Overview
The Hengyi HY-3080WEF is a high-precision electromechanical universal testing machine engineered for mechanical property characterization of advanced ceramic materials under elevated temperature conditions. Designed specifically for porous ceramics and ceramic matrix composites (CMCs), this龙门-style (portal-frame) system integrates a robust load frame, high-stiffness crosshead guidance, and a thermally stable environmental chamber interface—enabling controlled uniaxial tensile, compressive, flexural, and shear testing from ambient up to 1200 °C (chamber-dependent). The system operates on closed-loop servo-controlled actuation, delivering force accuracy conforming to ISO 7500-1 Class 0.5 and ASTM E4 compliance for force verification. Its modular architecture supports seamless integration of high-temperature extensometers, furnace-compatible grips, and vacuum/inert-gas purge adapters—making it suitable for R&D labs and quality control environments where microstructural integrity and thermo-mechanical coupling must be rigorously evaluated.
Key Features
- High-rigidity portal frame with precision-ground ball-screw drive and preloaded linear guides for minimal deflection and axial alignment stability
- 30 kN load cell (optional multi-cell configuration) with ±500,000-count resolution, maintaining constant resolution across full measurement range without range switching
- Programmable test speed from 0.001 to 500 mm/min, with speed accuracy better than ±0.5% of set value per ISO 5893
- Real-time closed-loop control of force, displacement, and strain—supporting stress-rate (0.005–6% FS/s) and strain-rate (0.002–6% FS/s) protocols per ASTM D638 and ISO 527
- Dual-speed motorized crosshead movement (fast jog + fine positioning) with electronic end-stop protection and emergency overload cutoff (>110% FS)
- Integrated safety logic: automatic halt on time/strain/force limits, post-test auto-return, and continuous system diagnostics for overvoltage, overcurrent, and thermal anomaly detection
- Modular fixture interface compatible with Hengyi’s proprietary high-temp tensile jaws, compression platens, three/four-point bend fixtures, interlaminar shear fixtures, and fracture toughness holders (e.g., SENB, CT)
Sample Compatibility & Compliance
The HY-3080WEF accommodates a broad spectrum of brittle and quasi-ductile materials—including open- and closed-cell porous alumina, silicon carbide foams, zirconia-toughened ceramics, fiber-reinforced CMCs, and oxide/non-oxide composite laminates. Specimen geometries follow ASTM C1161 (flexure), C1211 (tensile), C1273 (interlaminar shear), and ISO 14125 standards. When paired with certified high-temperature extensometry and calibrated load cells traceable to NIM (China National Institute of Metrology), the system meets audit requirements for GLP-compliant laboratories. Data acquisition and control software logs all calibration events, operator actions, and parameter changes with timestamped metadata—supporting FDA 21 CFR Part 11 readiness when deployed with user access controls and electronic signature modules.
Software & Data Management
HENGYITEST™ v5.x software provides full test sequence definition, real-time visualization, and post-processing analytics. It acquires synchronized load, displacement, and strain signals at up to 1 kHz sampling rate and displays dynamic curves including stress–strain, load–displacement, load–time, and strain–time. Users may overlay multiple test records for comparative analysis, zoom into any segment with adjustable scaling, and annotate critical points (e.g., yield onset, peak load, fracture point). All curve features are exportable in CSV, XML, or PDF formats. The software supports automated calculation of tensile strength, Young’s modulus, Poisson’s ratio, elongation at break, compressive yield stress, flexural modulus, and shear strength—reporting results in accordance with ASTM D3039, ISO 527-2, and EN 843-2. Audit trails record user logins, method edits, test executions, and data exports for full traceability.
Applications
- Mechanical screening of porous ceramic scaffolds for biomedical implants (e.g., compressive yield strength, elastic recovery)
- Thermo-mechanical fatigue evaluation of SiC/SiC CMCs under cyclic loading at 800–1100 °C
- Interlaminar shear strength (ILSS) determination of ceramic-matrix laminates using short-beam or double-lap shear configurations
- Fracture toughness assessment (KIC) of sintered oxides via single-edge notched beam (SENB) tests per ASTM C1421
- Creep and stress-relaxation behavior quantification in refractory ceramics under sustained high-temperature loads
- Quality assurance testing of industrial ceramic filters, catalyst supports, and thermal barrier coatings (TBCs) substrates
FAQ
What temperature range is supported for high-temperature testing?
The HY-3080WEF is designed for integration with external high-temperature furnaces or environmental chambers; standard configurations support up to 1200 °C, contingent upon grip material selection (e.g., molybdenum, graphite, or ceramic-coated tool steel) and extensometer compatibility.
Can the system perform ASTM E21 creep tests?
Yes—the closed-loop strain and load control modes, combined with programmable dwell steps and long-term data logging, enable full compliance with ASTM E21 for metallic and ceramic creep testing, provided appropriate thermal stabilization and measurement hardware are installed.
Is third-party calibration documentation included?
Each unit ships with a factory calibration certificate traceable to national standards; optional UKAS- or CNAS-accredited calibration reports are available upon request.
How is data integrity ensured during extended tests?
The system employs non-volatile memory buffering, redundant power-fail recovery, and CRC-verified data streaming to prevent loss during multi-hour or multi-day experiments.
Are custom fixtures available for non-standard specimen geometries?
Hengyi offers OEM fixture design and machining services—including water-cooled grips, vacuum-compatible holders, and miniature test stages—for research-grade applications requiring specialized boundary conditions.
