## Effects of Ar-ion implantation on the surface structure of a pyrolytic graphite (PG) have been investigated by means of the laser Raman spectroscopy and X-ray photoelectron spectroscopy (XPS). The implantation was conducted to both the basal and edge surfaces, whereby the carbon lattice was des

observed etch-patterns seem to have no relation with the dislocation content of the crystals. The imphcations are discussed.

The effect of post deposition high temperature treatment of pyrolytic graphite on the room temperature flexural strength was studied for HTT between 2500 and 2700ยฐC and residence time up to four hours. Large reductions in the scatter of flexural strength values were observed. Little effect on the fl
The dynamic mechanical behavior of pyrolytic graphite (PG) (deposited at 2200ยฐC) has been investigated as a function of reactor radiation dose up to 1.8 x 10" nvt (fast). Studies made from about 100ยฐK to 800ยฐK at frequencies near 2000 c/s indicate that the dynamic modulus of as-received PG decreases
