To make fusion reactors, we need materials that can withstand its punishing environment, and a new Chinese-made material can survive reactors’ intense conditions.

For decades, fusion projects such as the International Thermonuclear Experimental Reactor (ITER) have relied on 316LN or JK2LB cryogenic stainless steels. Those alloys hold up well at liquid-helium ...

ORNL researchers used a laser powder-bed system at the lab’s Manufacturing Demonstration Facility to 3D print 316H stainless steel capsules for use in irradiation experiments. The capsule provides a ...
