Conclusions
-
1.
The axial residual stresses in the matrix of boron-aluminum increase with an increase in the yield point of the matrix, decrease with a decrease in adhesion at the fiber-matrix interface, and are independente of the volume content of fibers within the range 0.2–0.6.
-
2.
Thermal cycling of boron-aluminum to temperatures below the service temperature reduces tensile axial residual stresses and leads to the formation of compressive axial reresidual stresses. Thermal cycling to temperatures above the service temperature does not lead to any significant change in residual stresses.
-
3.
Tension of the specimen along the fibers causes a reduction in the axial residual stresses in the matrix of boron-aluminum, the stresses decreasing with an increase in the applied load.
