Fatigue crack growth in a fibre-reinforced titanium MMC at ambient and elevated temperatures

Fatigue crack growth rates in an SCS6 fibre-reinforced Ti-15-3 based metal-matrix composite have been measured at a number of different temperatures, frequencies and load ratios. In specimens fatigued under a constant load range, crack growth rates decrease with increasing crack length, despite an i...

Description
Summary:Fatigue crack growth rates in an SCS6 fibre-reinforced Ti-15-3 based metal-matrix composite have been measured at a number of different temperatures, frequencies and load ratios. In specimens fatigued under a constant load range, crack growth rates decrease with increasing crack length, despite an increase in the nominal applied stress intensity range ( δK). At room temperature the crack arrests after growing for
