Its purpose is to originate a uniform and stable microstructure that most closely resembles the metal's phase diagram equilibrium microstructure, thus letting the metal attain relatively low levels of hardness, yield strength and ultimate strength with high plasticity and toughness.

2024年4月1日 · The microstructure evolution and mechanical properties after annealing were systematically investigated, and the relationship between microstructure, mechanical properties, and deformation behavior was comprehensively addressed. Furthermore, the work-hardening behavior is analyzed to explain the plasticity evolution.

2024年11月25日 · To evaluate the impact of annealing treatment on the microstructures and mechanical properties, tensile tests and nano-indentation were conducted. The experimental results reveal that the higher annealing temperature (320 °C) results in reduced tensile strength, yield strength and hardness, while increasing elongation.

2023年10月17日 · The cold-rolled steel plates obtain very fine austenite grains by using microalloying of (V and Nb elements) and recrystallization annealing to achieve grain boundary strengthening. The annealed steel plate consists of a bimodal microstructure of non-recrystallized austenite grains with dense pre-dislocations and fine recrystallized grains.

2022年5月1日 · The effect of annealing temperature on the microstructure, mechanical property and anti-corrosion behavior of the X2CrNi12 ferritic stainless steel were systematically investigated. The results demonstrate that a large amount of (Fe, Cr) 23 C 6 precipitated at the ferrite grain boundaries after annealing below 740 °C.

2019年6月26日 · Annealing at 700 °C for 10 min results in an ultra-fine-grained microstructure with excellent comprehensive mechanical properties for 316LN stainless steel. (3)

2024年7月31日 · In this study, the researchers investigated the effects of annealing on the microstructure and mechanical properties of cold-rolled 20Mn23AlV non-magnetic structural steel.
