There are some measure condition intems which have influence on BH values of BH steel sheets during measure process, such as bake temperature, heating time and heating media, tensile speeds as well as different tensile machines.

BH值是超低碳BH钢板的一项特征值。

BH values increase significantly,and the higher baking temperature has little effect on BH values.

结果发现在烘烤温度小于140℃时,BH值随着烘烤温度的增加而显著增加,烘烤温度高于140℃时,温度对其影响不大;2%预应变、140℃烘烤条件下,超低碳钢的烘烤硬化效应在数分钟内迅速表现出来,20分钟内达到最大,随保温时间的继续增加,BH值并无明显变化;预变形量对BH值有一定的影响,大于2%的预变形反而会减弱烘烤硬化效应。

The results show that these carburized gears by using BH energizing reagentget finer microstructure,lower heat distortion,deeper carburizing layer,b.

实验结果表明使用BH催渗剂后的渗碳齿轮轮齿组织得到细化,热畸变减小,渗碳层深度增加,渗碳层碳化物分布形态得到改善,渗碳层硬度梯度趋于平缓。
