Coarsening of M23C6 Precipitates in an Fe-Cr-C Ternary Alloy

ZHU Na-qiong , LU Li , HE Yan-lin , LI Lin , LU Xiao-gang

钢铁研究学报(英文版)

Coarsening of M23C6 precipitates in an Fe-12.4Cr-0.13C ternary alloy has been investigated ageing at 780 ℃ up to 200 h. Evolution of M23C6 carbides at different ageing times was determined experimentally using transmission electron microscopy. Particle size distribution was obtained with different m...

Design of TRIP Steel With High Welding and Galvanizing Performance in Light of Thermodynamics and Kinetics

LI Lin , DE COOMAN B C , LIU Rendong , VLEUGELS J , ZHANG Mei , SHI Wen

钢铁研究学报(英文版)

A new type of transformation induced plasticity (TRIP) steel with not only high strength and high ductility but also superior welding and galvanizing properties was designed and developed recently. Low carbon and low silicon content were preliminarily selected with the aim of meeting the requirement...

Influences of Black Carbon Addition on Mechanical Performance of Low-Carbon MgO-C Composite

LI Lin , TANG Guangsheng , HE Zhiyong , et al

钢铁研究学报(英文版)

Carbon black-phenolic resin composite binders with various amounts of nanometer carbon black were prepared through adding KH-550 coupling agent and high-speed mixer. The effects of nanometer carbon black amount added on viscosity of the composite binders were studied. Low carbon MgO-C specimens were...

Tensile Properties of TWIP Steel at High Strain Rate

XIONG Ronggang , FU Renyu , SU Yu , LI Qian , WEI Xicheng , LI Lin

钢铁研究学报(英文版)

Tensile tests of TWIP steels of two compositions are performed in the strain rate range of 10-5-103 s-1. Results indicate that steel 1# does not exhibit TWIP effect but deformationinduced martensitic transformation appears only. There exists TWIP effect in steel 3#. Tensile properties at room tempe...

Effect of Overaging on Solute Distributions and Bake Hardening Phenomenon in Bake Hardening Steels

WANG Hua , SHI Wen , HE Yan-lin , LU Xiao-gang , LI Lin

钢铁研究学报(英文版)

Specimens of two different kinds of bake hardening steels (BH-Mn and BH-P) were prepared and treated with different annealing processes (water quenching and overaging). A novel technique of three dimensional atom probe was used to investigate solute distributions in these steels. The results indicat...

Weldability of Low Carbon Transformation Induced Plasticity Steel

ZHANG Mei , LI Lin , FU Renyu , ZHANG Jicheng , WAN Zi

钢铁研究学报(英文版)

Transformation induced plasticity (TRIP) steel exhibited high or rather high carbon equivalent (CE) because of its chemical composition, which was a particularly detrimental factor affecting weldability of steels. Thus the weldability of a TRIP steel (grade 600) containing (in mass percent, %) 011C...

Thermal Stability of Retained Austenite in TRIP Steel After Different Treatments

SHI Wen , LI Lin , Bruno C De Cooman , Patrick Wollants , YANG Chunxia

钢铁研究学报(英文版)

Thermal decomposition of retained austenite in TRIP steel was investigated by means of differential scanning calorimetry (DSC). The decomposition curve was abnormal, and the decomposition temperature and the activation energy were measured by the Kissinger method, which were all higher than those in...
