| 摘 要： | The nature and growth of the interaction layers between solid Nb and liquid Al has been studied by carrying out the tests on Nb(s)-Al(l)and Nb(s)-Al(l)-Ni(s) reaction couples isothermally reacted between 700℃and 900℃for different time intervals.It has been found that the interaction layer between Nb and Al contains two parts:a thin continuous layer of NbAl3 adjacent to the Nb surface and a two-phase zone constituted of NbAl3 particles dispersed in an Al matrix.Although the nature and growth of interaction layers follows the sour-stage mechanism,a typical cruciform pattern does not occur in Nb(s)-Al(l) reaction couples.However,a cruciform pattern was observed in Nb(s)-Al(l)-Ni(s)reaction couples.The movement of NbAl3 particles is important to the production of cruciform pattern in the reaction couples.

| Abstract: | The nature and growth of the interaction layers between solid Nb and liquid Al has been studied by carrying out the tests on Nb(s)-Al(l) and Nb(s)-Al(l)-Ni(s) reaction couples isothermally reacted between 700℃ and 900℃ for different time intervals.It has been found that the interaction layer between Nb and Al contains two parts: a thin continuous layer of NbAl3 adjacent to the Nb surface and a two-phase zone constituted of NbAl3 particles dispersed in an Al matrix. Although the nature and growth of interaction layers follows the four-stage mechanism, a typical cruciform pattern does not occur in Nb(s)-Al(l) reaction couples. However, a cruciform pattern was observed in Nb(s)-Al(l)-Ni(s) reaction couples. The movement of NbAl3 particles is important to the production of cruciform pattern in the reaction couples. |
