An Effect of Thermocycling under Loading upon the Structure Changes of Dispersion-Strengthened Aluminium Alloys

摘要

A structural state of the dispersion-strengthened aluminium alloys Al-Cu and Al-Zn after thermocycling under the external stretching loading, which adds up to 0.2÷0.6 part of the yield stress was analysed by methods of mechanical spectroscopy, metallographic examination, and microhardness.
