the oxidized layer is very thick. Thus, high-temperature annealing should include bright annealing. Key words: 304 austenitic stainless steel; work hardening; annealing softening; deformation twinning... of reverted austenite was achieved at an annealing temperature of 750 ℃ for a dwelling time of 30 min, and austenite grains with an average grain size of 1.7 μm composed approximately 95......
annealing at temperatures below 900℃, the hardness and ultimate tensile strength of 0.12%ADSC decrease slightly with increasing of annealing temperature, and at 900℃, 0.12%ADSC can still maintain more... with increasing of annealing temperature. The microstructure observation(Fig.5) shows that the dislocation cell structure is remained in the specimen after annealing at temperature of 900℃. The variations......

, GAO Wei-na, FU Wen-jie, LI Hui, Lü Li-qiang (Western Titanium Technologies Co., Ltd., Xi’an 710201, China) Abstract: The influences of heat treatments, such as annealing temperature, holding time, annealing way and cooling rates on the microstructure and room temperature mechanical properties of TC4 titanium alloy sheet were studied. The results show that the tensile strength and yield strength......
precipitates are responsible for the high coercivity at both room and high temperature. Magnetic analysis shows that the remanence Br enhances from 0.625T to 0.845T with the annealing time increasing from 10 to 30 h. The intrinsic coercivity Hci reaches the maximum value of about 2417.9 kA/m at room temperature and 693.5 kA/m at 500 ℃ after annealing for 20 h. Key words: Sm2Co17-based high temperature......

The hardness variations of cold-rolled alloy plates during annealing.... It was found that the dispersed Al3(Sc, Zr) particles could pin dislocations, stabilize substructures and impede the movement of boundaries. The ambient and elevated temperature properties of alloy with Al3......
