tensile ductility 中文意思是什麼
tensile ductility
解釋
拉伸塑性-
From an examination of the tensile behavior of cz ly12 alloys under different temperature and strain rate, two kinds of deformation and intergranular fracture behaviors were observed that were opposite to the characteristic strain rate range in fine - grained superplasticity. the mechanisms are described as follows. the high ductility achieved at high strain rate is generally attributed to the dominant role of gbs accommodating mechanisms, which is considered as dislocation creep within grains controlled by subgrains
研究選用自然時效淬火態的ly12鋁合金，進行了一系列不同溫度和應變速率下的單軸拉伸試驗， 480下，觀察到與傳統細晶超塑性特徵區間相反的行為：較高應變速率下，動態再結晶使晶粒細化，促進了晶界滑移，亞晶界控制的晶內位錯蠕變是晶界滑移的主要協調機制。 -
The results show that, with the quenching temperature ( 270 ~ 380 ) increasing, the carbon content and percentage content of retained austenite increase first and then decrease, which are up to a maximum value at 360 ; the tensile strength of adi decreases ; the elongation and impact ductility of adi increase first and then decrease, which are up to a maximum value at 360 ; but the hardness of adi decreases first and then increases, which is up to a minimum value at 360
結果表明，在試驗溫度范圍內（ 270 ~ 380 ） ，試樣中殘余奧氏體的含碳量及其含量隨著等溫淬火溫度的升高先增大后減小，均在360等溫淬火時出現最大值；抗拉強度隨著等溫淬火溫度的升高而逐漸降低；伸長率和沖擊韌度隨著等溫淬火溫度的升高先增大后減小，在360等溫淬火時出現最大值；硬度則隨著等溫淬火溫度的升高先減小后增大，當360溫淬火時硬度最低。 -
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。 -
There are reverse relationships between room - temperature fracture toughness and tensile ductility with the change of grain sizes in two - phase tial - based alloys. but the essence of the reverse relationships is not clear. in order to solve these problems, it is vital to investigate room - temperature fracture mechanisms of tial - based alloys
另外隨著晶粒尺寸的增加tial基合金的室溫塑性與斷裂韌性呈現相反依賴關系，這種相反依賴關系的本質至今還不是很清楚，要解決這些問題，也必須搞清楚其斷裂機理。 -
