利用最新研制的超高梯度定向凝固装置,研究了钴基高温合金的成分偏析及机械性能的变化,实验结果表明:其机械性能有较大提高,试样拉伸断口表现为高韧性穿晶断裂,裂纹起源于碳化物边缘.
The compositional segregation and mechanical properties of the cobalt-based superalloy were studied by using the newly developed ultra-high-gradient directional solidification equipment. The experimental results show that the mechanical properties of the cobalt-based superalloy are greatly improved, and the tensile fracture of the sample is characterized by high ductile transgranular fracture Cracks originate from the carbide edges.
