无间隙冷轧汽车钢的内耗谱
INTERNAL FRICTION SPECTRUM OF THE INTERSTITIAL FREE COLD-ROLLED STEEL FOR AUTOMOBILE
【摘要】 对无间隙冷轧汽车钢进行了内耗谱测试,结果表明经过960℃保温的试样,在原位退火未施加变形的条件下,出现Snoek-Ke-Koster(即SKK)峰;此外,供货态板材在700和720℃两种不同温度原位退火后,钢的高温内耗发生改变且在磁场中的行为明显不同
【Abstract】 The spectrum of internal friction in a interstital free cold-rolled steel produced by Baoshan Iron and Steel Companay (BIF) for automobile has been studied. The results showed that a Snoek-Ke-Koster peak appears for in situ annealing steel at 900℃ and there are different influences of magnetic field on the internal friction in the specimens annealed at 700℃ and 720℃.
