Abstract

This experiment devised a set of cold-hot partitioning molds for preparing U-shaped components made of 22MnB5 with variable strength. Employing a hot stamping process, the molds were set at temperatures of 400℃, 450℃, and 500℃ respectively. Samples were taken from the soft and hard regions of the fabricated components, and the transition zone length was determined through hardness testing. The mechanical properties of the hard and soft regions were assessed via uniaxial tensile tests, yielding the corresponding engineering stress-strain curves, tensile strength, and elongation at fracture. Microstructural observations were conducted using SEM to summarize the influence of mold temperatures on the mechanical properties of the produced components.
