The internal stress and defects decrease with the increase of heat treatment temperature and this makes magnetic domains wider and more orderly but the carbides containing Ti precipitate along the grain boundaries which cause local components and structure heterogeneousness in these areas .

热处理温度越高，组织内应力和缺陷的减少使得磁畴的排列越来越整齐，磁畴宽度也越大，但晶界附近少量含Ti碳化物析出，导致局部成分和结构的非均匀化，不仅使得该区域磁畴细化，而且阻碍了畴界的移动，从而影响了阻尼性能的提高。

The transition metal carbides were a new class of catalysts which had good catalytic activity and selectivity and were widely used in hydrogenolysis,dehydrogenation,desulfidation,denitrification,reforming,and other hydrocarbon conversion reactions.

过渡金属碳化物作为一种催化新材料得到了人们广泛的关注，在催化加氢、脱氢、脱硫、脱氮和重整等方面，表现出优良的催化活性和选择性。

In order to restrain IGC,the solid solution temperature should be higher than 1 100 ℃ and then the tubes should be cooled quickly enough to avoid a lot of precipitation of Cr23C6 carbide at about 840 ℃,which lead to be sensitive to IGC of the steel.W...

试验结果表明，随固溶温度升高，晶间腐蚀敏感性下降，为抑制晶间腐蚀，固溶温度应≥1100℃；钢管固溶后应快速冷却，以避免840℃附近Cr23C6碳化物大量析出导致敏化；固溶温度超过1100℃，随固溶温度升高，晶粒度等级和室温强度逐渐下降。

The improvement of the frictional resistance is mainly due to the effect of carbon on residual austenite and the morphology of carbides, and an appropriate amount of residual austenite is helpful to improve the impact toughness and hardness of matrix; The spherical VC can hinder the initiation and propagation of crack and improve the frictional resistance.

碳含量对耐磨性的影响主要是通过对基体残余奥氏体量和碳化物形态表现出来的，适量的残余奥氏体使基体具有较好的冲击韧度及硬度；形态较为固整的VC颗粒，对裂纹的萌生及扩展起阻碍作用，从而使材料的耐磨性提高。

The suppression of carbide formation is associated with the nucleating properties of the nodularizer and inoculant alloys.
