    摘要:

    本文研究了不同形變熱處理工藝參數(shù)對(duì)冷軋態(tài)鎳基高溫合金中晶界特征分布演變的影響。結(jié)果表明，在退火處理過(guò)程中，生長(zhǎng)事故模型是靜態(tài)再結(jié)晶(SRX)晶粒中新Σ3晶界形成的主要機(jī)制。隨著退火時(shí)間和退火溫度的增加，晶界遷移時(shí)間延長(zhǎng)，晶界遷移速度加快，從而增加了生長(zhǎng)事故的發(fā)生頻率，促進(jìn)了Σ3晶界的形成。此外，隨著應(yīng)變的增加，Σ3晶界的比例先減小后增大。在冷軋變形量為0.1和0.7時(shí)，Σ3晶界的比例均可達(dá)到60%左右，這與大晶粒團(tuán)簇的形成密切相關(guān)。此外，本文還詳細(xì)分析了不同工藝參數(shù)下，Σ1晶界、共格Σ3晶界、非共格Σ3晶界、Σ9晶界、Σ27晶界和隨機(jī)晶界的演變規(guī)律。

    Abstract:

    The influence of thermal-mechanical processing (TMP) parameters on the grain boundary character distribution evolution in a cold-rolled Ni-based superalloy was studied. During annealing treatment, growth accident model was considered to be the main mechanism for the formation of new Σ3 boundaries in the SRX grains. With the increasing annealing time and temperature, there was more time for grain boundary migration and the grain boundary migration was faster at the higher annealing temperature, which could stimulate the formation of Σ3 boundaries by increasing the frequency of growth accidents. In addition, the fraction of Σ3 boundaries decreased firstly with the increasing strain, and then increased again. At the strains of 0.1 and 0.7, the fractions of Σ3 boundaries reached around 60%, which was related to the well development of large grain-clusters. Besides that, the evolution of Σ1 boundaries, coherent Σ3 boundaries, incoherent Σ3 boundaries, Σ9 boundaries, Σ27 boundaries, and random boundaries were also analyzed in detail.
