| 1 | 采用延性损伤模型和数值方法预测Ni-Cr基合金在温成形条件下的断裂极限显示文摘为了确定IN625合金的安全成形和断裂极限,在300和673 K下分别进行拉伸成形和深拉延成形实验。将实验获得的基于应力的断裂成形极限图(FFLD)转变为基于应力的σ-FFLD和有效塑性应变(EPS)跟三轴度(η)的关系曲线,以消除断裂极限对应变的过度依赖。为了预测断裂极限,校准7种不同的损伤模型。结果显示,Oh模型对断裂轨迹的预测能力最好,绝对误差最小。虽然实验得到的断裂极限仅用于数值分析,但没有一个损伤模型预测整个应力三轴度范围(0.33<η<0.66)的断裂应变。在不同的温度和润滑条件下深拉延成形圆柱杯,深拉延工艺窗口有助于确定起皱、安全和断裂区域。在润滑条件下,673 K时达到最大的拉延比2。利用Hill 1948各向异性屈服函数对拉伸成形和深拉延成形过程的数值预测结果均在可接受的误差范围内。 | Ayush MORCHHALE Anand BADRISH Nitin KOTKUNDE Swadesh Kumar SINGH Navneet KHANNA Ambuj SAXENA Chetan NIKHARE | 2021 | Transactions of Nonferrous Metals Society of China2021，31，8： | 3 |
| 2 | 材料模型对高温Ti-6Al-4V合金理论成形极限图预测的影响(英文)显示文摘成形极限图是一种用来描述使板材不发生局部颈缩所需最大主应变的重要图形。它是一种预测板材变形过程中变形极限的方便、有效的工具。本研究中,在400°C和不同样品宽度的条件,通过Nakazima实验得到了Ti-6Al-4V合金的成形极限图。此外,为了使用成形极限图对材料参数进行理论预测,提出了不同的各向异性屈服准则(Barlat 1989,Barlat 1996,Hill 1993)和不同的硬化模型(Hollomon幂定律、Johnson-Cook(JC)模型、改进的Zerilli-Armstrong(m-ZA)和Arrhenius(m-Arr)模型)。结合所提出的屈服准则和本构模型,通过Marciniak和Kuczynski(M-K)理论确定了Ti-6Al-4V合金的成形极限图。结果表明:屈服模型对材料成形极限图的影响大于本构模型的影响。然而,材料的厚度缺陷系数(f_0)与其硬化模型密切相关。Hill(1993)屈服准则最适合于成形极限图右边区域的预测,而Barlat(1989)屈服准最适合于成形极限图左边区域的预测。由于所得到的混合理论成形极限图兼具Barlat(1989)和Hill(1993)屈服模型和m-Arr硬化模型的优点,因此,它与实验得到的成形极限图吻合很好。 | Nitin KOTKUNDE Sashank SRINIVASAN Geetha KRISHNA Amit Kumar GUPTA Swadesh Kumar SINGH | 2016 | Transactions of Nonferrous Metals Society of China2016，26，3： | 2 |
| 3 | Metallurgical Studies of Austenitic Stainless Steel 304 under Warm Deep Drawing显示文摘Austenitic stainless steel 304 was deep drawn with different blank diameters under warm conditions using20 thydraulic press.A number of deep drawing experiments both at room temperature and at 150℃ were conducted to study the metallography.Also,tensile test experiments were conducted on a universal testing machine up to 700 ℃and the broken specimens were used to study the fractography of the material using scanning electron microscopy in various regions.The microstructure changes were observed at limiting draw ratio(LDR)when the cup is drawn at different temperatures.In austenitic stainless steel,martensite formation takes place that is not only affected by temperature,but also influenced by the rate at which the material is deformed.In austenitic stainless steel 304,dynamic strain regime appears above 300℃ and it decreases the formability of material due to brittle fracture as studied in its fractography.From the metallographic studies,the maximum LDR of the material is observed at 150 ℃ before dynamic strain regime.It is also observed that at 150 ℃,grains are coarse in the drawn cups at LDR. | Jayahari Lade Balu Naik Banoth Amit Kumar Gupta Swadesh Kumar Singh | 2014 | Journal of Iron and Steel Research(International)2014，21，12： | 2 |
