The deformation characteristics of quenched and aged Ti--V alloys in the composition range 20 to 40 wt percent vanadium have been examined by optical metallography and transmission electron microscopy. A coarse lenticular deformation product similar in appearance to previously reported strain induced ''martensites'' was found to be associated with the occurrence of the omega phase. These features proved to be (112)(111) twins. In the omega bearing alloys prolonged aging resulted in a transition of the deformation mode from twinning to slip at a point which corresponded either to the onset of embrittlement or ..cap alpha.. phase precipitation.
