“…Aside from "static" microstructure features, interdiffusion or intermixing prior to phase transformation, and associated concentration gradients play a key role in determining the phase formation kinetics [1,2]. It is well known that severe plastic deformation can induce significant mixing, as in ball milled powders [3][4][5][6][7]. Similar features have also been reported for torsion under high pressure [8] and cold rolling [9].…”

Al/Ni multilayers have been prepared by repeated folding and cold rolling (F&R) of elemental foils. The thickness of Al and Ni foils is reduced down to less than 50 nm after fifty F&R cycles. Three-dimensional atom probe analyses clearly reveal the presence of supersaturated solid solutions and give the evidence of deformation-induced intermixing. The formation of the solid solutions and their transformation into the Al 3 Ni phase upon annealing is discussed.

“…The addition of minor Al quantities (up to 10 at%) to the Cu-Zr glassy alloys may improve their thermal stability, mechanical properties and glass forming ability (GFA) [5,6]. Glassy alloys can be produced by casting and by solid state techniques such as mechanical alloying (MA) [7][8][9][10]12] or mechanical milling (MM) [8,[11][12][13]. Both solid state techniques have now been shown to be capable of synthesizing a variety of equilibrium and nonequilibrium alloy phases starting from blended elemental or prealloyed powders.…”

Abstract:The microstructure evolution during mechanical milling was studied in the CuZrAl system. The compositions lay on the two liquidus surfaces indicating different solidification processes in the three alloys. Cu(55-x)Zr(35+x)Al10 (x = 0; 5; 10 at%) master alloys were produced by arc melting. After identification of the phases, the master alloys were milled for 25 hours and amorphous/crystalline powders were synthesized. The master alloys contained Al21Cu28Zr51, AlCu2Zr, CuZr and traces of Cu10Zr7 phases in different volume fractions. The optimal milling time was determined to be 15 hours based on the results of X-ray diffractometry (XRD) and differential scanning calorimetry (DSC) examinations. The 5 h milled powder contained CuZr and Al21Cu28Zr51 phases, which diminished due to further milling resulting in amorphous matrix composite with nanosized Al21Cu28Zr51 phase. The thermal stability of the samples was investigated by DSC. The peak temperatures of the first crystallization process of the as-milled powders shifted as function of milling time and polynomial curves were fitted to the measured points.

“…Developing solid solubility is dependent on the temperature. According to [27] that the Cr powder has higher thermal resistance and it used as coating material. Therefore, the significant effect of the Cr powder in the Fe 80 Cr 20 alloy is shown when ball milling process.…”

“…The increasing of kinetic energy allows the solvent molecules are more effective to break apart the solute molecules that are held together by intermolecular attractions. The solid solubility was investigated by [14,15,27] that the ball milling effective to develop solid solubility of Cr to Fe powder because the high energy kinetics and the balls slugging the sample powder during ball milling process.The solid solubility when ball milling process is increased because the diffusion of the component atom increased. It is caused by larger volume friction of the atom samples in the grain boundaries [27,28].…”

Abstract. -Fe-Cr phase was investigated using formula Fe 80 Cr 20 . Ball milling process and ultrasonic technique is successfully done to develop solid solubility and improve homogenous, respectively. However, the effect of the Cr to Fe powder is not complete investigated using combination of its process. Ball milling is conducted by milling time of 60 hours and ultrasonic technique were carried out at ultrasonic time of 3 h, 3.5 h, 4 h, 4.5 h and 5 h. From the strain effect analysis is obtained that the strain increased with crystallite size decreased and broad peaks due to the micro strain that is obtained from the increasing d-spacing. The solid solubility and lattice parameter of the material relatively increased from the untreated sample to treated samples with the highest solid solubility of 62.1% and highest lattice parameter of 3.091 nm which is located at the milled and UB 4.5 hours. It is caused the temperature increased that effect to the higher diffusion of the atom. Therefore, the combination treatment is highest promote to improve the properties of the metallic materials.
