low density, low weight to minimize shock loads; economical cost, near net shape, high volume capable manufacturing; and high structural strength and stiffness. Thermal challenges are driving a serious review of graphite spreader material, but not all graphites are the same...
  • Rapid parts for the long haul
    are anticipated. Additionally, the resin's low coefficient of thermal expansion helps ensure the resin keeps a tight grip on the dryer's metal grill at elevated temperatures during testing. Long-term tensile properties. Effect of postcuring and aging under different conditions at room temperature for up...
