Abstract
This work investigated the Vickers hardness and compressive properties of 0–30 % ZrMgMo3O12p/2024Al composites with controlled thermal expansion. The composites exhibited superior Vickers hardness and compressive properties, highly dependent on the ZrMgMo3O12 content. Under identical preparation conditions, an increase in ZrMgMo3O12 content allows for adjusting the Vickers hardness from 163 to 280 HV and the compressive yield strength from 330 to 702 MPa. Additionally, the 5 % and 10 % ZrMgMo3O12 composites exhibited 23 % and 8 % compressive strains, respectively. The Orowan strengthening effect of the ZrMgMo3O12 particles and the thermal mismatch stress at the particle-matrix interface were identified as the key strengthening mechanisms for the composites. However, excessive stress can lead to interfacial debonding and composite failure. Agglomeration of the ZrMgMo3O12 particles was observed beyond 10 % content. At 30 %, the thermal mismatch stress exceeded the binding strength, causing interfacial debonding and composite failure. The controlled mechanical properties of the 0–30 % ZrMgMo3O12p/2024Al composites indicate a promising potential for application in the aerospace and automotive industries and electronics and optical instruments sectors.
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.
