摘要：
Previous study by Queudet et al. [1] showed that powder metallurgy allows to produce high strength ultrafine-grained (UFG) Al-Zn-Mg alloys which contains both eta' and eta phases. This present work investigates the effects of solid solution treatment followed by quenching (W temper) and subsequent ageing to obtain theoretical T6 tempered UFG material. TEM analyses revealed the presence of GP zones and metastable eta' phase in W tempered UFG material. Compared to as-fabricated material, quenching conferred to the alloy higher maximum stress of 785 MPa and stabilized plastic flow. Further ageing resulted in over-aged alloy containing the eta phase, inducing lower hardness and compressive stress. TEM observations showed that variant eta(2) which grows from eta' is delimited by previous GP-II zones.
