Evolution and structural transition of quasicrystalline phases in Al-Fe-Cu-Cr and Al-Fe-Cu-Mn alloys during high energy ball milling

Yadav, T.P.; Mukhopadhyay, N.K.; Tiwari, R.S.; Srivastava, O.N. (Institute of Physics Publishing, 2010)

The main objective of the current work was to investigate the transformation mechanism in quasicrystals during mechanical alloying/milling. The quasicrystalline phases have been synthesized by melting the individual elements ...
Inverse Hall Petch Like Mechanical Behaviour in Nanophase Al Cu Fe Quasicrystals

Mukhopadhyay, N.K.; Ali, F.; Scudino, S.; and et. al. (Polska Akademia Nauk, 2014-08)

The structural and mechanical stability of quasicrystals are important issues due to their potential for possible applications at high temperatures and stresses. The aim of the present work is, therefore, to review the ...
Stability of mechanically alloyed Al70Cu15Ni 15 alloy during annealing

Yadav, T.P.; Mukhopadhyay, N.K.; Tiwari, R.S.; Srivastava, O.N. (Institute of Physics Publishing, 2010)

A nano τ3 vacancy-ordered phase in the Al-Cu-Ni alloy system has been synthesized with a composition close to Al70Cu 15Ni15 by mechanical alloying a mixture of elemental powder in a high-energy ball mill by varying milling ...
Synthesis of nanocrystalline spinel phase by mechanical milling of Al-Cu-Fe and Al-Cu-Cr-Fe quasicrystalline alloys

Mukhopadhyay, N.K.; Yadav, T.P.; Tiwari, R.S.; Srivastava, O.N. (Oldenbourg Wissenschaftsverlag, 2008)

In the present study, a low-temperature synthesis of (Cu,Fe)Al 2O4 and (Cu,Cr,Fe)Al2O4 spinels from the quasicrystalline phases was investigated with the variation of process parameters during milling and annealing. The ...
