Preparing damage-tolerant titanium-matrix composites

JOM, 1994
In-situ TiB-reinforced titanium alloy composites have been produced by both rapid solidification and ingot metallurgy techniques. The reinforcements have been shown to result in strength and modulus improvements, improved fracture toughness, increased fatigue endurance limit, and better fatigue crack growth and creep resistance than conventional ...

Interfacial reactions in titanium matrix composites

Journal of Materials Science Letters, 1991
This letter presents some results of a study undertaken to determine the processing conditions necessary to produce acceptable composite microstructures using a variety of fibres and alloys, and to characterize the development of the interfacial reaction ...

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.

SiC filament/titanium matrix composites regarded as model composites

Journal of Materials Science, 1984
Two types of large diameter SiC CVD filaments have been investigated on both chemical and mechanical standpoints: a 100#m filament with a tungsten core (from SNPE) and three 140#m filaments with carbon cores and surface coatings (from AVCO). On the basis of microprobe (X-ray, Auger and Raman), X-ray diffraction and SEM analyses, it appears that the ...

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.

Critical Review Titanium Matrix Composites

1982
Titanium matrix composite systems are reviewed with emphasis on two systems; those containing silicon carbide coated boron filaments (B/SiC-Ti) and those containing beryllium metal either in powder or continuous filament form (Be/Ti).

Graded titanium boride fibre protective coatings for titanium matrix composites

Materials Science and Engineering: A, 1996
Graded titanium boride coatings (gTiB coatings) were deposited on SiC-SCS-6 fibres. Composites with an IMI834 matrix were processed by fibre coating with matrix and hot isostatic pressing (HIPing) of matrix coated fibres. The thermal stability of the composites was investigated by the determination of the tensile and interface properties after a ...

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 Maps for Titanium Matrix Composites

1996
The present article attempts to bring together many of the observations and measurements pertaining to fatigue cracking and fracture of unidirectional titanium matrix composites at ambient temperature into a fatigue fracture map. The map identifies the regimes in which various mechanisms operate, allowing fatigue life predictions to be made. The map is

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 ...
