Overview
The Yuelian YL-1161 High-Temperature Tensile Testing Machine is an electromechanical universal testing system engineered for precise mechanical property evaluation of metallic alloys, high-performance polymers, ceramics, and composite materials under elevated thermal conditions. It operates on the principle of controlled uniaxial force application in accordance with standardized tensile test methodology—applying calibrated load through a servo-controlled actuator while simultaneously measuring displacement, load, and strain. The system integrates a thermally insulated furnace chamber or environmental chamber (optional), enabling stable temperature control from ambient to 300 °C during active loading. This capability supports ASTM E21, ISO 6892-2, and CNS 2276 protocols for high-temperature tensile testing, delivering reproducible stress–strain curves, yield strength (Rp0.2), ultimate tensile strength (UTS), elongation at break, and modulus of elasticity under defined thermal boundary conditions.
Key Features
- Modular high-temperature test chamber with PID-controlled heating and dual-zone thermal insulation, minimizing axial heat gradient across the gauge length
- High-rigidity load frame with crosshead travel up to 1,200 mm and precision-ground ball-screw drive mechanism for minimal backlash and thermal drift
- Interchangeable load cells (5 kN, 10 kN, 25 kN, 50 kN) featuring ±0.5% full-scale accuracy per ISO 7500-1 Class 1
- Dual-mode control architecture: standalone touchscreen interface with real-time graphing, plus PC-based control via Windows-compatible software with scripting support (VB.NET / Python API)
- Integrated safety interlocks including over-temperature cutoff, emergency stop circuitry compliant with IEC 60204-1, and automatic load cell zeroing before thermal soak
- Compliance-ready data logging with timestamped metadata, audit trail, and user-access-level permissions aligned with GLP and FDA 21 CFR Part 11 requirements
Sample Compatibility & Compliance
The YL-1161 accommodates standard tensile specimens per ASTM E8/E21 (flat and round bar), ISO 6892-1/6892-2, and CNS 2276 geometries—including dog-bone, rectangular, and threaded-end configurations. Specimen gripping is achieved via pneumatic or manual wedge-action grips with replaceable jaw faces optimized for high-temperature service (Inconel-lined or ceramic-coated). Optional accessories include high-temperature extensometers (capable of 1,200 °C surface measurement), vacuum-compatible chambers, and inert-gas purge kits for oxidation-sensitive materials. All test reports generated include traceable calibration certificates for load cell, displacement transducer, and furnace thermocouples (Type K or S), satisfying ISO/IEC 17025 documentation requirements for accredited laboratories.
Software & Data Management
The proprietary YL-TestSuite software provides full test sequence programming, real-time parameter monitoring (load, displacement, temperature, strain), and post-test analysis tools including automatic yield point detection (0.2% offset method), tangent modulus calculation, and creep compliance fitting. Raw data exports are available in CSV, XML, and MDF4 formats for third-party analysis (MATLAB, Origin, QDA). The software maintains an immutable audit trail recording operator ID, test parameters, calibration events, and any manual overrides—enabling full traceability during regulatory inspections. Network deployment supports centralized license management and role-based access control (RBAC) for multi-user environments operating under GMP or ISO 9001 quality systems.
Applications
- Evaluation of creep resistance and time-dependent deformation in nickel-based superalloys used in turbine blades
- Thermal-mechanical characterization of aerospace-grade carbon-fiber-reinforced polymer (CFRP) laminates
- Quality assurance testing of brazed or sintered metal joints subjected to service temperatures above 200 °C
- Development and validation of high-temperature adhesives and sealants per MIL-STD-883 or IPC-TM-650
- Research into phase-transition-induced embrittlement in shape-memory alloys (e.g., NiTi) across austenite–martensite transformation ranges
FAQ
What temperature uniformity can be expected across the specimen gauge length during testing?
Typical axial temperature deviation is ≤±2 °C over a 25 mm gauge length when operated at 300 °C using the standard furnace configuration.
Is the system compatible with third-party extensometers?
Yes—the YL-1161 provides analog voltage input (±10 V) and digital TTL synchronization ports supporting industry-standard high-temperature extensometers from ZwickRoell, Instron, and MTS.
Does the software support automated test reporting in PDF format with company branding?
Yes—customizable report templates allow insertion of corporate logos, headers, footers, and signature fields, with output compliant with ISO 14289-1 (PDF/A-2u) for long-term archival.
Can the machine perform compression or flexural tests at elevated temperatures?
Yes—using appropriate fixtures (e.g., platens for compression, three-point bend assemblies), the system executes ASTM E9, E292, and ISO 14125 protocols under identical thermal control conditions.
What calibration documentation is provided with shipment?
Each unit ships with NIST-traceable calibration certificates for load cell, displacement encoder, and furnace thermocouple, valid for 12 months from date of manufacture.
