Abstract

The interface of ceramic particles and metal matrixes extremely impacts the mechanical properties of particle-reinforced metal matrix composites,especially at elevated temperatures.We provide a strat-egy for constructing extremely fine,in situ-formed coherent nanolamellar solute-twining architectures in a supersaturated MAX/Ni composite to modify the interface,aiming for higher strengths.Through this unique architecture,a coherent interface of ceramic particles and a metal matrix is formed,with an enormous coherent interface known as a ladder interface.The tensile strength at 1023 K is approxi-mately 1 GPa by forming a thermally stable Schwarz crystal structure(＜3 nm).Developing heat-tolerant composites using this architecture may enhance the materials'available properties for high-temperature applications.
