Potential energy of an alloy is essential indicator for evaluating the stability structure in predicting new materials. Therefore, how to calculate potential material design has become inevitable problem. While first-principles calculations can provide chemical accuracy arbitrary atomic arrangements, they are prohibitive terms computational effort and time. To enable atomistic-level simulations...

Plane-strain machining can be used to impart large plastic strains in alloys that are difficult to deform by other severe plastic deformation (SPD) processes. By cutting at low speeds, the heating caused by friction with the tool can be reduced to insignificant levels. The utility of this approach for characterizing microstructure development in SPD is demonstrated using a variety of commercial...

Precipitation hardening, or age hardening, provides one of the most widely used mechanisms for the strengthening of metal alloys. The fundamental understanding and basis for this technique was established in early work at the U. S. Bureau of Standards on an alloy known as Duralumin [1,2]. Duralumin is an aluminum alloy containing copper and magnesium with small amounts of iron and silicon. In a...

Atomic-resolution electron microscopy reveals that pillarlike silicon double columns exist in the hardening nanoprecipitates of AlMgSi alloys, which vary in structure and composition. Upon annealing, the Si2 pillars provide the skeleton for the nanoparticles to evolve in composition, structure, and morphology. We show that they begin as tiny nuclei with a composition close to Mg2Si2Al7 and a mi...

WEDM is one of the important variants of electrical discharge machining (EDM) which uses the thermal energy generated between the electrodes for machining the electrically conducive materials. This method has been successfully implemented in common materials like aluminum, stainless steel etc., But its application in super alloys like Ti6Al4V is still under investigations. This paper reviews th...
