研究了V、Ti、V-Ti和V-Ti-Nb微合金化对高强度低合金钢疲劳性能的影响。试验结果表明,微量的钒使HSLA钢的疲劳性能得以改善;而钛和铌的加入对试验用钢的疲劳性能不利。
The effects of V, Ti, V-Ti and V-Ti-Nb microalloying on the fatigue properties of high strength and low alloy steels were studied. The test results show that trace amounts of vanadium can improve the fatigue properties of HSLA steels, while the addition of titanium and niobium is unfavorable to the fatigue properties of HSLA steels.
