Reliable thermodynamic descriptions of the Si-based Sr-Al-Ca-Fe-Mg metal system and SiO2-SrO-CaO-MgO-Al2O3 oxide system are essential for the understanding and optimizing the production of Si-Sr alloys. Phase relations of all SrO containing binary an

Phase equilibrium between the α-Nb5Si3 and β-Nb5Si3 phases has been studied in the Nb–Mo–Si ternary system. The high temperature β-Nb5Si3 phase is stabilized by Mo additions to yield a relatively narrow α/β two-phase field in the Nb–Mo–S

With the discovery of a number of new classes of bulk glass forming alloys that can achieve full vitrification in sizes of the order of millimeters to centimeters, there is a need to identify methods for the fabrication and joining of components. Fro

An iron-based amorphous metal, Fe49.7Cr17.7Mn1.9Mo7.4W1.6B15.2C3.8Si2.4 (SAM2X5), with very good corrosion resistance has been developed. This material was prepared as a melt-spun ribbon, as well as gas atomized powder and a thermal-spray coating. Du

Solidification microstructure evolution is a function of both alloy composition and thermal history. With a wedge-shaped mold, castings can be subjected to a range of cooling rates differing by orders of magnitude, typically 101–103 K/s, in a singl

New corrosion-resistant, iron-based amorphous metals have been identified from published data or developed through combinatorial synthesis, and tested to determine their relative corrosion resistance. Many of these materials can be applied as coating
