Research on High-Temperature Damage Behavior of Super Martensitic Stainless Steel 04Cr13Ni5Mo Based on Finite Element Simulation

Tonghui Sun, Jihong Tian, Huiqin Chen, Bo Zhang et autres

04Cr13Ni5Mo martensitic stainless steel is extremely sensitive to forging temperature and is prone to generating extremely large cracks, which leads to the failure of forging. Therefore, high-temperature tensile tests were performed on 04Cr13Ni5Mo martensitic stainless steel using a Gleeble-1500D thermo-mechanical simulator to …

Numerical analysis of splicing temperature difference in welded steel box girder segments

Weiqing Zhu, Yi Xiao, Minghui Li, Gang Long et autres

Splicing quality issues are commonly observed in field-welded steel box girder segments exposed to ambient environmental temperatures. To investigate the effect of splicing temperature difference (STD) and improve construction quality, finite-element models were developed to simulate the welding–splicing process of these segments. …

Molecular Dynamics Simulations on the Deformation Behaviors and Mechanical Properties of the γ/γ′ Superalloy with Different Phase Volume Fractions

Xinmao Qin, Wanjun Yan, Yilong Liang, Fei Li

Based on molecular dynamics simulation, we conducted a comprehensive study on the tensile behaviors and properties of the γ(Ni)/γ′(Ni3Al) superalloy with varying γ′(Ni3Al) phase volume fractions (Vγ′) under high-temperature, high-strain-rate service environments. Our investigation revealed that the tensile behavior of the superalloy …

Influence of Ultrasonic Surface Rolling Process on the Correlation Between Fatigue Strength and Crack Initiation Radius Ratio in Notched Inconel 718 Specimens

Fei Li, Yilong Liang, Xinmao Qin, Guigui Peng et autres

ABSTRACT This study examines the effect of ultrasonic rolling on the high‐cycle fatigue strength of notched Inconel 718 superalloy. Fatigue strength and crack initiation location are analyzed from microstructural, stress‐state, and fatigue‐strength perspectives. Results show fatigue strength varies significantly with crack initiation …
