【摘要】：在Gleeble-1500D熱模擬試驗(yàn)機(jī)上進(jìn)行單軸熱壓縮試驗(yàn),研究了形變溫度對(duì)GCr15SiMn鋼的組織尤其是網(wǎng)狀碳化物的影響。利用連續(xù)度系數(shù)來(lái)定量表征網(wǎng)狀碳化物的連續(xù)程度。綜合分析了形變溫度對(duì)晶粒尺寸以及網(wǎng)狀碳化物的連續(xù)度系數(shù)的影響。結(jié)果表明:隨形變溫度的升高,網(wǎng)狀碳化物的連續(xù)性與晶粒尺寸的變化規(guī)律保持較好的一致性。網(wǎng)狀碳化物的破碎程度隨形變溫度的降低而增大。綜合考慮網(wǎng)狀碳化物連續(xù)程度、晶粒尺寸以及變形抗力等因素,在軋后不控冷的條件下,GCr15SiMn的終軋溫度宜定在800~850℃,其中以850℃為最佳。
[Abstract]:Uniaxial thermal compression test was carried out on Gleeble-1500D thermal simulator. The effect of deformation temperature on the microstructure of GCr15SiMn steel, especially the reticular carbide, was studied. The continuity coefficient is used to quantitatively characterize the continuity of the reticulated carbides. The effect of deformation temperature on grain size and continuity coefficient of reticulated carbides was analyzed. The results show that the continuity of reticular carbides is consistent with the grain size with the increase of deformation temperature. The breaking degree of reticular carbides increases with the decrease of deformation temperature. Considering the continuous degree of mesh carbides, grain size and deformation resistance, the final rolling temperature of GCr15SiMn should be set at 800 鈩，
