(PDF) Comparative study of the corrosion behaviour of

In this study, the corrosion behaviour of plasma nitrocarburised AISI 4140 steel before and after post-oxi- dation was investigated. Plasma nitrocarburising was carried out at 530 ° C, 570 ° C (PDF) Feasibility Exploration of Superalloys for AISI 4140 Laser-aided direct metal deposition (DMD) was used to form a AISI 4340 steel coating on an AISI 4140 steel substrate. Stress in the coating was relieved before mechanical testing.

Evaluation of AISI 4140 Steel Repair Without Post-Weld Heat Treatment more by Cicero Moura The present work evaluates the two-layer technique on the heat affected zone (HAZ) of AISI 4140 steel welded with different heat input levels between the first and second layer. Construction of metal transfer modes maps for an ER4130 1. Introduction. Chromium-molybdenum steels such as AISI-SAE 4130, 4140 and 4150 are heat-treatable low-alloy steels (HTLA) whose microstructure and mechanical properties are produced by quenching and tempering (Q&T) [1, 2].These alloys are mainly used in heavy machinery (shafts, gears, dies) [], the automotive and aerospace industry [4-6] and large construction projects. Effect of nonmetallic inclusion and banding on the success In conclusion, the two-layer temper bead welding technique can be used satisfactorily in welding without PWHT for AISI 4140 steel. However, a close evaluation of the base metal characteristics is

Evaluation of double-layer weld deposition technique on

Jul 10, 2019 · The present work evaluates the mechanical and metallurgical behavior of ASTM A182 F22 steel heat-affected zone (HAZ) through the double-layer weld deposition technique, with different welding energies between the first and second layers. This methodology leads to the reduction of hardness levels in the HAZ and can exempt the need for post-weld heat treatment on low-alloy steel after buttering Investigation of the Repair Welding Technology Using Ni [3] V.
