Effect of Thermomechanical Processing on Microstructures of TRIP Steel

TANG Zhengyou , DING Hua , DU Linxiu , DING Hao , ZHANG Xin

钢铁研究学报(英文版)

In order to control retained austenite, the effect of hot deformation in the intercritical region on the microstructure of hotrolled transformationinduced plasticity (TRIP) steel was studied on a Gleeble 1500 hot simulator. Compressive strains varying in amounts from 0 to 60% were imposed in the i...

Fatigue Property of Low Cost and High Strength Wheel Steel for Commercial Vehicle

WANG Ning , LI Yi , DU Linxiu , WU Di , LIU Xianghua

钢铁研究学报(英文版)

The fatigue properties of the newly developed wheel steel used for commercial vehicles were studied using pushpull axial loading fatigue tests with stress ratio R=-1. Q235B steel, which is conventionally applied to commercial vehicle wheels, was also analyzed for comparison. Although the chemical c...

Effect of WarmRolled Pearlite Microstructural Features on Austenitic Transformation

YAO Shengjie , DU Linxiu , LIU Xianghua , WANG Guodong

钢铁研究学报(英文版)

The austenite transformation characteristics for various warmrolled pearlite during rapid heating were investigated. The results indicate that the start temperature (Ts) is sensitive to the microstructural feature of pearlite, whereas the dislocation plays an important role in the transformation ra...

Development of NbVTi HotRolled High Strength Steel With Fine Ferrite and Precipitation Strengthening

YI Hailong , DU Linxiu , WANG Guodong , LIU Xianghua

钢铁研究学报(英文版)

A hotrolled steel with high yield strength of 700 MPa, good elongation of about 20% and low ductilebrittle transition temperature (DBTT) lower than -70 ℃ has been developed in laboratory. The results show that adopting finishing rolling temperature of around 800 ℃ is rational, and coiling temperat...
