    Evaluation of Austenite Grains Growth in High Nb and Low

    In this research, the behavior of austenite grain growth at a high niobium low carbon (High Nb low C) and low Nb high C HSLA steel was evaluated, and the result was compared with other investigation. The results found that the austenite grain growth at high Nb high C steel was slower than the growth at a low Nb low C steel.[plate]Change of tensile behavior of a high strength low alloy [steel]The steel under investigation with the composition as represented in Table 1 was molten in a vacuum induction furnace. The as forged blocks with the size of 80 mm × 70 mm × 60 mm were hot rolled to 7 mm thick plates in the process as shown in Table 2 after soaking at 1150 °C for 2 h. The samples for the tensile test to be carried out were cut from the plate perpendicular to the rolling [plate]Fatigue properties of laser and hybrid laser TIG welds of [steel]The 3 mm thick S460MC and S700MC steel samples were butt welded using laser and hybrid LasTIG technology. All experiments were performed with constant laser power of 1.5 kW and welding speed 20 mm s 1.This combination results in heat input (laser power divided by welding speed) 75 J mm 1 for single laser welding. Argon with the flow of 18 l min 1 was applied as a shielding gas

    THE GRAIN COARSENING AND SUBSEQUENT D

    In heavy steel sections, fundamental properties such as strength and toughness are improved remarkably by refining and homogenizing the final ferrite microstructure. Conventionally, the microstructural refinement of the final ferrite depends mainly on the austenite grain size, morphology and composition prior to the phase transformation as well as the cooling rate during the transformation.[plate]Synchrotron Investigation on the Precipitation Behaviour [steel]The precipitation and dissolution behavior of niobium carbo nitrides is of particular interest for many technical applications. Niobium microalloyed high strength low alloy (HSLA) steels are widely used in civil construction, automobile and line pipe applications. These steels rely on thermomechanical processing. In this context, coupled processes like thin slab casting and thermomechanical [plate]Niobium Carbide Precipitation in Microalloyed Steel [steel]Dec 13, 2016 · Di Guobiao, Shen Qinyi, Liu Meiyan, Jia Tao, Ma Qingshen, Liu Zhenyu, Precipitation Behavior of CarbonNitrides in Microalloyed Offshore Platform Plate, HSLA Steels 2015, Microalloying 2015 & Offshore Engineering Steels 2015, 10.1002/9781119223399, (1071 1077), (2015).

    Materials Free Full Text The Impact of Isothermal

    Isothermal treatment affects the microstructural evolution and the precipitation behavior of high strength low alloy (HSLA) steels. In this regard, thermal simulation of different isothermal treatment temperatures was adopted by using a thermomechanical simulator. The results showed that hardness reached the maximum value at 600 °C holding temperature, which was related to a finer grain [plate]Investigations on the effect of heating temperature and [steel]Investigations on the effect of heating temperature and cooling rate on evolution of microstructure in an + titanium alloy Volume 33 Issue 8 Aman Gupta, Rajesh Kisni [plate]Strain rate controlled Gleeble experiments to determine [steel]In order to generate a material data base for computational welding mechanics, temperature and strain rate dependent stress strain experiments were performed by using a Gleeble ® 3500 testing system. The object of the investigation was HSLA transformable steel S960QL and related solid phases as bainite, martensite and austenite.

    Roles of Microalloying Elements in Hydrogen Induced

    The effects of alloying elements such as niobium, copper, chromium, molybdenum, and titanium in high strength, low alloy (HSLA) steels on hydrogen induced cracking (HIC) were investigated. The HIC test was performed to NACE TM 02 84 in BP (saturated H 2 S synthetic sea water) and NACE solutions. The test data were analyzed with an optical [plate]Nonlinear dynamic analysis for a rectangular HSLA steel pla[steel]Investigation on thermomechanical behavior of a HSLA steel circular plate under impact load.
