    Abstract:

    Titanium-Zirconium-Molybdenum (TZM) alloy as the plasma facing material (PFM) will continue to be used in large quantities in the Experimental Advanced Superconducting Tokamak (EAST) device. Research and analysis of heat absorption ratio of TZM will have high reference for the later selection of PFM. In this paper, the heat absorption ratio of TZM in rolled and forged state is tested by the e-beam device of Shenzhen University, and the relevant experimental results were analyzed. It shows that the heat absorption ratio of TZM in both rolled and forged state is about 0.7, and it is not affected by the change of cooling effect and high temperature of the material. This work will be very helpful in judging the safety of TZM, which is important for long-term development of EAST. And it will also have important reference for the future construction of CFETR.
