| 英文摘要 | The effects of P and B on the matrix strength and precipitations of gamma ' and gamma '' phases in the grain interior were re-recognized in this study. The combination addition of P and B markedly accelerated the precipitations of gamma ' and gamma '' phases and strengthened the matrix of IN718 alloy when air-cooled from high temperature, while made no difference when water-quenched from high temperature. The effect of single addition of P on the precipitations of gamma '' and gamma ' phases was the same with that of the combination addition of P and B, while the single addition of B had no effect on the precipitations of the two phases. Therefore, it was P rather than B which accelerated the precipitations of gamma ' and gamma '' phases. P could take part in the precipitations of gamma ' and gamma '' phases, which was revealed by electrochemical extraction and quantitative analysis of chemical composition. It also revealed that P atoms were dissolved in the gamma matrix to a relatively high degree at the temperature that gamma ' and gamma '' phases began to precipitate, and consequently the precipitations of gamma ' and gamma '' phases were accelerated. The first-principle calculation indicated that P decreased the formation enthalpies of gamma ' and gamma '' phases when it occupied the Ni lattice sites in the two phases, which explained the effect of P on the gamma ' and gamma '' phases. |
