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 ...

Titanium matrix composite lattice structures

Composites Part A: Applied Science and Manufacturing, 2008
Abstract Cellular materials made from high temperature composites with efficient load supporting lattice topologies and small cell sizes would create new options for light weight, high temperature structures. A method has been developed for fabricating millimeter cell size cellular lattice structures with a square truss topology from 240 μm diameter ...

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 ...

In-situ-reinforced titanium matrix composites

Materials Science and Engineering: A, 1991
Abstract An approach has been developed to fabricate discontinuously reinforced composites with an extremely fine reinforcement size. Specifically, composites are formed in situ by plasma melting an agglomerate consisting of two dissimilar powders that react to form a reinforcement within a metal matrix.

Rapid Infrared Joining of Titanium Alloys and Titanium Matrix Composites

MRS Proceedings, 1993
AbstractA rapid infrared joining (RIJ) technique has been developed at the University of Cincinnati for high temperature materials. This technique takes only a few seconds to a few minutes to join parts up to 1.8 cm in thickness. The advantages of the RIJ technique are quick, simple, inexpensive, no vacuum or pressure needed, no effect on the ...

Fatigue Response of Joint Between Titanium and Titanium Matrix Composite

47th AIAA/ASME/ASCE/AHS/ASC Structures, Structural Dynamics, and Materials Conference<BR> 14th AIAA/ASME/AHS Adaptive Structures Conference<BR> 7th, 2006
An integrally fabricated double scarf joint between a monolithic titanium alloy and the silicon carbide fiber reinforced titanium matrix composite was characterized under the fatigue loading condition. The mechanical response of the functionally graded material system was in-between those of the alloy and the composite under all loading conditions ...

Composite-processed Nb3Sn with titanium addition to the matrix

Journal of Applied Physics, 1982
The effects of a titanium addition to the matrix on the superconducting properties and the metallurgical aspects of the composite-processed Nb3Sn have been studied. The titanium added to the matrix is found to diffuse readily into the Nb3Sn layer. The small amount of the titanium addition to the matrix significantly increases the growth rate and the ...
