Diffusion boronising of hot work tool steel
Original language description
Abstract H11 hot work tool steel was boronized at various processing parameters, austenitized, quenched and tempered to a core hardness of 47 - 48 HRC. Microstructure, phase constitution and microhardness of boronized layers were investigated. Effect ofboronized region on the bulk properties was determined by the Charpy impact test. Structure of boronized regions is formed by the compound layers and diffusion inter-layer. They are formed with diffusion regions and compound region, which consisted of only Fe2B-phase but in the case of longer processing time also of the FeB - phase. Microhardness of boronized layers exceeded considerably 2000 HV0.1. However, boronizing led to a substantial lowering of the Charpy impact toughness of the material.
