On the Formation of Internal Fatigue Damage in Association with Twins in α-Titanium
AbstractCoarse-grained (∼0·3 mm) α-titanium has been fatigued in tension/compression about a zero mean load at a frequency of ∼ 100 Hz at room temperature. A combined metallographic and microbeam X-ray analysis revealed the presence of { 10 1 ¯ 2 } -, { 11 2 ¯ 1 } -, and { 11 2 ¯ 2 } - type twins. In internal grains, i.e. grains completely constrained by surrounding material, fatigue _damage was observed to be associated with the { 11 2 ¯
