热变形工艺对低硫易切削钢中硫化锰形态演变的影响
|
摘要
利用Gleeble-3500热模拟试验机、扫描电镜研究了热变形工艺对低硫易切削钢中硫化物形态的影响。用图像处理软件对不同工艺下硫化物的形貌、长宽比进行了观察和统计。结果显示:当变形温度较低时,硫化物的相对塑性随着形变量的增加而提高;高温大形变量有利于降低硫化物相对塑性,获得长宽比较小的硫化物。当变形温度大于1000℃时,钢中硫化物呈短棒状或椭圆形。
The influence of the hot deformation processes on MnS inclusion morphology was studied based on Gleeble-3500 and scanning electronic microscope( SEM). The length-width ratio statistics was conducted by image processing software. The results indicate that the relative plasticity increases at low temperature. Whereas,it will decease at a higher temperature at which low length-width ratio MnS inclusion could be obtained. When the deformation temperature is above 1000 ℃,MnS inclusions show the short rod-like or elliptic morphology.
