چکیده
This study presents a striking advance in investigating the influence of heat treatment on microstructure and properties high strength low-alloyed steels obtained using various technologies. In contrast to normalization treatment, application thermo-mechanical control process (TMCP) offers higher characteristics but less stable during consequent high-temperature treatment. It has been established that mechanical both are up 650 °C. With an increase temperature, TMCP steel (grade S460M) strongly degraded, while normalized S355J2) remains 950 is attributed intensive grain growth at temperature than A c3 for microstructural stability steel. shown structural controlled by number factors such as heating holding time, growth, accumulated strain, presence deformation texture, deoxidation, dissolution/uncontrolled precipitations. The raw/processed data required reproduce these findings cannot be shared this time due technical or limitations. • decrease T > growth. dislocation density, dissolution precipitates induces under heating. provided austenite. Zener pinning effect plays key role preventing grains c3.

Effect of Heat Treatment on Microstructure, Magnetic and Mechanical Properties of HSLA-100
In this study, the effects of various heat treatments on microstructure, mechanical and magnetic properties of HSLA-100 steel were evaluated. The heat treatments consisted of austenitizing at 900°C for 60 minutes, then quenching by different cooling rates via furnace, air, oil and water; and quenched specimens were aged at 600°C for one hour. Optical and field emission scanning electron m...
متن کاملEffect of Heat Input on Microstructure and Mechanical Properties in Friction Stir Welding of HSLA-60
High-strength low alloy steels are a class of steels used in applications that require high strength and good weldability, including ship hulls, gas pipelines and oil industry. One way to build parts is fusion welding that create areas with a large grain size in the heat-affected zone and increased susceptibility to hydrogen cracking. One way to solve this problem is to use solid state friction...
