Abstract

The effect of minor-Cu addition and thermomechanical treatment on the microstructure and properties of Al-Fe alloy was investigated by means of optical microscopy, SEM, tensile test, and conductivity measurement. The results show that Cu was evenly distributed in the matrix of as-cast Al-Fe-Cu alloy, while the Fe segregated at grain boundary. After extrusion the properties of Al-0.7Fe-0.2Cu alloy reached the optimum, the conductivity was 59.90% IACS, the tensile strength was 108 MPa, and the hardness was 31.2HV. The tensile strength of Al-0.7Fe-0.2Cu alloy decreased sharply with the increase of annealing temperature. The tensile strength was the lowest (100 MPa) after annealing at 400℃, while the elongation was the highest (31.3%). The peak electrical conductivity of Al-0.7Fe-0.2Cu alloy was 62.61% IACS after annealing at 250℃. In addition, many fine needle-like θ(Al₂Cu) phase precipitated during annealing in Al-0.7Cu-0.2Cu alloy, which interacted with dislocations. With the increase of annealing temperature, dislocation density decreased and grain refinement occurred.

Key words: Al-Fe-Cu alloy tensile strength electrical conductivity elongation θ (Al₂Cu) precipitate
