After adding various amounts of Re elements into titanium zirconium molybdenum alloy found the flexural strength of TZM alloy has no significant increase. What’s more, compared with pure TZM alloy which didn’t add Re element the flexural strength decreased. But with the added amount of Re elements increase, TZM alloy flexural strength graph has a clear linear region, indicating that the alloy occurs not completely plastic deformation before breaking. However, itself has room temperature brittleness while exhibits a certain degree of temperature toughness.
Analysis alloy’s bending fracture surface morphology which added Re element was found, with the increase in the amount of Re, the pores and the second phase ion distribution changed significantly, especially when the amount of Re at 5%, TZM-Re alloy’s fracture is a mixed fracture mode which is intergranular fracture and transgranular fracture. Besides, within the local area there are grain abnormal growths, nonporous particles or impurities within the grains. The reason that grain grown mainly because of Re and Mo matrix forming Mo-Re a solid solution, so that the grains are torn and alloy before breaking bear a certain amount of plasticity changes to improve the toughness of the alloy.
