Abstract

The structural and physical properties of Cu_90 – xFe_xPd₁₀ ternary alloys with x = 5, 10, 15, and 20 are studied using X-ray diffraction, resistivity measurements, Vickers hardness tester, and tensile testing machine. The samples were prepared by using arc-melting furnace under an atmosphere of purified Argon. The integrated intensity data obtained from X-ray diffraction are used to determine microstructure and hence lattice parameter. The lattice parameter has shown a negative deviation from Vegard’s rule. The addition of Fe in Cu_90 – xFe_xPd₁₀ alloy improves the structure, and increases the electrical resistivity and the hardness of alloy. With the addition of Fe, the mechanical properties of alloy such as ultimate tensile strength, Young’s modulus, and elongation are decreasing, while the elastic limit is increasing.

Fe对x = 5、10、15和20的Cu 90 – x Fe x Pd 10三元合金的组织和物理性能的影响

摘要

使用X射线衍射，电阻率测量，维氏硬度计和拉伸试验机研究了x = 5、10、15和20的Cu _{90 –  x} Fe _x Pd ₁₀三元合金的结构和物理性能。通过在纯氩气氛下使用电弧熔化炉制备样品。从X射线衍射获得的积分强度数据用于确定微观结构，从而确定晶格参数。晶格参数显示出与Vegard规则的负偏差。在Cu _{90 – x} Fe _x Pd _10中添加Fe 合金改善了组织，增加了电阻率和硬度。随着Fe的添加，合金的机械性能如极限抗拉强度，杨氏模量和伸长率下降，而弹性极限增大。
