Effect of heating temperatures on AlSi coating microstructure and fracture during hot-tensile tests

In this article, the fracture behavior of different AlSi coating micro-structures is investigated. By changing heating temperature, are obtained, due to varying diffusivity iron. To study micro-structures, uniaxial tensile tests conducted at 700 °C. The hot test involves as-coated press hardening steel in a furnace temperatures 750, 920 and 1000 °C for 6 minutes dwell time, after which sample cooled deformation stage stage, samples uniaxially deformed fixed 20% macroscopic strain followed by cooling room temperature. After test, micro-structure pattern inspected under microscope. For heated 750 °C, observed; however, no observed during micro-structure, becomes sufficiently ductile withstand same fractures 600
