Phase metamorphosis of Ag – Cu amalgamation nanoparticle bedded in Ni matrix

In the present study, colorful( Ag – Cu) nanoalloy patches are bedded in the Ni matrix and synthesized by rapid-fire solidification, videlicet Ni –3.8 at.( Ag77 – Cu23), Ni – 4 at.( Ag60 – Cu40), and Ni –4.8 at.( Ag24 – Cu76), to understand the effect of matrix on nanoparticles. The detailed TEM study reveals that Ni –3.8 at.( Ag77 – Cu23) and Ni – 4 at.( Ag60 – Cu40) show a single phase of( Ag), while Ni –4.8 at.( Ag24 – Cu76) indicates the presence ofbi-phasic( Cu) –( Ag) amalgamation nanoparticles. likewise, thermal cycling was carried out using DSC to study the influence of solid- result parcels. Unlike Ni –3.8 at.( Ag77 – Cu23) and Ni – 4 at.( Ag60 – Cu40), Ni –4.8 at.( Ag24 – Cu76) shows no changes while melting and cooling. Further, in situ TEM disquisition of Ni –4.8 at.( Ag24 – Cu76) nanoparticle reveals that thebi-phasic nanoparticles suffer completely solid- state metamorphosis to single- phase( Ag) nanoparticles previous to melting while heating. Theoretical studies on the phase stability of Ag – Cu – Ni at the nanoscale were accepted to validate the experimental results, offering sapience into the phase change of these solid- result nanoparticles in the Ni matrix.
