Such laser treatmenthas causedcrystallization of tungsten and tungsten 's transformation into poly - crystalline tungsten
The proton pulses are subsequently directed down one of two beam lines to two separate target stations , where they strike solid tungsten rodscausingneutrons to be driven off from the nuclei of the tungsten atoms
The change in fracture mechanismtherefore causesa sharp ductile to brittle transition in Charpy impact energy
alloys of more than 25 % of V or Tawould leadto brittle to ductile transition from pure tungsten
Experiments with doping around 1913 had showncausedtungsten filaments to recrystallize to form very small crystals
