Abstract

The tensile performance of a boron-containing Ni_43.9Co_22.4Fe_8.8Al_10.7Ti_11.7B_2.5 multi-principal element alloy was studied through tensile tests after electrochemical hydrogen pre-charging. Hydrogen pre-charging notably reduced both the elongation and strength of the alloys. Brittle cracking regions and an increased number of cracks appeared at the hydrogen pre-charged alloys after tensile deformation. Tensile cracks in the hydrogen pre-charged samples propagated in the mixed intergranular and transgranular cracking modes. Grain boundaries containing the hexagonal close-packed phases were susceptible to crack propagation. The cracking behavior of the hydrogen pre-charged alloys was attributed to the combined hydrogen-enhanced localized plasticity and hydrogen-enhanced decohesion mechanisms.

预充氢对含硼多主元素合金拉伸性能的影响

通过电化学预充氢后的拉伸试验，研究了含硼Ni43.9Co22.4Fe8.8Al10.7Ti11.7B2.5多主元素合金的拉伸性能。预充氢显著降低了合金的伸长率和强度。拉伸变形后，预充氢合金出现脆裂区，裂纹数量增加。预充氢试样的拉伸裂纹以沿晶和穿晶混合裂纹模式扩展。含六方密排相的晶界易受裂纹扩展的影响。预充氢合金的开裂行为是由氢增强的局部塑性和氢增强的脱粘机制共同作用的结果。
