of strength by enhancing dislocation pinning. Hence, the existence of cellular structure in grains leads to differences in the prediction of material strength by Hall-Petch relationship... additive manufacturing metal materials through the Hall-Petch formula, the grain size should be used as the basis for calculation. Key words: additive manufacturing; Hall-Petch relationship; grains......
Effect of internal pressure distribution on thickness uniformity of hydroforming Y-shaped tubePENG Jun-yang1, ZHANG Wen-da1, LIU Gang1, ZHU Shi-qiang2, YUAN Shi-jian1(1. National Key Laboratory..., however, owing to the high-friction forces acting at internal pressure in the guiding zone between the tube and die, less metal flows into the protrusion. A multistage punch was proposed to change......
