It has been recognized that extrapolation from understanding of macro-particle sintering is unreliable for the nano-particle size regime. In this work, the sintering behaviour of copper nanoparticles under periodic boundary conditions at different temperatures and pressures was investigated by Molecular Dynamics simulations. It was found that smaller particle sizes, higher temperature and higher external pressure facilitate densification. Through a comparison with a two-sphere model, the governing mechanisms for many nanoparticles sintered at low temperature (T⩽900K) were identified to be a variety of plasticity processes including dislocation, twinning and even amorphization at the contact neck regions, due to the presence of high stresses.","lang":"eng"}],"publication_status":"published","publication":"Computational Materials Science","scopus_import":"1","quality_controlled":"1","title":"The sintering and densification behaviour of many copper nanoparticles: A molecular dynamics study","_id":"9676","author":[{"full_name":"Cheng, Bingqing","first_name":"Bingqing","orcid":"0000-0002-3584-9632","last_name":"Cheng","id":"cbe3cda4-d82c-11eb-8dc7-8ff94289fcc9"},{"last_name":"Ngan","full_name":"Ngan, Alfonso H.W.","first_name":"Alfonso H.W."}],"doi":"10.1016/j.commatsci.2013.03.014"}
