Effect of ultrasonics on the properties of hardened high-speed steel R6M5
The action of ultrasonic treatment for hardneed high-speed steel R6M5 with optimum treatment schedules (σp = 164 MPa, τ=10 min) leads to a reduction in first order residual stresses by ∼20%.
Subsequent single and two-stage tempering of steel R6M5 at 555±5°C makes it possible to increase hardness by HRC 1.5–2.0 and the ultimate bending strength by 400–600 MPa.
