Properties of particle phases for metal-matrix-composite design

Abstract

Successful metallurgical design of metal-matrix-composites relies on the knowledge of the intrinsic property profiles of the metal matrix and especially the compounds employed for particles, whiskers or fibres. In this work we compiled the key properties melting point, bulk modulus, shear modulus, Young׳s modulus, density, hardness, Poisson׳s ratio and structure/space group from the widespread literature data for the most relevant compound types, i.e. borides, carbo-borides, carbides, oxides, nitrides and intermetallic phases.

Investigation of the response surfaces describing the mathematical model of the influence of temperature and BeO content in the composite materials on the yield and ultimate strength

“…Thus, in [8,9] the properties of materials are investigated, in particular, on the basis of X-ray diffraction, which makes it possible to reveal differences in the density of materials and to determine their properties depending on the loads of various types.…”

Fabrication of TiB2–Al1050 Composites with Improved Microstructural and Mechanical Properties by a Liquid Pressing Infiltration Process

“…Many studies on aluminum matrix composites (AMCs) have been conducted, because AMCs fabricated by adding ceramic reinforcements, such as silicon carbide (SiC) [1], alumina (Al 2 O 3 ) [2], boron carbide (B 4 C) [3], titanium carbide (TiC) [4], titanium diboride (TiB 2 ) [5], and hybrid [6] to an aluminum (Al) matrix, have excellent mechanical properties while maintaining low densities. Among the many ceramic reinforcements used in the fabrication of AMCs, TiB 2 is a very attractive reinforcement due to its superior Young's modulus [7], excellent hardness [8], and chemical stability with Al [9].…”

“…Compared to in-situ methods, ex-situ processes make it easier to control the volume ratio of reinforcements and are advantageous in terms of cost and productivity. However, ex-situ methods have a limitation in that, because the reinforcement is physically bonded to the base, the interface between the reinforcement and the base is unstable [7,10,11]. Therefore, many researchers have implemented additional processes to compensate for interface defects, the main disadvantage 2 of 11 of ex-situ methods.…”
