High temperature fracture toughness and fatigue behavior of Ti-Zr-Mo and W-Re alloys for X-ray tube application
Abstract
Commercial x-ray targets for computed tomography (CT) applications consist oftwo major components, a metal disc made of the titanium-zirconium-molybdenum (TZM)alloy, and a surface layer in the bombarding region made of the tungsten-rhenium (W-Re)alloy. The target must endure extremely high temperature, associated with high thermalstress, and mechanical stress due to the centrifugal force induced by high speed rotationof the target. Therefore, studies on high temperature fracture and fatigue behavior of thesematerials would be the most important for reliability assessment and safety design of the x-raytarget. However, they have been rarely reported and high temperature fracture and fatiguebehavior of these materials has been not always clarified.In the present study, high temperature fracture toughness was evaluated for twokind of TZM alloys, one with higher C content and the other with higher O content.Moreover, effect of forging rate on high temperature fracture toughness was discussed.Fatigue properties at room temperature and 1000 °C were evaluated for three kinds ofmaterials, layered W-Re/TZM, bulk W-Re and bulk TZM, and a fatigue failure definitionin the high temperature fatigue test was investigated to evaluate high temperature fatiguestrength. The fatigue processes of these x-ray target materials at high temperature werealso investigated.High temperature fracture toughness of two TZM alloys with different kinds ofgrain boundary particles was successfully evaluated using the convenient JIC test method.
