Artificial_Micrometeorites [PDF]

open access: yesarXiv, 2014
An iron ball, a beryllium sphere and a tungsten tube segment with diameter twenty microns, are electrically charged while proton beam irradiating. These bodies are accelerated by the running pulse field in a spiral waveguide up to velocity: thirty kilometers per second.

Welding consumable research for compacted graphite cast iron

open access: yesJournal of Materials Engineering, 1991
Research has developed a new consumable material for gas welding of compacted graphite (CG) cast iron. The effects of C, Si, RE (rare earth), Ti, Al and weld cooling rate on graphite and matrix structure of compacted graphite cast iron welds have been studied. The optimum C, Si, RE and Ti contents of the weld metal were determined.
