논문 초록 (Abstract)
The oxidation behaviors of Mo rich alloys have been investigated in the Mo-Si-B ternary system. Seven selected alloy systems composed of two phase alloys (Mo (solid solution) + T2 (Mo5SiB2) and three phase alloys (Mo (solid solution) + T2 (Mo5SiB2) + Mo3Si) have been fabricated by arc melting elemental components. Mechanical behaviors of the selected alloy systems have been investigated in order to identify the effect of composition on the ternary system. Also, oxidation tests have been performed in order to identify the oxidation behaviors at 1 073 and 1 373 K. When the alloy compositions move towards the Mo side, the oxidation reactions were accelerated for the two phase alloys due to the presence of Mo (s. s.), while the tendency of oxidation was not fast for the three phase alloys. The oxidation behaviors at above and below 1 273 K have been discussed in terms of microstructural observations during oxidation tests.
