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).

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.

Corrosion Behaviour of Electron Beam Welded AISI 304 and AISI 4140
Advanced Materials Research, 2011In the present work hot corrosion studies were carried out on electron beam welded AISI 304 and AISI 4140 dissimilar weldment in molten salt (K2SO4-60% NaCl) environment at 800 °C for 50 cycles. The weight gain follows parabolic law in all the cases. It is observed that the scale formation was maximum on 4140 side as compared on 304 side.

Wear behaviour of the AISI 4140 steel specimens with various surface conditions was tested against the DLC-coated boronized disc of AISI 4140 steel. Specific wear rate and coefficient of friction (COF) of the as-boronized (AB) pins at 100 and 150 N loads were substantially lower than the boronized–polished (B-P) pins.

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 ...

Alloy Digest, 1988
Abstract AISI 4140 is a through-hardening chromium-molybdenum medium carbon steel. It is not subject to temper embrittlement. It is recommended for heavy duty service. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness.
