The internal friction and precipitate phases of the deformed Fe-P-N alloys have been investigated. It has been found that the ratio of depends on the content of P and the relation holds if the content of N is lower than 30wt.ppm and the content of P is lower than 640wt.ppm. It shows that the interce...

BORON ISOTOPE FRACTIONATION DURING PROLONGED ION-BOMBARDMENT

Chinese Physics Letters

Dynamic Monte Carlo simulation is used to explore the B isotope sputtering during 1 ke V Kr ion irradiation. It is found that at both zero and high fluences the light isotope is preferentially ejected in the near-normal direction; meanwhile, there is a low fluence (1.4...
