Three body type abrasive wear characteristics of multi-component white cast irons
Published in Wear
Abrasive wear can occur on tooth and suspension parts such as construction machinery power shovels and bulldozers. In order to reach high safety and low cost, it is important to develop wear resistant material and estimate of life service during abrasion. The amount of alloy element dissolved in the matrix is changed by the type of carbide and m...
VOLUMETRIC CHANGES AT HEATING IN STEEL 60Si2CrV SUBJECTED TO Q&P TREATMENT
Published in Izvestiya. Ferrous Metallurgy
Представлены результаты исследования фазово-структурных превращений и объемных изменений, протекающих при нагреве в рессорной высококремнистой стали 60С2ХФА, подвергнутой Q-n-P-обработке. Исследовали сталь, содержащую 0,53 % С; 1,46 % Si; 0,44 % Mn; 0,95 % Cr; 0,10 % V; 0,016 % S; 0,013 % P. Образцы стали подвергли Q-n-P-обработке по режимам: ауст...
Effects of stress relief tempering on microstructure and tensile/impact behavior of quenched and partitioned commercial ...
Published in Materials Science and Engineering A
The primary aim of the present study was to investigate the impacts of tempering (at 200–300 °C) on microstructure and mechanical properties of commercial spring steel of 60Si2CrV grade under “Quenching and Partitioning” heat treatment. Three different heat treatment routes were applied: (a) oil quenching and tempering at 300 °C (Q-T), (b) bath que...

Optimal Parameters of Q&P Heat Treatment for High-Si Steels Found by Modeling Based on “Constrained Paraequilibrium” Con...
Published in Fracture at all Scales
The article is dedicated to designing the regime of Q&P (Quenching and Partitioning) heat treatment for middle-carbon high-silicon steels 60Si2CrVA and 55Si3Mn2CrVMoNbA in order to improve their mechanical properties. The temperature of suspense of quenching cooling during Q&P treatment was calculated by modeling based on the concept of “Constraine...
