“…From the curves obtained, it can be concluded that the selected ageing temperatures chosen were too high, since the aluminium alloy shows signs of overageing and can therefore be assigned to the T7 state. Similar conclusions were taken by Takata et al in his research [42].…”

The Influence of Shot Peening and Artificially Ageing Aluminium Alloy 7075 on Corrosion Behaviour

This paper investigates the corrosion of shot peened AA7075 aluminium alloys aged at different temperatures. The surface integrity of the hardened layer was evaluated with SEM, EDS, differential scanning calorimetry, hardness, and roughness measurements, and in the end also with corrosion resistance tests. The research results indicated that there were significant differences in precipitates distribution between aluminium alloys artificially aged at different temperatures. As the ageing temperature increases, the microhardness decreases, which influences the final roughness condition of the surface layer after shot peening. The results of potentiodynamic polarisation tests indicate that shot peening enables shifting the pitting potential to positive values, which ensures slightly higher corrosion resistance. SEM images confirmed the dissolution of the aluminium matrix near the separated iron-rich phases of the Alx form (Fe, Mn) by the action of galvanic cells.

“…This paper reported the effects of Cu or Ni additions on the precipitation of intermetallic phases in the heat-resistant aluminum alloy with a ternary composition of Al-5Mg-3.5Zn (mol%) strengthened by fine precipitates of T-Al 6 Mg 11 Zn 11 intermetallic phase. 31,32) The fourth element of Cu and Ni at 1 mol% was added to the Al-Mg-Zn ternary alloy as the modified quaternary alloy. The quaternary alloys were solution-treated at 480°C and subsequently aged at 300°C for different periods.…”

The six best papers were awarded by The Japan Institute of Light Metals (JILM) and The Japan Society for Technology of Plasticity (JSTP) in Materials Transactions. Here, the awarded papers are briefly summarized as current trends in research of Materials Transactions. Among the six best papers, three were from JILM and the two of the three were selected for young scientists whose ages are 30 or below. All the six best papers were originally published in Japanese in Journal of the Japan Institute of Light Metals and Journal of the Japan Society for Technology of Plasticity as cutting-edge research in JILM and JSTP which are major companions of Materials Transactions.

“…The Al-Mg-Zn alloy is characterized by high strength strengthened with T-Mg 32 (Al, Zn) 49 phase, which makes it a promising material for various industries, such as aerospace, automobile, and shipbuilding [1][2]. However, the strength of Al-Mg-Zn alloy is still insufficient compared with 7xxx series aluminum alloy [3], and the welding performance also needs to be improved.…”

The precipitation of secondary Al3(Sc, Zr) particles in Al-Mg-Zn-Sc-Zr alloy during the two-stage homogenization has been studied by OM, SEM, and TEM. The results indicated that Al3(Sc, Zr) particles grew gradually with the first-stage homogenization temperature ranging from 380°C to 440°C. The first-stage homogenization temperature greatly affected the particle size of Al3(Sc, Zr). The lower the first-stage homogenization temperature was, the smaller the particle size of Al3(Sc, Zr) was. After the same second-stage homogenization treatment, the particles were coarsened, and the size was 15.2 nm, 15.9 nm, and 19.7 nm, respectively. Meanwhile, the Al3(Sc, Zr) particles exhibited a legume-like morphology and maintained a coherent relationship with the Al matrix after different homogenization treatments.
