the effect of ball milling and fatty acid addition on the properties of mgb 2 wires carlos laliena, elena martnez, luis alberto angurel and rafael navarro abstractimproved inductive critical current density, j c, at medium and high magnetic fields, b, has been obtained in mgb 2 wires made from ball milled and carbon doped precursorsRead More
the coercivity was increased with increased ball-milling time, while the saturation induction showed a peak value after 1 h of ball-milling and then decreased with further ball-milling. raman spectra of the composite indicated that no serious damage had been imparted to the cnts during ball-millingRead More
ball milling bm is a well-established technique for producing different materials in powder shape. dynamical analysis of bm helps to optimize the process through simple but general relations e.g., definition of an equivalent milling time. concerning the field of study of magnetocaloric effect mce, bm is in different ways as a single step process mechanical alloying, as an initialRead More
carbon nanotubes cnts reinforced feco alloys were produced by high energy ball-milling and spark plasma sintering sps. cnts distribution in the feco alloy was gradually improved as ball-milling time increased, with a uniform dispersion achieved after 6 h ball-milling. tensile tests demonstrated that, as the ball-milling time increased, the yield strength increased in the compositesRead More
