The clustering of helium in bcc (body centered cubic) iron and the growth of a helium bubble are simulated at the atomistic level for the helium-rich vacancy-poor condition. It is shown that a 1/2 < 111 > dislocation loop is formed as a sequential collecti ...
Micromechanics is a booming research area experiencing the development of new advanced testing methods at small dimensions A relatively young but very popular technique involves uniaxial compressing micrometer and sub-micrometer sized objects, usually in t ...
A semi-empirical potential for ferromagnetic bcc iron that also models the co-linear magnetic moment of each atom, has been applied to clusters and surfaces. Surface energies of low index facets, surface relaxation and magnetic moment are calculated and co ...
Tensile properties and microstructure of Danocrystalline electrodeposited Ni at temperatures between room temperature and 330&DEG; C are presented. Above 300&DEG; C low flow stress and high tensile elongation are observed along with grain growth and segreg ...
