Kotko A. The principless of strain hardering of the Titanium and alloys based on it.

The work is dedicated to study of deformation laws of hardering of Ti and some Ti based alloys.It is shown that the parameter of deformation hardering is equal n=0,91 in the investigated interval of temperature and degree of deformation for technically pure Ti. The ifluence of phase structure of an alloy and morphology of phase components on numerical value of n is illustrated.The parameter of deformation hardering changes from 0,51 in lammelar structures to 0,81 in globular structures.It is determined that for Ti alloys with BCC lattice the parameter n can change in an interval 0,5-1,0.It is caused by allocation of dispersed precipications of the omega phase.The results of study of the influence of the alloying elements on phase structure and morphology of "titanic steel" and "titanic cast iron" after hardering are discribed.
