    摘要:

    研究γ''相回溶過程并模擬Al+Ti含量以及Ti/Al比對γ''相后續(xù)冷卻析出的影響。γ''相的冷卻析出與γ''相回溶及回溶后Al、Ti元素的擴散動力學過程有關。保溫時間延長與固溶溫度升高使γ''冷卻析出相尺寸減?。徊煌渌傧?γ''析出相尺寸、形狀與分布不同。TTT與CCT曲線中,隨著Al、Ti含量的增加,不同速率下的γ''析出相溫度升高且相對應的析出時間提前。水冷乃至冷卻速率達至1000 ℃/min時,無法抑制γ''相冷卻析出。Ti/Al比的變化對γ''相的析出基本無影響。

    Abstract:

    The influence of the dissolution process of γ'' phase on the subsequent precipitating process of γ'' phase was investigated and the effect of Al+Ti contents and Ti/Al ratios to γ'' precipitate was also simulated. The precipitation of γ'' phase are influenced by the dissolution of γ'' phase and the diffusion of Al and Ti content. The size of γ'' precipitate decreases with the increase of solution time and temperature. The precipitation of γ'' phase exhibits various sizes, shapes and distributions under the water cooling condition. It can be shown in TTT and CCT curves that the precipitating temperature increases and the precipitating time decreases under various cooling rates with changes in Al+Ti contents. The precipitation of γ'' phase can not inhibited under the water cooling condition and even when the cooling rate is 1000 ℃/min. Meanwhile, no obvious influence is observed on the precipitation process of γ'' phase with the various Ti/Al ratios.
