Use of copper material with high mechanical properties and thermal fatigue resistance.
The engineering technique measure, which is treating road bed to increase fatigue resistance, was put forward.
The effect of graphite morphology and alloying elements on thermal fatigue resistance of cast iron was studied.
High elasticity is the premise of low hardness for top roller, it can improve instantaneous dynamic circularity, extend the time of the elasticity fatigue resistance, improve yarn forming quality.
The material fracture toughness was adequate to ensure development of the full fatigue resistance of the weld detail.
