Atomic-scale analysis of drawing behavior in FeNiCr alloys with different crystal orientations and Bi inclusions

Haochen Wang, Fazhan Wang, Xiaopeng Li, Lujia Yu et autres

Abstract This study employed molecular dynamics (MD) simulations to investigate the effects of crystal orientation and bismuth nanoparticles on the mechanical properties and microstructure of FeNiCr alloy during drawing. MD models of single-crystal FeNiCr alloy with four crystal orientations—[100], [110], [120], and …

Comparative analysis of anisotropy between single crystal and polycrystalline Bi-containing free-cutting steels under nanoindentation: a molecular dynamics study

Lujia Yu, Fazhan Wang, Yuan Fan, Xiaopeng Li et autres

Abstract This study employed molecular dynamics (MD) simulations to investigate the effects of Bismuth (Bi) inclusions on the anisotropy and microstructural evolution of FeNiCr alloy (a model for Bi-containing free-cutting steels) during nanoindentation. Single-crystal systems with [100], [110], [111] orientations and polycrystalline …

Self‐Propelled and Long‐Time Transport Motion of PVC Particles on a Water Surface

Lei Wang, Bin Yuan, Jinrong Lu, Sicong Tan et autres

Driven by the Marangoni effect, a poly(vinyl chloride) (PVC) particle runs in its orbit (a) with high velocity due to the release of surfactant and heat. The PVC particles are also able to efficiently drive an aluminum bulk and to induce spinning …
