Investigation of Wear Mechanism in Quenched and Tempered Medium Carbon-High Chromium Martensitic Steel Using Dry Sand/Rubber Wheel
The aim of the present study was to investigate the effect of quenching and tempering temperatures on the microstructure, mechanical properties and the wear characteristics of medium carbon-high chromium wear resistant steel. In addition, the dominant wear mechanisms were studied. For this purpose, austenitizing and tempering temperatures were selected in the ranges of 900- 1000 °C and 300- 500...

متن کاملCreep Fracture in Tempered Martensitic Steels
Creep strength enhanced ferritic (CSEF) steels which contain 9 to 12%Cr have become the steels of choice in many industrial high energy systems. The typical compositions of alloy types P91, P92 and E911 are compared with 12CrMoV in Table 1. These steels are selected for use in applications where high temperature creep can occur because of a favorable balance between cost and properties [1,2]. T...
متن کاملPrecipitate design for creep strengthening of 9% Cr tempered martensitic steel for ultra-supercritical power plants.
It is crucial for the carbon concentration of 9% Cr steel to be reduced to a very low level, so as to promote the formation of MX nitrides rich in vanadium as very fine and thermally stable particles to enable prolonged periods of exposure at elevated temperatures and also to eliminate Cr-rich carbides M23C6. Sub-boundary hardening, which is inversely proportional to the width of laths and bloc...
متن کاملData related to dislocation density-based constitutive modeling of the tensile behavior of lath martensitic press hardening steel
The data presented in this article are related to the research article entitled "On the plasticity mechanisms of lath martensitic steel" (Jo et al., 2017) [1]. The strain hardening behavior during tensile deformation of a lath martensitic press hardening steel was described using a dislocation density-based constitutive model. The Kubin-Estrin model was used to describe strain hardening of the ...
