Conclusions

  1. 1.

    Alloy VT9 with a lamellar structure, as compared with an equiaxed structure, is more capable of delaying fracture under single loads with low ductility and strength.

  2. 2.

    The superior fracture characteristics (double) of alloy VT9 with a lamellar structure are revealed by impact loading.

  3. 3.

    Titanium alloys with a lamellar microstructure are better able to delay crack development than alloys with an equiaxed structure, which is confirmed by operating tests of parts with a complex shape.
