摘要
研究了ＢＰＨ３４０冷轧汽车钢板的内耗谱，得到了原始态、变形态及在不同温度下退火、淬火试样的Ｑ－１ｔ曲线，以及各种因素对内耗谱的影响，说明生产汽车钢的内耗谱具有其特殊性和复杂性．
In present paper,the internal friction spectrum in BPH340 coldrolled steel for automobile has been studied. The curves of Q-1t in the specimens on the condition of commercial production,furnace cooling (F.C) after holding them at different temperatures and water cooling (W.C) as well as deforming at room temperature are measured. It is shown that the internal friction spectrum of steel produced is of specificity and complexity.
