As the Fe element increased by 0 and 0.75wt.%, the phase fraction increased to 5.05, 5.76, 7.14 and 7.38 %. The increased intermetallic compound increased the driving force for recrystallization and grain refinement. The electrical conductivity of Al-1.0 wt.%RE alloy with Fe addition decreased to 60.29, 60.15, 59.58 and 59.13 %IACS. With an increase in the Fe content from 0 to 0.75 wt.% the ultimate tensile strength (UTS) of the alloy increased from 74.3 to 77.5 MPa. As the mechanical properties increase compared to the reduction of the electrical conductivity due to Fe element addition, it is considered to be suitable for fields requiring high electrical conductivity and strength.}, type={Article}, title={Effect of Fe Content on the Mechanical Properties and Thermal Conductivity of the Al-RE Alloys}, URL={http://www.czasopisma.pan.pl/Content/116377/PDF/AMM-2020-3-10-Hyeon-Taek%20Son.pdf}, doi={10.24425/amm.2020.133212}, keywords={aluminum, extrusion, Rare Earth, thermal conductivity, mechanical property}, }
