Tests of quenched Ti--Mo alloys show two valleys in the yield strength curves. One of them is associated with martensitic ..cap alpha..'' phase and the other with mechanically unstable ..beta.. phase. The two valleys are separated by a peak associated with the formation of ..omega.. phase in ..beta.. phase of the critical composition during quenching. No ..omega.. phase is formed in quenched alloys VT6 and VT16. The valley of the yield strength associated with the ..cap alpha..'' phase runs together with the valley associated with unstable ..beta.. phase. The low yield strength of quenched alloys consisting of ..cap alpha..'' phase is due to a low shear modulus, while in alloys with mechanically unstable ..beta.. phase it is due to the macroscopically oriented transformation of ..beta.. phase to martensite under the influence of applied stress. The valley in the yield strength of quenched alloy VT16 does not lead to any improvement in workability in upsetting of cylindrical samples or coldheading of bolts.
