Electrolytic preparation of Mg-Al-La alloys in KCl-MgCl2-AlF3 molten salts

EXPERIMENTALl ANALYSIS OF PARTITION COEFFICIENT IN Al-Mg ALLOYS

Because the partition coefficient is one of the most important parameters affecting microsegregation, the aim of this research is to experimentally analyse the partition coefficient in Al-Mg alloys. In order to experimentally measure the partition coefficient, a series of quenching experiments during solidification were carried out. For this purpose binary Al-Mg alloys containing 6.7 and 10.2 w...

Precipitation Hardening of Al–Si–Mg Alloys

Melt Protection of Mg-Al Based Alloys

This paper reports the current status of Mg melt protection in view to identify near-future challenges, but also opportunities, for Mg melt protection of Mg-Al based alloys. The goal is to design and manufacture sustainable Mg alloys for resource efficiency, recycling and minimising waste. Among alternative cover gas technologies for Mg melt protection other than SF6: commercially available tec...

Preparation of the TiB2 coatings by electroplating in molten salts

The improvement of titanium diboride (TiB2) coatings over the molybdenum substrate was investigated by comparing the electrochemical techniques of continuous current plating (CCP) and periodically interrupted current (PIC). The solvent used was a eutectic Flinak mixture (LiF–NaF– KF, 46.5:11.5:42molar ratio) with solutes K2TiF6 andKBF4 with the electrochemically-active components in themolar ra...

THERMAL ANALYSIS AND KINETICS OF THE PRECIPITATION IN WROUGHT Al-Mg, Al-Mg-ScAND Al-Mg-Sc-Me (Me=Zr, Ti) ALLOYS

Precipitation behaviour of wrought Al-6Mg alloys with ternary scandium and quaternary zirconium and titanium has been studied. Hardness measurements and resistivity studies are employed to assess the precipitation behaviour of scandium doped Al-6Mg alloy without or with quaternary additions of zirconium and titanium. Further, the kinetics of precipitations are studied by differential scanning c...
