nickel-gallium-iron alloyphase diagramThe use of electrolytic deposition for hardening cutting tools from high-speed steel R6M5 is considered. The composition of the electrolyte is chosen so as to provide the formation of a composite borosulfocarbonitride layer on the cutting tool (cathode). A ...
The primary structure constitutes an aluminium alloy thrust tube, stiffened by stringers, and a pair of V-band interfaces that make MiniSIL compatible with almost all launch vehicles in use today. The use of a load bearing structure allows the satellite to be launched in astacked configurationas...

Because lithium is the least dense elemental metal, materials scientists and engineers have been working for decades to develop a commercially viable aluminum-lithium (Al-Li) alloy that would be even lighter and stiffer than other aluminum alloys. The first two generations of Al-Li alloys tended ...
Computational thermodynamics, or Calculation of Phase Diagram (CALPHAD) methods have proven useful in applications to modeling a variety of alloy properties. However, the methods are only as accurate as the thermodynamic databases they use, and two commercial thermodynamic databases exist for aluminum a...
(at about 300mV more negative than pure lithium) in the range of stability of theβ-phase (≈7–47 atoms per cent of lithium), thus implying a constant lithium activity in the alloy surface. At concentrations greater than 47 atoms per cent, the lithium activity becomes strongly composition-...

This composition range almost meets the homogeneity range of bcc (disordered state) in the Fe–Al binary phase diagram. The present work aims to investigate the dependency of corrosion resistance in a sulfuric acid upon aluminum content of the Fe–Al alloy with bcc structure, and determine the ...
phase diagram as appearing in metallurgical references. Preferred among these alloys for bearing purposes because of its combination of lubricity and structural strength is the alloy that contained about 8.5% lead. This alloy requires a temperature of at least 900° C.(1677° F.) to attain ...
