ABSTRACT: The traditional tetrahedron of materials science is less considered for the material's service behavior which made that a lot of materials are difficult to meet the application needs.  In fact, due to the interaction between material and service environment, the failure (corrosion, fatigue, wear, etc.) happens and may cause serious even catastrophic accidents which not only cause huge economic losses, but also affect people's health and survival and safety.  According to the materials degradation kinetics under the interaction of materials, environment and mechanics (service load), and in the concept of material genome, this report comprehensively introduces the high-throughput characterization techniques and efficient evaluation methods of materials' service behavior, including the statistical mapping of material properties in scanning electron microscopy, the uniform stress strain field on single sample with multi-cracks initiation method, the high-throughput test technology in high temperature pressurized water, the high-throughput computer simulation technology for material service behavior, the combination material chip service performance fast evaluation technology, the rapid evaluation of stress corrosion cracking (SCC) sensitivity in high temperature pressurized water by scratching repassivation, the corrosion protection coating evaluation technology by high-throughput environmental parameters, etc.  The new material genome method considered the materials performance was explained according to lab testing results.  As an example, the SCC evaluation term was shortened from years to a few days by the new technology.  Finally, the future needs were proposed including but not limited to the testing equipment and in-situ testing technology for environmental service performance under various scales, the multi-scale correlation technology, the data mining techniques and its utilization, the establishment of the new test evaluation standard, and artificial intelligence assisted above technologies and methods and so on.
