Xin Chemistry ACS Catalysis 2024 Low platinum-group-metal (PGM) ordered intermetallic catalysts have been considered one of the most promising candidates for catalyzing the oxygen reduction reaction (ORR) in … WebFeb 26, 2011 · Abstract. This paper summarizes recent research on intergranular fracture and alloy design of L1 2 ordered Ni 3 X intermetallics. The grain boundaries in Ni 3 AI, Ni 3 Ga, Ni 3 Si, and Ni 3 Ge are intrinsically brittle, and boron additions are effective in ductilizing the first three alloys but not in Ni 3 Ge The beneficial role of boron is to ...
