Effect of RE La element on the mechanical properties of 5CrNiMo forging die steel

College of Materials Science and Engineering, Inner Mongolia University of Technology, Hohhot 010051, China

摘要: 研究了加入稀土La后5CrNiMo鋼的強度、硬度、沖擊韌性變化;并在相同熱處理工藝條件下,與不添加稀土La的5CrNiMo鋼進行對比.結果表明:稀土La加入量在適當的范圍內可顯著提高鋼的強度、硬度和沖擊韌性;當稀土La質量分數為0.033%時,5CrNiMo鋼可獲得最好的綜合力學性能.

Abstract: The changes in strength, hardness and impact ductility of 5CrNiMo steel added different contents of RE La element were investigated. The 5CrNiMo steels with and without RE addition were compared after treated by the same heat treatment process. The result shows that the strength, hardness and impact ductility of 5CrNiMo steel are obviously improved when added a proper content of RE La element; the 5CrNiMo steel with RE La element of 0.033% in mass fraction has the best mechanical properties.
