The Friction-Assisted Lateral Extrusion Process (FALEP) is a severe plastic deformation (SPD) technique for producing metal sheets from bulk or powder in one single step at room temperature. In the present work, aluminum Al-1050 was deformed by FALEP. Then, its microstructure examined EBSD; crystallographic texture X-ray; material strength, ductility, and Lankford parameter tensile testing; latter also polycrystal plasticity simulations. It shown that highly refined, with grain size reduced...
Fe‐based heat‐resistant A286 superalloy is an age‐hardened austenitic stainless steel. Age‐hardening greatly affected by TiC particles and η ‐Ni 3 Ti phases. Herein, the evolution of (hcp‐Ni Ti) precipitations investigated in six different alloys with simultaneous variations C contents, such as 0.00C–2.38Ti, 0.02C–2.46Ti, 0.04C–2.54Ti, 0.05C–2.58Ti, 0.06C–2.62Ti, 0.08C–2.69Ti wt%. During microstructure from solutioning state (900 °C for 2 h) to aging (720 °Cfor 16 h), nodular/needle‐like...
Nowadays, electric traction is applied in highspeed trains, and the effects of crosswind increase instability pantograph turbulence, so higher requirements are put forward for good contact between catenary. A new type working height 2800 mm a running speed 400 km/h was taken as object this study. Based on three-dimensional, steady, incompressible N-S equation k- ω SST (Shear Stress Transport) turbulence model, variation aerodynamic force lift with different yaw angle were analyzed. The...
Precipitation-hardening is achieved in an Fe-Ni-based A286 austenitic superalloy by means of aging process. During the process gamma prime phases (γ’), eta (η) and TiC nucleate matrix this alloy. In research, behavior η-phases’ precipitation, dissolution transformation into γ’-phase γ-matrix, their consequent effect on high temperature hardness testing compression investigated The phase nucleation examined after at 710 ºC for different lengths time (1h, 2h, 4h 8h). Scanning electron...
