Effect of surface roughness of the endurance of titanium alloy VT6 and the effectiveness of strain hardening it by surface plastic deformation
- 29 Downloads
Titanium alloy VT6 is considerably less sensitive than, say, high-strength steel, to the magnitude of surface roughness in pulsating bending and tension in the low-cycle region.
Strain-hardening alloy VT6 by surface plastic deformation is very effective: depending on the initial roughness of the surface and the loading conditions, shot-blasting and vibroimpact can increase endurance by 30 times.
For specific loading conditions, in the use of certain methods of strain-hardening by surface plastic deformation there is a value of initial surface roughness for alloy VT6 which is optimal from the. point of view of providing high endurance.
