Mechanism of Unstable Material Removal Modes in Micro Cutting of Silicon Carbide

Micromachines, 2019
This study conducts large-scale molecular dynamics (MD) simulations of micro cutting of single crystal 6H silicon carbide (SiC) with up to 19 million atoms to investigate the mechanism of unstable material removal modes within the transitional range of ...

Ductile-brittle transition mechanism of SiC particle-reinforced Al-MMCs under ultrasonic assisted grinding with single grain

Journal of Materials Research and Technology
High volume fraction (45 %) silicon carbide particle-reinforced Al matrix composites (SiCp/Al-MMCs) play an important role in various engineering fields due to their excellent properties, but the high hardness and brittleness of the SiC reinforcements ...

The influence of sliding velocity and temperature on the ductile-to-brittle transition in asperity-level wear: A molecular dynamics study

Friction
During sliding contact, asperities may undergo either ductile smoothing or brittle fracture, producing debris. A critical junction scale, d∗, governed by material properties, dictates this transition.
