The sintering kinetics of CoCrMo powders is investigated by dilatometry. Pre-alloyed spherical powders were axially compacted and sintered between 1300°C and 1375°C. SEM images coupled to an EDS ...

Cosmic rays (CRs) are accelerated in diverse astrophysical objects like supernova remnants, massive star clusters, or pulsars. Fermi acceleration mechanisms built a power-law distribution controlled ...
