The microstructural path of grain-boundary-nucleated phase transformations
R.A. Vandermeer,R.A. Masumura +1 more
TL;DR: In this paper, the authors derived the microstructural path functions for transformations in which the product phase nucleates either at parent phase grain boundaries, grain edges or grain corners and grows at a constant rate.

Melting point lowering of thin metal films (Me = In, Sn, Bi, Pb) in Al/Me/Al film system
TL;DR: In this paper, the variation of the melting point of thin films (10-40nm) of In, Sn, Bi and Pb between thick (100-nm) Al films was investigated using elegant differential technique.

Devitrification behavior and glass-forming ability of Cu–Zr–Ag alloys
TL;DR: In this paper, an influence of Ag addition on the glass-forming ability and devitrification behavior of Cu-Zr glassy alloys on heating was studied by X-ray diffraction, transmission electron microscopy, differential scanning and isothermal calorimetry methods.
