Resistivity and strength of precipitation-hardened dilute AlAu alloys Academic Article uri icon


  • High purity aluminum is often favored over copper for superconductor stabilizer applications because of a lower resistivity and a lower magnetoresistance effect in high magnetic field. This preference coupled with the major disadvantage of aluminum, namely its lower strength, led to the study reported here on dilute AlAu alloys. This alloy is strengthened dramatically by a precipitation heat treatment and exhibits low resistivity in the aged condition. Experiments are reported on the yield strength and residual resistivity of dilute AlAu alloys. Several schemes are developed that allow the conductor design engineer to trade off resistivity and strength. A method of optimizing alloy strength-resistivity is presented. 1981.
