For the past 30 years, nanoindentation has provided critical insights into the microstructure-strength relationship for a wide range of materials. However, it has traditionally been limited to quasistatic testing at room temperature, which has hindered a holistic understanding of microstructurally induced deformation mechanisms and their dynamic evolution as a function of the temperature and strain rate. Over the past decade, the operational scope of nanoindentation has expanded dramatically. Temperatures up to 1100°C and strain rates as high as 10 s and as low as 10 s have become accessible. In addition, advanced techniques allow tracking microstructural evolution and corresponding changes in mechanical behavior during deformation under extreme conditions. These advancements have transformed nanoindentation into a versatile tool for comprehensive materials characterization, enabling high-throughput investigations under multimodal conditions.
在过去30年里，纳米压痕技术为深入了解各种材料的微观结构与强度关系提供了关键见解。然而，传统上它仅限于室温下的准静态测试，这阻碍了对微观结构诱导的变形机制及其随温度和应变速率的动态演变的全面理解。在过去十年中，纳米压痕技术的操作范围大幅扩展。高达1100°C的温度以及高达10 s和低至10 s的应变速率都已能够实现。此外，先进技术允许在极端条件下跟踪变形过程中的微观结构演变以及力学行为的相应变化。这些进展已将纳米压痕技术转变为一种用于全面材料表征的多功能工具，能够在多模态条件下进行高通量研究。
