Thermal response of pure and two kinds of oxide dispersion strengthened tungsten alloys were investigated using intense pulsed ion beam (IPIB) device. Scanning electron microscope (SEM) and energy dispersive X-ray spectroscopy (EDX) were used to examine the surface modifications and the distributions of dispersion elements. By comparing the results, it is found that pure tungsten show a better resistance to thermal shock. From the perspective of the tolerance of heat load, WL10 and WYT are not recommended for PFMs.
