Consolidation of Cu58Zr42 amorphous/nanocrystalline powders by PM

Amorphization of CuZr Based Alloy Powders by Mechanical Milling

“…For all the samples studied in this work, 25 hours were selected as maximal milling time. This time was chosen based on the results of our previous research [16], which is sufficiently long to reach a structure transformation, but short enough to avoid the impurities from the milling balls and vial. The diffraction peaks attributed to the crystalline phases considerably reduced with increasing milling time.…”

“…The master alloys were grinded and fractioned to a particle size below 300 µm for ball-milling. The mechanical milling was performed in a Pulverisette 5 high-energy ball-mill in argon atmosphere using stainless steel vial and balls with a diameter of 5, 7 and 10 mm [16]. The overall process lasted 25 h. The milling process was interrupted every hour.…”

Microstructure evolution in CuZrAl alloys during ball-milling

“…The master alloys were grinded and fractioned to a particle size below 300 m for ball-milling.

“…This time was chosen based on the results of our previous research [21], which can be sufficiently long to reach a structure transformation, but short enough to avoid impurities from the milling balls and vial. The progress of amorphization was examined by XRD.…”

Tribocorrosion Behavior of Nanocrystalline Metals — a Review

“…Up to now, the main preparation methods of nanocrystalline metal materials contains in-situ compaction, 1) mechanical milling/alloying, 13,14) severe plastic deformation, 15) electrodeposition, 16) powder metallurgy 17) and amorphous alloy crystallization. 18) The in-situ compaction method is the earliest way to prepare nanocrystalline metals.…”
