Mechanical properties and thermal stability of nanocrystalline trinary alloys

纳米晶体金属（即，具有纳米级晶粒的金属）通常限于二元合金，例如Ni-Co和Ni-Fe合金。它们的主要缺点是这种合金的热稳定性差，妨碍了它们在高温下的使用。拟议的项目旨在开发 ** 和测试下一代纳米晶合金（例如，Ni-Co-Fe、Ni-Fe-Cu、Ni-Co-Cu、Ni-Co-W），具有高强度 ** 和热稳定性。该项目将为新型纳米晶合金的设计提供有价值的数据集，这些合金有望 ** 显著提高强度密度比，并在约400-600 °C的工作温度下保持稳定。传统的纳米晶涂层不能在高于400 °C的温度下使用。这种新型合金可以 ** 用作保护涂层，这将对航空航天、汽车和相关制造 ** 行业有用。该项目将使Integran Technologies在全球 ** 制造行业，特别是在金属电镀市场中处于更有竞争力的地位。

Nanocrystalline metals (i.e., metals with nanometer-scale grains) made by electroplating or electroforming are**generally limited to binary alloys, for example Ni-Co and Ni-Fe alloys. Their main drawback is that the poor**thermal stability of such alloys impedes their use at elevated temperatures. The proposed project aims to develop**and test next-generation nanocrystalline alloys (e.g., Ni-Co-Fe, Ni-Fe-Cu, Ni-Co-Cu, Ni-Co-W) with high strength**and thermal stability for Integran Technologies.**This project will provide valuable dataset for the design of new nanocrystalline alloys, which are expected to**significantly increase strength-to-density ratios and be stable at a working temperature of ~400-600 °C.**Conventional nanocrystalline coatings cannot be used at a temperature higher than 400 °C.Such new alloys can**be used as protection coatings, which will be useful for aerospace, automobile, and relevant manufacturing**industries. The benefit of this project will lead Integran Technologies a more competitive position in global**manufacturing sectors, particularly in the metal electroplating market.
