This project aims to develop metallic composites of superior mechanical properties based on the principle of elastic strain coupling between ultrahigh-strength nanowires and phase transforming matrix. This new composite design concept has not been explored in the literature. Using the principle of elastic strain coupling, the composite is able to exhibit extraordinary mechanical properties unmatched by any existing engineering materials, including high strength, low Young’s modulus and high elastic strain limit. This new concept is a breakthrough and offers a unique opportunity to overcome a long-standing challenge in nanowire composite design, commonly known as the “valley of death”.

本计画的目的是利用超高强度奈米线与相转换基体间的弹性应变耦合原理，开发具有上级机械性质的金属复合材料。这种新的复合材料设计概念尚未在文献中探讨。利用弹性应变耦合原理，复合材料能够表现出任何现有工程材料无法比拟的非凡机械性能，包括高强度，低杨氏模量和高弹性应变极限。这一新概念是一个突破，并提供了一个独特的机会，以克服纳米线复合材料设计中的长期挑战，通常被称为“死亡谷”。
