Influence of the Grain Size on the Dispersion Strengthening of VT1-0 Alloy Implanted with Aluminum Ions

Abstract:

The method of translucent diffraction electronic microscopy conducted researches of a microstructure and phase structure of a titanic alloy of VT1-0 implanted by ions of aluminum. There are two types of grains; 1) large grains (LG) with an average size of 1.4 microns and 2) the small grains (FG) with an average size of 0.5 μm. It is established that as a result of radiation the ion-alloyed layer, on the basis of α-Ti grains is formed. The sizes, form and places of localization of secondary phases (Ti₃Al, Al₃Ti and TiO₂) depend on the size of grain of a titanic matrix. The size of dispersive hardening of σ_orfor different type of grains on depth of the ion-alloyed layer is calculated. It is shown that in MZ the size σ_or is provided only with TiO₂ particles, in LG – generally TiO₂ particles.
