An investigation on plastic deformation and nanomechanical properties of Cu₆₀Zr₄₀/ Ni₈₀P₂₀ amorphous nanolaminates

Abstract

This paper aims to investigate the nanomechanical properties of amorphous nanolaminates by using the molecular dynamic (MD) simulation of nanoindentation process. To achieve this goal, two metallic glass (MG) nanolaminates with the arrangement of Cu60Zr40/Ni80P20 (CN type) and Ni80P20/Cu60Zr40 (NC type) were constructed. The MD outcomes unveiled that the NC-type sample exhibited a weaker strength at the loading stage and experienced a sharper relaxation at the end of holding stage. The strain maps of samples also revealed that the plastic deformation in the CN type initiated at the interface of substrate/indenter and was generated into the depth of material with a pear-like shape. On the other hand, the NC-type sample showed an accumulation of strain at the top layer normal to the direction of indenting process. This result indicated that the plasticity evolution occurred with a homogenous mode in the bulk of CN-type nanolaminate.

Nanofertilizers: Transforming Agriculture for Sustainable Food Production

“…Various kinds of hybrid nanofertilizers, which include nano-encapsulated and nanobiofertilizers, are gaining traction for his or her potential to improve soil health and decorate nutrient uptake in plant life. Utilizing montmorillonite, potassium chloride, urea phosphate, and urea, scientists created a high-strength spherical nanocomposite fertilizer in [15]. Polyphosphate-montmorillonite nanocomposites with improved characteristics were reported to be formed, according to characterization methods that included FT-IR, XRD, SEM, TEM, TGA, and XCT.…”
