Aerospace High-temperature Mechanical Properties Testing Services

Aerospace high-temperature mechanical properties testing encompasses a suite of specialized analytical techniques designed to characterize the mechanical behavior of materials and components under elevated temperature conditions that simulate the extreme operational environments of aerospace systems. These environments include the sustained high temperatures (up to 1600°C and beyond) experienced by jet engine turbine blades, the cyclic thermal stress of spacecraft re-entry vehicles, and the combined high-heat and dynamic load conditions of hypersonic vehicle structures. Unlike ambient-temperature mechanical testing, this specialized field focuses on quantifying temperature-induced variations in material performance, including strength degradation, creep deformation, fatigue resistance, and fracture behavior, which directly govern the reliability and service life of aerospace materials. The core objective of such testing is to generate precise, reproducible data that supports the development of advanced materials—from nickel-based superalloys to ceramic matrix composites (CMCs)—by elucidating their performance limits under thermomechanical loading scenarios relevant to aerospace research.

Types of Our Services

High-Temperature Tensile and Compression Testing

Our high-temperature tensile and compression testing services quantify key mechanical parameters—including yield strength, ultimate tensile strength, elongation at break, and compressive modulus—across a temperature range of 25°C to 1500°C. Specimens are mounted in water-cooled grips to prevent thermal degradation of testing fixtures, and tests are conducted in controlled atmospheres (argon, nitrogen, or air) to simulate relevant environmental conditions. For example, we perform tensile testing on titanium alloy TA15 at 600°C to evaluate its suitability for compressor blade applications, measuring elongation at break and yield strength to assess structural integrity under sustained mid-temperature loading. This service also includes biaxial tensile testing for anisotropic materials like CMCs, which exhibit direction-dependent mechanical properties critical to their performance in aerospace structures.

Creep, Stress Rupture, and Fatigue Testing

We specialize in long-duration creep and stress rupture testing, which evaluates time-dependent deformation under constant high-temperature and stress conditions—essential for predicting the service life of engine components like turbine disks and combustor liners. Our testing systems maintain precise temperature control (±1°C) and load stability for durations up to 10,000 hours, generating creep curves that quantify primary, secondary, and tertiary creep phases. For thermomechanical fatigue testing, we simulate cyclic heating-cooling (from -50°C to 1200°C) combined with axial or torsional loading, replicating the operational cycles of aerospace components. We also conduct high-cycle fatigue (HCF) and low-cycle fatigue (LCF) testing at elevated temperatures, generating S-N curves that define fatigue life under varying stress amplitudes. A notable application of this service is the evaluation of TiAl intermetallic compounds for lightweight turbine components, where creep rate and fatigue life data inform material processing optimizations.

High-Temperature Fracture Mechanics and Thermal Shock Testing

Our fracture mechanics testing services quantify a material's resistance to crack propagation at elevated temperatures, including measurements of fracture toughness (KIC, JIC), fatigue crack growth rates (da/dN), and crack tip opening displacement (CTOD). These tests are critical for assessing the damage tolerance of materials like carbon-carbon composites used in hypersonic heat shields. We also offer thermal shock testing, which subjects materials to rapid temperature changes (up to 500°C/min) via water quenching or air cooling, simulating the thermal transients experienced during spacecraft re-entry or engine startup. For example, we evaluate the thermal shock resistance of yttria-stabilized zirconia (YSZ) thermal barrier coatings, measuring critical temperature differences and residual strength retention after multiple thermal cycles. This service includes post-test microstructural analysis via scanning electron microscopy (SEM) to characterize crack morphology and failure mechanisms.
