Abstract

The strength and low-temperature stability of 09Mn2Si steel are investigated. The mechanical properties of samples obtained by 3D printing (electric arc surfacing) in CNC machine tools are close to those of samples obtained from rolled sheet. In fact, the strength and yield point after 3D printing are superior. However, the low-temperature stability of 09Mn2Si steel samples obtained by electric arc surfacing is worse than for samples from rolled sheet. The results show that electric arc surfacing is promising for the 3D printing of cold-resistant materials in CNC machine tools.

通过焊丝3D打印获得锰钢零件的低温稳定性

摘要

研究了09Mn2Si钢的强度和低温稳定性。在数控机床中通过3D打印（电弧堆焊）获得的样品的力学性能与从轧制薄板获得的样品的力学性能接近。事实上，3D打印后的强度和屈服点更胜一筹。然而，通过电弧堆焊获得的 09Mn2Si 钢样品的低温稳定性比轧制薄板样品差。结果表明，电弧堆焊在数控机床耐寒材料的3D打印方面具有广阔的应用前景。
