hot ductility 中文意思是什麼
hot ductility
解釋
熱態可延展性-
Based on these experiments, it may be claimed that there is segregation of sn to grain boundaries in 0. 15 % c steel during cooling from a high solution treatment temperature. this segregation reduces grain boundary cohesion, which results in low hot ductility and intergranular fracture
通過試驗和計算得出: sn在0 . 1swt . % c鋼中發生非平衡晶界偏聚的臨界時間為1245左右，臨界冷卻速率大約為8 / s ，與試驗結果基本一致。 -
In the third ductility region, the reduction in area of the sn - undoped steel is larger than that of the sn - doped steel. this means that the hot ductility of the sn - undoped steel is better than that of the sn - doped steel
在第類脆性溫度區內，不含sn鋼的斷面收縮率大於含sn鋼的斷面收縮率，即不含sn鋼的熱塑性要比含sn鋼的熱塑性好。 -
Based on the hot tensile test results, there exists a cooling rate at which a minimum reduction in area occurs and the hot ductility of the sn - doped steel is worse than that of the sn - undoped steel. when the cooling rate is lower or higher than 10 / s, the hot ductility is increased
連續冷卻到750 800范圍內拉伸時，存在一個冷卻速率（ 10 s ） ，以這個冷卻速率進行冷卻，試樣的斷面收縮率最小，熱塑性最差；當冷卻速率大於或者小於這個冷卻速率時，試樣的斷面收縮率均會增大，熱塑性增強。 -
The segregation mechanism of tramp element sn during continuous cooling and isothermal aging and its influence on the hot ductility of low carbon steel are discussed and the brittleness during continuous casting of the sn - doped low carbon steel is forecasted. at a strain rate of 10 - 2s - 1 and a cooling rate of 10 / s, there exists a third ductility trough for both steels at 750
在應變速率和冷卻速率分別為10 ~ （ - 2 ） s和10 s的條件下進行熱模擬拉伸時，兩種試驗鋼均在750時出現由先共析鐵素體沿奧氏體晶界呈薄膜網狀析出所引起的第類脆性谷底。 -
Addition of sn deteriorates the hot ductility, deepens the ductility trough, and shifts the ductility region to higher temperatures
Sn的存在惡化了鋼的熱塑性，導致第類塑性谷底加深，塑性凹槽上限向高溫擴展。 -
The results of auger electron spectroscopy indicate that sn segregation occurs during continuous cooling and the degrees of segregation are different for different cooling rates. at a cooling rate of 10 / s, the maximum sn segregation and the worst hot ductility occur
俄歇能譜表明， sn不僅在連續冷卻過程中發生了晶界偏聚，而且sn的晶界偏聚量隨著連續冷卻速率的變化而變化。
