Effect of Ni on Amorphization of Ti-Cu-Ni Ternary alloys Prepared by Mechanical alloying
Amorphous alloys has been taken into consideration because of their unique properties and are nominated as the future engineering materials. In this research, the effect of Ni and milling time on amorphization process and thermal stability of Ti50Cu50-xNix(x=10, 15, 25 at%) alloy system were investigated. The evolution of amorphization during milling, thermal stability and subsequent heat treat...
متن کاملComparison among the local atomic order of amorphous TM - Ti alloys ( TM = Co , Ni , Cu ) produced by Mechanical Alloying studied by EXAFS
the date of receipt and acceptance should be inserted later Abstract. We have investigated the local atomic structure of amorphous TM-Ti alloys (TM = Co, Ni, Cu) produced by Mechanical Alloying by means of EXAFS analyses on TM and Ti K-edges. Coordination numbers and interatomic distances for the four alloys where found and compared. EXAFS results obtained indicated a shortening in the unlike p...
متن کاملInvestigation on Mechanical and Electrical Properties of Cu-Ti Nanocomposite Produced by Mechanical Alloying
In this paper, Cu-Ti nanocomposite synthesized via ball milling of copper-titanium powders in 1, 3, and 6 of weight percentage compounds. The vial speed was 350 rpm and ball to powder weight ratio kept at 15:1 under Argon atmosphere, and the time of milling was 90 h. Obtained powders were studied by scanning electron microscopy (SEM), X-ray diffraction (XRD), and dynamic light scattering (DLS)....
متن کاملEFFECT OF COMPOSITION AND MILLING TIME ON THE SYNTHESIS OF NANOSTRUCTURED Ni-Cu ALLOYS BY MECHANICAL ALLOYING METHOD
Ni and Cu elemental powder mixtures containing 25, 50, and 75% at Cu were subjected to mechanical alloying in a planetary ball mill under various milling times. Structural evolution was analyzed by means of X-ray diffraction and scanning electron microscopy. Experimental results indicated that nanostructured solid solution alloy powders having homogeneous distribution of Ni and Cu were formed b...
متن کاملCharacterization of Ni - Co - PVC and Ni - Cu - PVC Alloys Prepared By Mechanical Alloying Technique ( MAT ) Riyanto and Mohamed
A study was carried out to characterize Ni-Co-PVC and Ni-Cu-PVC composite materials prepared by mechanical alloying technique (MAT) using SEM, EDS and electrochemical test. Composite materials were prepared by mixing together 95% of metal powder (Ni+Co or Ni+Cu) with 5% PVC. PVC was used as a binder and tetrahydrofuran (THF) was used as a solvent in composite material preparation. Based on the ...
