Taking full advantage of intrinsic high strength of nano-reinforcements has been proven difficult in a composite until the concept of strain matching was experimental verified in a nanowire Nb/TiNi in-situ composite, which was obtained via solidifying eutectic Nb/TiNi and subsequent severe wire drawing. However, the volume fraction of the nano-reinforcement was dictated by eutectic reaction, which severely limited the development of high-performance composites. In this paper, the martensitic transformation nanocomposites were successfully acquired with increased volume fraction and changeable morphology of the nano-reinforcement through hot packaged ARB (PARB) and subsequent wire drawing. The nano-reinforcement with lamellar configuration in the composite could exhibit a large lattice strain of ~3.8%, which demonstrated the applicability and effectiveness of the strain matching principle in nano-lamellar composite. The obtained composites show a yield strength over 2.0 GPa and a quasi-linear elastic strain as larger as ~6.5% with adjustable apparent elastic modulus from 30 to 50 GPa.

事实证明，要充分利用复合材料固有的高强度，在复合材料中很难实现应变匹配的概念，直到在纳米线Nb / TiNi原位复合材料中对应变匹配的概念进行了实验验证，该复合材料是通过固化共晶Nb / TiNi并随后对其进行严格凝固而获得的。拉丝。然而，纳米增强体的体积分数是由共晶反应决定的，这严重限制了高性能复合材料的发展。在本文中，通过热包装的ARB（PARB）和随后的拉丝工艺，成功地获得了马氏体相变纳米复合材料，该复合材料具有增加的体积分数和可变的纳米增强形态。复合材料中具有层状构型的纳米增强材料可表现出约3.8％的大晶格应变，证明了应变匹配原理在纳米层状复合材料中的适用性和有效性。所得复合材料的屈服强度超过2.0 GPa，准线性弹性应变高达〜6.5％，表观弹性模量在30至50 GPa之间可调。
