The Ti metal matrix composites containing silicon carbide (SCS 6) fibers, in five different lay-ups, have been tested at room temperature to determine static strengths and mechanical mental data and predicted values of the laminate properties and strengths showed good by: Miscellaneous: Characterization of fatigue damage in a metal matrix composite (SCS-6/Ti) at elevated temperature.

Ph.D. Thesis. Characterization of fatigue damage in a metal matrix composite (SCS-6/Ti) at elevated temperature. Ph.D. Thesis. Full Record. The response of a quasi-isotropic laminate of metal matrix composite, SCS-6/Ti in a thermomechanical fatigue (TMF) environment was investigated.

To achieve this, three sets of fatigue tests were conducted: 1) in-phase TMF (IP-TMF), 2) out-of-phase TMF (OP-TMF), and 3) isothermal fatigue (IF).Cited by: 6. This book has the stated aim of covering the physical and mechanical metallurgy, interfacial physics and mechanics, and processing of metal matrix composites (MMCs).

Several lay-ups of SCS-6/Ti metal matrix composites were tested in either a center hole or a double-edge-notched geometry.

At different cyclic stress levels, the number of cycles required to initiate a matrix fatigue crack at the notch was recorded. A strain-life fatigue curve was developed for the Ti matrix by: The normalized matrix crack density is determined by the number of matrix cracks and matrix crack growth rate.

Under the same applied stress level, SCS-6/Ti–15–3 showed the highest matrix crack density and the lowest residual stiffness, while SCS-6/Ti–22–23 exhibited the lowest matrix crack density and the highest residual stiffness. by: 5. The effect of fibre orientation and laminate stacking sequence on the tensile and fatigue behaviour of SCS-6/Ti composites were investigated.

The laminates used in this study were: (90)6, (0/ ± 45)s, (0/90)s, and (90/ +)s. The initiation and progression of microstructural damage at various stress levels was thoroughly characterized.
