Reliability of materials

Extreme Environment

As the future mobility industry expands, core structural materials are increasingly exposed to harsher operational envelopes such as space, deep sea, and polar regions. Since unexpected material failure in these environments can lead to catastrophic consequences, it is essential to accurately characterize the unique behavior of materials under extreme conditions.

Our research involves in-depth analysis of tensile and fracture properties by simulating cryogenic temperatures—utilizing liquid hydrogen and nitrogen—as well as elevated temperatures encountered in engines and aerospace structures. Furthermore, we conduct precision evaluations including SSRT (Slow Strain Rate Technique) to address critical threats such as corrosion and hydrogen embrittlement. By identifying specific vulnerability factors for each extreme environment, we provide next-generation material solutions that ensure structural integrity under the most demanding conditions.

Environmental Simulation: Establishing material testing environments that simulate aerospace and space conditions using high-temperature and cryogenic chambers.
Mechanical Property Characterization: Performing quantitative evaluations of changes in mechanical properties, such as tensile strength, ductility, and fracture toughness, across a wide range of temperatures.
Degradation Analysis: Investigating material degradation mechanisms caused by corrosion and hydrogen embrittlement while determining critical stress thresholds through the Slow Strain Rate Technique (SSRT).
Performance Optimization: Providing high-reliability material selection and design guidelines optimized for specific operational environments based on comprehensive extreme environment databases.
