High-strength steel (AHSS) for lightweight, strong parts [1.7].
Mention high-temperature forming (heating) to improve ductility [1.4]. bendability
Discuss methods like annealing to refine microstructures (e.g., fine High-strength steel (AHSS) for lightweight, strong parts [1
In many metals, bending failure begins with surface microcracks, often caused by rough surfaces [1.9]. High-strength steel (AHSS) for lightweight
Explain the tension on the outer (convex) surface and compression on the inner (concave) surface [1.1].
Discuss how grain structure, inclusions, and surface roughness (e.g., from MDPI ) influence crack initiation [1.7, 1.9].
The presence of non-metallic inclusions in steel can drastically reduce its bendability [1.7].
