Boriding of carbon steel C45 with subsequent difusion annealing
2021Boriding is a type of thermal diffusion process in which the chemical element boron diffuses in the surface layers of steel at elevated temperatures (800 to 1000°C) which, together with iron (Fe), forms iron borides that have a very high hardness (1500-2100 HV) and wear resistance, to abrasion and erosion.

Chip formation analysis during dry turning of C45 steel
STUDIES IN ENGINEERING AND EXACT SCIENCESMachining is a material removal process that creates surfaces through chip formation using a cutting tool. The morphology of the chips and the mechanisms governing their formation directly affect the quality of machined parts. This experimental study examines chip formation mechanisms in the dry turning of C45 steel under various cutting conditions ...

Characterization of surface layer obtained by boronizing of C45 steel
2019This study deals with characterization of surface layers obtained by pack boronizing C45 steel at 870 °C for 6 h. Analysis is performed to assess average thickness, change of volume share of boride phase and the surface microhardness in the layer cross section.

International Journal of Fatigue, 2016
Abstract The article presents a new hybrid method to be applied for calculations of construction steel fatigue life on the example of C45 steel (standard AISI: 1045 steel). The hybrid method involves an assumption that cyclic properties of steel in the range of low cycle fatigue (LCF) are defined in strain based approach by strain diagram of Manson ...

Dependence between Workpiece Material Hardness and Face Lapping Results of Steel C45
Solid State Phenomena, 2015The high demands required today by manufacturing engineers for machine parts and tools necessitate very precise machining. The finishing processes are an important perspective to be considered today for meeting the goals like parallelism, tolerances, flatness, and smooth surface.

Research on morphology of boride layers obtained on C45 steel
2016This study focuses on morphology of borides formed on C45 steel. Pack boronizing is carried out at a temperature range of 870 – 970 °C in durations of 4 to 8 h. Through use of linear method, average thicknesses of boride layers as well as volume share of boride phase concerning cross section of the layer are determined.
