Estudio de la microestructura y resistencia a la corrosion de la aleación con memoria de forma cu-al-ni-y elaborada por fundición
Las aleaciones con memoria de forma o SMA “Shape Memory Alloys” son aquellas que tienen la capacidad de sufrir una deformación pseudoplástica y regresar a su forma inicial una vez son expuestas a variaciones de temperatura. En el presente trabajo, se realizó el estudio de la adición de Itrio como cu...

Grain Size. Descriction: The Shape Memory Alloys Are Those That Have The Ability To Undergo Pseudoplastic Deformation And Return To Their Initial Shape Once Exposed To Temperature Variations. In The Present Work
The Study Of The Addition Of Itrium As A Fourth Element In The Cu-Al-Ni Memory Alloy Manufactured By Means Of A Melting Process In An Induction Furnace Was Carried Out
For This Purpose Four Specimens With Different Percentages Were Made Of The Itrium That Were Subjected To A Microstructural Analysis By Means Of Optical Microscopy And Scanning Electron Microscopy In Order To Know The Effect Of Yttrium On The Microstructure And Grain Size Of The Alloys. Additionally
A Hardness Test And Electrochemical Electrochemical Impedance Spectroscopy Were Carried Out In A 3.5% Nacl Solution By Weight To Determine The Corrosion Resistance Of The Alloys. The Results Obtained In The Tests Carried Out On The Alloys Show That The Increase In The Amount Of Itrium In The Al-Cu-Ni Alloy Provides A Refinement In The Microstructure Grain And An Increase In Hardness. In The Analysis Of The Corrosion Resistance Of Cu-Al-Ni-Y Alloys
It Was Possible To Determine That The Sample With The Highest Resistance To Load Transfer Was The Alloy With 1% In
