Abstract
The four years project Platform Science and Technology for Advanced Magnesium Alloys started in September 1999 with financial support from the Ministry of Education, Science. Sports and Culture of Japan. The project members consisting mainly of Professors in Japanese Universities are going to make various efforts for the advancement of studies on magnesium alloys. The background and concept of the research project is described, and then the contents and practical activities of the group are briefly explained.

The microstructure of as-cast AZ91 alloy is complex, with the presence of Mg17(Al, Zn)12 precipitates surrounded by an eutectic phase, AlMn intermetallic particles and an α-Mg solid solution. In addition, the distribution of aluminium in the alloy was found to be heterogeneous. Under these conditions, a multiscale approach coupling global and local electrochemical measurements seems to be a promising method to study its corrosion behaviour. Results show that the multiscale approach can be used i...

Abstract The surface of magnesium particles was modified by coating with Viton as an energetic polymer using solvent/non-solvent technique. Taguchi robust method was utilized as a statistical experiment design to evaluate the role of coating process parameters. The coated magnesium particles were characterized by various techniques, i.e., Fourier transform infrared (FT-IR) spectroscopy, scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX) and thermogravimetry (TG), and ...

In this study, Al–Mg–Al trilaminated thin plates were fabricated by one-pass hot rolling to improve the processing capacity and bonding strength of magnesium alloy plates. The effects of processing parameters were investigated. The results show that the optimal bonding strength is up to 20 MPa with a reduction ratio of 40 % and rolling temperature of 400 °C, superior than that in other one-pass rolling studies with regard to thin laminated plates. In addition, a favorable property is achieved wi...

Mg-Al-Zn type mixed powder was mechanically alloyed (MA) by using a planetary ball mill under Ar atmosphere. The MA powders were sintered by vacuum hot pressing (HP). The change of constituent phase of HP materials was examined by XRD and FE-EPMA. Its mechanical properties were evaluated by Vickers hardness and compression tests. HP material was obtained by processing MA powder with mean particle size of 5.6μm at 673 K for 18 ks. Its hardness and 0.2% proof strength became HV164 and 546 MPa, res...

The aim of this paper is to report on magnesium plasma diagnostics and to investigate the properties of thin Mg films deposited on Si and glass substrates by using thermionic vacuum arc (TVA) technology. TVA is an original deposition method using a combination of anodic arc and powerful electron gun system (up to 600 W) for the growth of thin films from solid precursors under a vacuum of 10−6Torr. Due to the comparatively high deposition rate as well as comparatively high plasma potential—around...

The hydriding-dehydriding process was used to recycle AZ40 magnesium (Mg) alloy scraps, and the microstructure nanocrystallization was realized. X-ray diffraction analysis, scanning electron microscopy, and transmission electron microscopy were carried out to characterize the microstructure. After mechanically milling in hydrogen for 72 h, matrix Mg was completely turned into nanocrystalline MgH2, with an average crystallite size of about 10 nm. And then, the MgH2 phase was completely transforme...

Abstract Today’s industry aims at such situation, where number of defective products, so called defects shall approach to zero. Therefore, one introduces a various changes in technology of production, introduces improvements which would help in accomplishment of this objective. Another important factor is introduction of different type of testing, which shall help in assessment which factor has significant effect on quantity of rejects, and which one could be neglected. Existence of casting reje...

AbstractThe microstructure evolution and mechanical properties of as cast Mg–10Gd–2Y–0·5Zn–0·3Zr during heat treatments were investigated in the present study. The appropriate solution treatment temperature of 530°C for the alloy was identified. The peak tensile yield strength of 202 MPa and elongation of 4·5% are obtained in the alloy aged at 200°C for 80 h. The high strength of the peak aged alloy is mainly ascribed to the dense precipitation of 14H type long period stacking ordered phase and ...

In this study, the coating layers of IN625 and 301 stainless steel powders were deposited on the AZ80 magnesium alloy substrates by cold-spray technique. The crystal structures, cross-section of the coating layers and anti-corrosion capabilities were examined via XRD, SEM, potentio-dynamic polarization and salt spray test. Experimental results show that the coating layers have a few porosities. The AZ80 substratesexhibit a phenomenon of grain refining after the cold-spraying. Meanwhile, these co...
