  1. According to the nb - si phase diagram, the temperature of 1550 ?, which is lower than the eutectoid transformation temperature of nbssi ( 1783 ? ), is chosen for heat - treatment. according to the present conditions of the furfaces, heat - treatment by stages is first proposed for the nb - si system intermetallic composites to keep the furface in good conditions. the results indicate that the equilibrium nb + nbssia dual - phase microstructure of the nb - si system intermetallics forms gradually via such eutectoid reaction as nbasi ? nb + nbssis with the heat - treatment time

    根據nb - si二元相圖,選擇略低於nb _ 3si共析轉變溫度t _ f = 1783的1550對鑄態nb - si系金屬間化合物進行不同時間( 25h - 100h )的熱處理,並根據目前國內和我院熱處理爐的現狀,首次提出採用分段熱處理的方法來解決nb - si合金熱處理溫度高、連續熱處理時間過長而影響熱處理爐壽命的困難。
