The main results were summarized as follows: 1 With the increase of cooling rate, full recrystallization during cooling became difficult to take place and the decrease in dislocation density became slow so that dislocation density in austenite remains higher before phase transformation occurred. 2 Compared with undeformed samples, the CCT diagram under deform conditions has a similar shape, but its position shifts leftwards.

計算結果表明：1隨著冷卻速率增大亚洲淫乱性图，低碳鋼熱變形后的冷卻過程中再結晶變得越來越困難大型日韩精品网站视频在线观看免费，位錯密度的下降變慢，導致在相變前奧氏體中保留著較大的變形存儲能www.亚洲com.第四页；2奧氏體在經歷熱變形后的CCT曲線與未變形條件相比亚洲女生被插下体免费看网站，明顯向左上方偏移免费久久性爱视频。

Deformation greatly promoted carbonitride isothermal precipitation and made C-curve shift leftwards. The position and shape of C-curve depended on the content of Nb and N to a great extent, C-curve shifted leftwards a little when N content increased and its nose temperature was raised with Nb content increased. 3 when cooling rate increased, start temperature and finish temperature of continuous cooling precipitation decreased, full precipitation became difficult to take place, the volume fraction of carbonitride precipitation decreased, molar fraction of Nb and C dissolved in austenite increased, and the precipitation grain was further refined. Deformation shorten precipitation start time during continuous cooling, raised precipitation start temperature, accelerated precipitation kinetics of carbonitrides.
