High strength bainitic steel plates were produced by using thermo-mechanical control and
accelerated cooling process to optimize the mechanical properties. The strength increased …

Seismic anti-seismic rebar, as materials for supporting structures in large buildings, need to
have excellent mechanical properties. By increasing the Nb content and controlling the …

The recent increased severity in service conditions, such as frequent earthquakes, have
further promoted the development of steel production technologies for many types of …

Two low carbon steel grades were used in the present investigation. One of them was
microalloyed with Ti, V, and Nb. Both steel grades were subjected to a controlled hot forging …

The present work aims to study the evaluation of the microstructure, tensile properties,
hardness, corrosion behaviour of the various grades of rebars. The microstructures of all …

Three cooling processes (direct air cooling, water cooling to 1023 K and 873 K (750° C and
600° C) followed by air cooling) after hot rolling are designed to develop VN-alloyed 600 …

Laboratory experiments of a high-strength Ti-Nb microalloyed steel were conducted with two
cooling modes, ie, a large (35° C s− 1) cooling rate in the initial stage followed by slow (8.5° …

After cooling in the hot rolling process, the metallographic structure of microalloyed dual-
phase steel is nonuniform along the rolling direction, while the thickness fluctuation of …

Nb+ V 和V 微合金非调质钢常应用于汽车的结构件与保安件, 疲劳断裂是其主要的失效形式,
因此有必要对其疲劳断裂行为进行深入研究. 利用LEICA Q550 IW 型光学显微镜, AG-25TA …

The corrosion performance of rebar cooled by a chemical reagent (FM) was compared with
water-cooled and air-cooled rebar. The influence of compositions and structure of the three …
