ed 9Cr– 1Mo steel (ASME Grade 91) and 316L stainless steel in a liquid metal reactor. In order to overcome the technical problems and take full advantage of the properties of different metals, it is necessary to pay more attention to the joining of dissimilar metals, so as to produce ...
Another matter of concern is the flash and false setting of the binder due to its poor hydration. The presence of Zn and a high alkali content (Na, K) in the WG powder can trigger the flash setting of the binder [66]. A proper w/c ratio (0.45–0.50) can positively influence the ...
