AISI 1050 steel samples are borided for 2, 4 and 6 h at 850, 900 and 950°C by the powder-pack boriding method using Ekabor-II boriding powder. After the powder-pack boriding, about 25.4 – 118.9 μm thick FeB/Fe2B boride layers are obtained on the surfaces of the samples. The boride layers have a typical tooth morphology and their hardness is 1071 – 1460 HV0.1. The growth rate constants for the boriding temperatures of 850, 900 and 950°C for the AISI 1050 steel are determined to be 1.522 × 10 –12, 2.964 × 10 –13 and 6.354 ×10 –12 m2 · sec –1, respectively. The boron diffusion activation energy in the AISI 1050 steel is 162.93 kJ · mol –1. © Springer Science+Business Media, LLC, part of Springer Nature 2024.EnglishActivation energyBoridesBoridingDiffusionIronKineticsMicrostructureMorphologyRate constants950° CAISI 1050 steelBoride layersBoron diffusionsDiffusion activation energyDiffusion kineticsGrowth rate constantIron boridePack boridingSteel samplesGrowth kineticsArticle10.1007/s11041-024-01001-9
