BK X-ray spectra from mechanically alloyed (MA) Ti-hBN powders were measured precisely using an electron probe microanalyzer (EPMA), in order to investigate the reaction progress of this system. Their spectra features were discussed in comparison with mechanically ground (MG) hBN oowders.<BR>At the early stage of MA, the main BK band at 6.9nm was almost unchanged, while 6.5nm satellite peak intensity was increased. From the result of milling of hBN alone, it was considered that hBN was changed into amorphous BN (aBN) in consequence of refinement, but B state of this aBN was still remained as same as that of hBN. BK spectra of 144ks MA powder was clearly different from that of TiB<SUB>2</SUB>, in spite of the observation of TiB<SUB>2</SUB> by X-ray diffraction measurement. This spectrum was in good agreement with the combined spectrum with aBN and TiB2 spectrum. In conclusion the excess of B was remained still as aBN after 144ks MA.
