Effect of deformation parameters on plasticity and resistance to deformation of alloy KhN77TYuR
- 19 Downloads
A substantial increase of the resistance to deformation in the temperature range investigated is observed at strain rates up to 35 sec−1. Higher strain rates have a negligible effect on the resistance to deformation.
High plasticity (ψ≥80%) is observed at 1050–1100° at all strain rates investigated, and at strain rates up to 35 sec−1 at 1150°.
Hot plastic deformation of alloy KhN77TYuR should be conducted in the temperature range of 1150–1050°.
