Wear, 1987
Abstract The erosion behavior of AISI 4140 steel under various heat treatment conditions was investigated. A variety of microstructures, such as the primary and tempered martensites, varying proportions of martensite and bainite, cementite spheroids embedded in a ferrite matrix and ferrite and pearlite were obtained.

Tribocorrosion behavior of boronized AISI 4140 steel
Surface and Coatings Technology, 2018Abstract In this study, AISI 4140 steel was boronized using powder-pack‑boronizing process, seeking to produce a monophasic iron boride (Fe2B) layer. The microstructural and chemical characteristics were evaluated by Scanning Electron Microscopy (SEM), Energy Dispersive Spectroscopy (EDS), respectively and Grazing incidence X-ray diffraction (GIXRD).

Erosion of heat-treated AISI 4140 steel
Materials Science and Engineering: A, 1993Solid-particle erosion was studied on AISI 4140 steel heat treated to have a Vickers hardness (Hv) of 288–650 kg mm−2. The experiments were conducted in vacuum with 143 μm Al2O3 abrasive impacting at 50–100 m s−1 at an angle of 30° or 90°. Erosion rates were nearly independent of hardness for Hv ⩽ 365 kg mm−2, but increased with hardness for Hv > 365 ...

Hydrogen diffusion through copper-plated AISI 4140 steels
Corrosion Science, 1992Abstract In order to control the hydrogen embrittlement problems of high strength steels, electrochemical hydrogen permeation experiments were performed on copper-plated AISI 4140 steels to evaluate the beneficial effect of an impermeable coating. Copper plating led to a lower hydrogen permeation rate and effective diffusivity due to its low hydrogen
