高熵合金(High Entropy Alloy) 傳統合金都是在一種或兩種主要元素的基礎上加入合金元素從而得到性能不同的合金主,元素鮮少超過三個。如鐵基合金、鈷基合金、鋁基合金等,一種原子百分比大於50 % 的主要元素,目前為人類所用的傳統合金系統有30 多種。 高熵合金也稱多主元高熵合金, 即該種合金是由多種主要元素組...
But Yeh and colleagues reasoned that, as the number of elements in an alloy increased, the entropic contribution to the total free energy would overcome the enthalpic contribution and, thereby, stabilize solid solutions (Box 1 ; Fig. 1) . They coined a catchy new name, high- entropy alloys...
Such alloys are commonly addressed as high-entropy alloy (HEA) [198]. Definition of HEA is flexible in a sense that it allows minor elemental additions with atomic percentages even smaller than 5%. However, there is another definition that states that having a configurational entropy larger than...
A prototypical, single-phase, and non-equiatomic high entropy alloy FeMnCoCrhas been mechanically deformed at room and cryogenic temperatures. Plastic deformation was accommodated via crystallographic slip at room temperature while transformation induced plasticity (TRIP) has been observed in samples ...
Single focus on high-entropy and medium-entropy materials. Brings together researchers working on metals, ceramics, semiconductors, polymers, composites and their processing and synthesis. Covers crystal structures, microstructures, structural and functional properties, applications and all their inter-relation...
