The Influence of HAZ on Fatigue Life of 16Mn Steel
In order to understand the influence of Heat-Affected Zone (HAZ) on fatigue properties of16Mn steel,a series of cyclic torsional tests were conducted on 16Mn weld metal,the base metal,andthe HAZ metal.The specimens of 2mm diameter were uniformly-spaced taken from a bulk 16Mnplate,which included a V-style welded joint in the center,and the space for each specimen was 4mm.From cyclic fatigue tests performed on specimens at different positions,one can observe that thefatigue damage evolution in the HAZ is faster than those in the weld and the base metal,I.e.,HAZ hasa significant effect on fatigue life of 16Mn.In addition,the peak stress decline curves of HAZspecimens in different rows are considerably diversified,but the damage evolution and fatigueproperties of HAZ metal are similar in spite of their locations.
