Developments in Titanium Metal Matrix Composites

JOM, 1984
A review is given of developments in the titanium metal matrix composites (MMC) area over the past two decades. Particular topics of discussion include: fibers, matrices, fabrication techniques, mechanical properties of both the fiber and composite, and fractography. It is demonstrated that the increased metallurgical understanding of the composite has

Optimizing the consolidation of titanium matrix composites

Acta Materialia, 1997
Abstract The high temperature consolidation of fiber reinforced metal matrix composite preforms seeks to eliminate matrix porosity (i.e. to increase the relative density) while simultaneously minimizing fiber microbending/fracture and the growth of reaction products at the fiber-matrix interface.

3M TITANIUM MATRIX COMPOSITES

Alloy Digest, 1997
Abstract 3M TITANIUM MATRIX COMPOSITES are produced by electron-beam evaporation to apply Ti-6Al-4V coating to high-strength, high-modulus silicon carbon fibers. The resulting composite has increased strength and stiffness over monolithic titanium/titanium alloy parts.

Investment Casting of Titanium Matrix Composites

Materials Science Forum, 2005
The aim of the present work is to investigate the possibility of in-situ synthesis and net-shape of the titanium matrix composites (TMCs) using a casting route. From the scanning electron microscopy (SEM), electron probe micro-analyzer (EPMA), X-ray diffraction (XRD) and thermodynamic calculations, the spherical TiC and needle like TiB reinforced ...

Casting and Modeling of Titanium Matrix Composites

Key Engineering Materials, 2007
The aim of this study is to establish the net-shape forming of titanium matrix composites (TMCs) shot sleeve for Al alloys die-casting using a casting route. In-situ synthesis and casting of TMCs were carried out in a vacuum induction melting furnace. The synthesized (TiC+TiB) TMCs were examined using an scanning electron microscopy and electron probe ...

Titanium metal matrix composites: An overview

Composites Part A: Applied Science and Manufacturing, 2019
Abstract Titanium matrix composites (TMCs) offer high specific strength and stiffness compared with steel and nickel-base materials. High-temperature TMCs can offer up to 50% weight reduction relative to monolithic superalloys while maintaining equivalent strength and stiffness in jet engine propulsion systems.

Interfacial reactions in titanium-matrix composites

JOM, 1989
A study of the interfacial reaction characteristics of SiC fiber-reinforced titanium aluminide and disordered titanium alloy composites has determined that the matrix alloy compositions affect the microstructure and the distribution of the reaction products, as well as the growth kinetics of the reaction zones.

Titanium diboride copper-matrix composites

Journal of Materials Science, 1997
Copper-matrix titanium diboride platelet (3–5 μm) composites containing 15–60 vol% TiB2, were fabricated by powder metallurgy, using copper-coated TiB2 (60 vol% TiB2) and various amounts of copper powder. The porosity was ≤0.5% when TiB2 was ≤48 vol%. Above 48 vol% TiB2, the porosity increased abruptly with increasing TiB2 content, reaching 6.7% at 60 ...

Crippling of Titanium Matrix Composite Stiffeners

Journal of Composite Materials, 1992
Using established principles of laminate buckling theory and post buckling load redistribution, a theory is derived for crippling analysis of specially ortho tropic or very nearly specially orthotropic laminated composite stiffeners. Results from testing of SCS-6/Ti-15-3 titanium matrix composite (TMC) stiffener segments are also presented and show ...
