Effect
Of Tellurium Addition On Thermo-Mechanical Characterization And
Shape Memory Properties For Cu-Al-Ni Shape Memory Alloys |
This
paper aims to study the effect of Trillium on Thermo -Mechanical
characterization by add Te with three different weight
percentages (0.3%, 1%, 3%) to a Cu-14%Al-4.5%Ni Shape Memory
Alloy which prepared by casting method in vacuum induction
furnace. Many tests and inspections such as optical and SEM
examinations , DSC Measurement ,XRD inspection , compression and
Vickers hardness tests were investigated. The results showed
that there is an increase in the transformation temperatures,
shape memory limits and anincrease hardness and decrease in
Young Modulus Also it was found that at0.3%wt Te gave better SME
properties and Mechanical properties Due to the formation of
both Austenite phases and martensitic phase and Te particles
distribution in martensite matrix of SMA. Keywords- Shape Memory
Alloys. |
