The influence of drawing speed on fatigue strength TRIP steel wires
Tóm tắt
The paper assesses the effect of drawing speed on the fatigue strength and roughness of the surface of TRIP steel wires. The drawing process was accomplished on a testing machine and on a block drawing machine, while applying three drawing speeds: 0.02, 0.75 and 1.6 m/s. The performed tests showed a positive effect of drawing speed on the fatigue strength of wires. It was found that the better fatigue strength of wires drawn at the speed of 1.6 m/s compared to wires drawn at the speeds of 0.02 and 0.75 m/s was associated with a better surface condition of these wires.
