H-shaped carbides precipitated in Cr-Mo-V steel were studied by electron microscopy and X-ray energy spectrometry. The results show that carbides consist of two different types, granular and needle-like carbides. The former carbide was V4C3 and the latter was Mo2C. The Mo2C precipitated on {111} habit planes of V4C3 with the orientation relationships (00.1)Mo<SUB>2C</SUB>\varparallel(\bar111)V<SUB>4C3</SUB> and [10.0]Mo<SUB>2C</SUB>\varparallel[110]V<SUB>4C3</SUB>. In this steel, various Mo2C-V4C3 carbides were observed. When V4C3 has a pair of the Mo2C needles, it is H-shaped, because the Mo2C needles grow in parallel on the opposite {111}V<SUB>4C3</SUB> planes such as (1\bar11)V<SUB>4C3</SUB> and (\bar11\bar1)V<SUB>4C3</SUB>. When V4C3 has two pairs of the needles, it shows a #-shaped feature because of the two paralleld pairs.<BR>The growing direction of the Mo2C in the matrix seemed to have some relevance to the extent of the misfit between Mo2C and matrix.<BR>It was also clarified by the creep rupture test that Mo2C-V4C3 carbides were thermally stable during the creep rupture test.
