“…Particulate reinforced metal matrix composites (PRMMCs) are ideally suitable for many structural and functional applications due to their generally high specific strength, high stiffness, isotropic properties and relatively simple processing as compared with monolithic materials and conventional fiber-reinforced composites. − The properties of PRMMCs are determined not only by the reinforcement particulate size, distribution, volume fraction, and the matrix property, but also by the structure of the particulate/matrix interface. − As a ligament between particulates and matrix, the interface plays critical roles in the mechanical, physical and chemical properties of composite materials. A strong bonding interface is required for effective load transfer from the matrix to the reinforcement, leading to improved strength and stiffness. , The interfacial properties have also been found to determine the failure mode of the composites, where the failure initiated by interfacial debonding is likely to occur when the interface is weak. , As a result, investigations on the interface structure have been one of the most important topics of the processing of MMCs. − …”

High-strength lightweight Al-based composites are promising materials for a wide range of applications. To provide high performance, a strong bonding interface for effective load transfer from the matrix to the reinforcement is essential. In this work, the novel AlBC reinforced Al composites have been in situ fabricated through a liquid-solid reaction method and the bonding interface between AlBC and Al matrix has been unveiled. The HRTEM characterizations on the AlBC/Al interface verify it to be a semicoherent bonding structure with definite orientation relationships: (0001)//(11̅1);[112̅0]//[011]. Periodic arrays of geometrical misfit dislocations are also observed along the interface at each (0001) plane or every five (11̅1) planes. This kind of interface between the reinforcement and the matrix is strong enough for effective load transfer, which would lead to the evidently improved strength and stiffness of the introduced new AlBC/Al composites.

“…The interface of the composite influenced the composite characteristics as well. Because the interface contributed in the process of transferring load between matrix and reinforcement, the strong interface intensified force and vice versa [1].…”

Composites are one kind of new materials that continue constantly to develop. As a new composite material, we propose a solution overcoming the limitations of existing material, namely a composite structure consisting of two or more components with different material properties. In this composite, one component acts as reinforcement and the other as binder. They form a structure with combined properties are better than corresponding composite materials demonstrating several advantages such as light weight, strength, good rigidity and low production cost. T6 heat treatment process ensures the dissolving solution treatment in which the specimen heats at a temperature of 580°C and held for 6 h in state of rapidly cooled specimen with water down to room temperature. Furthermore, we study the process of aging at which the specimen heats again with various temperatures determined for first sampling of nine specimens as a temperature 160°C during 3, 5, and 7 h. Then second sampling of nine specimens heated under temperature 180°C during 3, 5, and 7 h, and third nine specimens was at temperature 180°C during 3, 5, and 7 h, and then slowly cooled to room temperature. From the analysis of the reaction product by EDX testing, the microstructure formed at the interface between matrix and reinforcement before T6 heating and then was treated by the T6 heat treatment at a temperature 200°C with holding time for 3, 5, and 7 h. The result remained the same, namely a new compound, that is, Al 2 MgSiO 4 formed, moreover formed additional element having different concentrations for various holding time.

Urn den wachsenden Anforderungen hinsichtlich Festigkeit, Temperatur-und Korrosionsbestandigkeit zu genugen, werden die modernen Werkstoffe zunehmend als "high tech" Produkte mit einer komplizierten Mikrostruktur konzipiert. Dies setzt eine effektive Kontrolle der Mikrostruktur mittels mikrostruktureller und rnikroanalytischer Verfahren voraus.In diesem Bericht wird eine Einfuhrung in die gegenwartig in der Werkstoff-Forschung eingesetzten mikrostrukturellen und mikroanalytischen Verfahren gegeben. Da die GroBe der maBgebenden Strukturelemente der Werkstoffe in einem weiten Bereich von einigen hundert Mikrometern bis zu atomaren Abmessungen variiert, ist die Ortsauflosung ein wesentliches Kriterium fur die Werkstoffuntersuchung.Die mikrostrukturellen und mikroanalytischen Verfahren werden vornehmlich unter dem Gesichtspunkt der Energieauflosung, der quantitativen Analyse und der Ortsauflosung diskutiert. Naher behandelt werden die analytische Transmissions-Elektronen-Mikroskopie (ATEM), die energiedispersive Elektronenstrahl-Mikroanalyse (EDX), die Auger-Elektronen-Spektroskopie (AES) und die Rontgen-Photoelektronen-Spektroskopie (XPS).Am Beispiel der Metallmatrix-Keramikfaser-Verbundwerkstoffe (MMC) wird gezeigt, daB die heute von den mikrostrukturellen und mikroanalytischen Verfahren gelieferten Informationen hinreichend die Mikrostruktur charakterisieren, fur eine erfolgreiche Werkstoffentwicklung aber auch notwendig sind.
