Effect of Minor Co Substitution for Ni on the Glass Forming Ability and Magnetic Properties of Gd_(55)Al_(20)Ni_(25) Bulk Metallic Glass

         

摘要

Element substitution is usually used to improve the glass forming ability(GFA)and magnetic properties of alloys.We obtain Gd_(55)Al_(20)Ni_(20)Co_(5) bulk metallic glass(BMG)by minor Co substitution for Ni in the Gd_(55)Al_(20)Ni_(25) glass-forming alloy.The Gd_(55)Al_(20)Ni_(20)Co_(5) BMG exhibits a better GFA and magnetocaloric effect(MCE)than the Gd_(55)Al_(20)Ni_(25) BMG.The mechanism for the enhanced magnetic entropy change and refrigeration capacity of the Gd_(55)Al_(20)Ni_(20)Co_(5) BMG is investigated.
