Abstract

This paper describes the fabrication and properties of novel laminated metal-ceramic composites obtained from highly filled preceramic papers based on Ti₃Al(Si)C₂ (TAC) MAX-phase and Ta metal foils. Composites with different architectures were formed by stacking of preceramic papers and metal foils, followed by spark plasma sintering at 1150 °C and 50 MPa for 5 min. The obtained laminated materials were characterized by homogeneous microstructure of individual layers, high strength and quasi-ductile fracture behavior. A reaction layer of ∼7 μm in thickness consisting mainly of silicides and intermetallics is revealed. Thermal conductivity and diffusivity of laminated composites improved with increasing Ta/TAC ratio. Depending on the architecture, the bending strength of composites ranged from 480 to 650 MPa. Fracture toughness of the composites increased from 8.1 to 11.4 MPa × m^1/2 as the thickness ratio of Ta/TAC layers increased from 1/3 to 1/1. The toughening of the fabricated laminates is explained by the complex macroscale and microscale mechanisms discussed in the paper. The obtained results demonstrate that the superior mechanical properties and favorable thermal performance of the fabricated metal-ceramic composites make them promising candidates for advanced structural applications.

由Ta箔和Ti3Al(Si)C2填充预陶瓷纸制备的准延性金属-陶瓷层合复合材料的力学和热性能

本文介绍了基于Ti3Al(Si)C2 (TAC) max相和Ta金属箔的高填充预陶瓷纸层压金属陶瓷复合材料的制备和性能。将预陶瓷纸与金属箔叠加，在1150℃、50 MPa条件下烧结5 min，形成不同结构的复合材料。所制备的层合材料具有层间组织均匀、强度高和准韧性断裂等特点。反应层厚度为~ 7 μm，主要由硅化物和金属间化合物组成。随着Ta/TAC比的增大，复合材料的导热系数和扩散系数均有所提高。根据结构的不同，复合材料的抗弯强度从480到650兆帕不等。当Ta/TAC层厚度比从1/3增加到1/1时，复合材料的断裂韧性从8.1 MPa × m1/2增加到11.4 MPa × m1/2。本文讨论了复合材料的宏观和微观增韧机理。结果表明，制备的金属陶瓷复合材料具有优异的力学性能和良好的热性能，具有较好的应用前景。

期刊介绍： Ceramics International covers the science of advanced ceramic materials. The journal encourages contributions that demonstrate how an understanding of the basic chemical and physical phenomena may direct materials design and stimulate ideas for new or improved processing techniques, in order to obtain materials with desired structural features and properties. Ceramics International covers oxide and non-oxide ceramics, functional glasses, glass ceramics, amorphous inorganic non-metallic materials (and their combinations with metal and organic materials), in the form of particulates, dense or porous bodies, thin/thick films and laminated, graded and composite structures. Process related topics such as ceramic-ceramic joints or joining ceramics with dissimilar materials, as well as surface finishing and conditioning are also covered. Besides traditional processing techniques, manufacturing routes of interest include innovative procedures benefiting from externally applied stresses, electromagnetic fields and energetic beams, as well as top-down and self-assembly nanotechnology approaches. In addition, the journal welcomes submissions on bio-inspired and bio-enabled materials designs, experimentally validated multi scale modelling and simulation for materials design, and the use of the most advanced chemical and physical characterization techniques of structure, properties and behaviour. Technologically relevant low-dimensional systems are a particular focus of Ceramics International. These include 0, 1 and 2-D nanomaterials (also covering CNTs, graphene and related materials, and diamond-like carbons), their nanocomposites, as well as nano-hybrids and hierarchical multifunctional nanostructures that might integrate molecular, biological and electronic components.
