EFFECTS OF SHOT PEENING ON HARDNESS OF 18CRNIMO7-6 STEEL BASED ON FINITE ELEMENT ANALYSIS

open access: yesJixie qiangdu, 2022
So far, most of the numerical studies on shot peening are limited in the effects of shot peening parameters on the residual stress and surface morphology. There is still lack of numerical research on shot peening parameters on the hardness.

Gradient microstructure and microhardness in a nitrided 18CrNiMo7-6 gear steel [PDF]

open access: yesIOP Conference Series: Materials Science and Engineering, 2017
A commercial gear steel (18CrNiMo7-6) containing a tempered martensite structure was nitrided using a pressurized gas nitriding process under a pressure of 5 atm at 530 °C for 5 hours. The mechanical properties and microstructure of the nitrided sample were characterized by Vickers hardness measurements, X-ray diffraction, and backscatter electron ...

Investigation on Failure Parameters of J-C Damage Model of 18CrNiMo7-6 Alloy Steel [PDF]

open access: yesZhengzhou Daxue xuebao. Gongxue ban, 2023
In this study, three series of mechanical tests were carried out on 18CrNiMo7-6 alloy steel materials to determine the damage parameters of the Johnson-Cook (J-C) damage model, which could be widely used in numerical simulations such as high-speed impact

The Synchrotron Radiation for Steel Research

open access: yesAdvances in Materials Science and Engineering, Volume 2016, Issue 1, 2016., 2016
The synchrotron X‐ray radiation is a great tool in materials characterization with several advantageous features. The high intensity allows clear interaction signals and high energy of X‐ray yields higher sampling volume. The samples do not need extra preparation and the microstructure is therefore not affected. With the tunability of the X‐ray energy,

Corrosion of MgO-C with Magnesium Aluminate Spinel Addition in A Steel Casting Simulator

open access: yesCeramics, 2020
For more than 20 years, the sidewalls and bottom of steel ladles have been lined with carbon-bonded magnesia (MgO-C) and magnesia-alumina bricks (MAC). The alumina raw materials react with magnesia forming a spinel, which decreases open porosity and slag

The Influence of the Chemical Composition of Steel on the Limitation of Austenite Grain Growth in the High-Temperature, Low-Pressure Carburizing Process

open access: yesCrystals
High-temperature low-pressure carburizing significantly reduces the time required to produce carburized layers. However, its application promotes austenite grain growth and, consequently, the formation of coarse acicular martensite.
