“…According to the above analysis, it can be concluded that the 364.0°C was thought to be the beginning temperature at which α -martensite precipitated carbides and formed α-ferrite, and 509.2°C to be the finishing one. The second exothermic peak in the temperature range of 545.7°C to 581.4°C was due to the magnetic transition, and similar results were also observed by Li et al [33]. The temperature range covered by the exothermic peak in the third stage was 619.5°C to 747.4°C.…”

The effect of Cr and Ni element segregation on austenite stability and deformation mechanisms of nano/ultrafine-grained 304 stainless steel obtained by cryogenic rolling plus annealing treatment was systematically studied. The results showed that the nano/ultrafine-grained steel had a good combination of strength and ductility (yield strength ∼896 MPa, tensile strength ∼977 MPa, and elongation ∼39.6%). According to the findings, the formation of Cr segregation in the body-centered cubic structure at the intersection of austenite grain boundaries and localised austenite grains with low Ni content reduced the austenite stability of the nano/ultrafine-grained steel and promoted the generation of strain-induced martensite during plastic deformation, resulting in the deformation mechanism dominated by the transformation-induced plasticity effect.

“…Fatigue performance of Ti-3Cu(T6-16) was tested on INSTRON 8801. Specimen were prepared in accordance with National Standards and Requirements GB3075-82 [ 20 ] and ASTM E 466-96 (Reapproved 2002) [ 21 ], the minimum cross-sectional area is 6 mm in diameter, the parallel section length is 18 mm, the radius of the transition arc is 30 mm and the clamping end is 12 mm in diameter. Before test, all samples were surface polished to ensure the surface roughness Ra≤0.5 μm.…”

Previous study has shown that Ti-3Cu alloy shows good antibacterial properties (>90% antibacterial rate), but the mechanical properties still need to be improved. In this paper, a series of heat-treatment processes were selected to adjust the microstructure in order to optimize the properties of Ti-3Cu alloy. Microstructure, mechanical properties, biocorrosion properties and antibacterial properties of wrought Ti-3Cu alloy at different conditions was systematically investigated by X-ray diffraction, optical microscope, scanning electron microscope, transmission electron microscopy, electrochemical measurements, tensile test, fatigue test and antibacterial test. Heat treatment could significantly improve the mechanical properties, corrosion resistance and antibacterial rate due to the redistribution of copper elements and precipitation of Ti2Cu phase. Solid solution treatment increased the yield strength from 400 to 740 MPa and improved the antibacterial rate from 33% to 65.2% while aging treatment enhanced the yield strength to 800–850 MPa and antibacterial rate (>91.32%). It was demonstrated that homogeneous distribution and fine Ti2Cu phase plays a very important role in mechanical properties, corrosion resistance and antibacterial properties.

“…Stress levels corresponding to fatigue life of 300000 cycles was in Table 3. The results showed that the fatigue properties of the hot rolled samples were not less than those of cold rolled samples, and it can be deduced that the fatigue properties of hot rolled samples are equal to or better than those of cold rolled samples even if the tensile strength of hot rolled strips decreased to those of the cold rolled strips by modifying the producing technology [6].

The hot rolled strips for internal plates of automobile was developed by taking the technologies of low-carbon softening steel, including strictly control the chemical composition content during the steel melting and optimization of the rolling processes in the thin slab continuous casting and rolling line. The results showed that when carbon content was 0.04%, adding aluminum content or reducing silicon content and manganese content, reducing the reduction in previous rolling passes and increasing the reduction of the finishing pass at high temperature was beneficial for reducing the yield strength and tensile strength of the hot rolled strips. The precipitate of the samples after annealing showed that the precipitate of aluminum-nitride increased significantly at 850°C. And the texture of the samples after annealing showed that the main texture was {110} <001> and its intensity was 1.7-2.0, annealing with hot rolled strips did not benefit the advantageous texture. Tension-tension fatigue properties of hot rolled strips and cold rolled ones were determined, the results showed that the fatigue properties of hot rolling strips were rather higher than that of cold rolled ones. In the stamping experiments of some automobile parts, there was not any drawback, and the forming properties of hot rolling strips were equal to that of cold rolled ones. It was feasible to replace the cold rolled strips with the hot rolled ones for the internal plates of automobile.
