Austenite

04/05/2023 - "Following double welding thermal cycle, with second peak temperature in the range between Ac1 and Ac3, the IC GC HAZ undergoes a strong loss of toughness and fatigue resistance, mainly caused by the formation of residual austenite (RA). "
01/04/2023 - "Even if the fatigue crack grew, the stress intensity factor range of 0.12C-3.13Mn steel was obviously wider than that of AISI 4330 steel due to the presence of reversed austenite and secondary cracks. "
01/01/2022 - "In fatigue crack growth, the prevalence of one mechanism over the other critically depends on the crack size and the mechanical stability of the parent austenite phase. "
04/01/2020 - "The elastic anisotropy and heterogeneity effects of coarse-grained austenite on ultrasonic propagation significantly undermine the effectiveness of ultrasonic property-based fatigue damage evaluation. "
01/25/2020 - "The test results show that when the test temperature is higher than Austenite finish temperature (Af), the fatigue properties of SMAs are significantly affected by temperature. "

08/12/2018 - "Using the device on a high-energy beamline during in situ thermal treatment, we were able to extract the evolution of the stress tensor components in all phases: austenite, TiC, and even during the martensitic phase transformation of the matrix."
09/28/2023 - "The obtained results show that the microstructure of TiC-reinforced 17-4PH stainless steel composites mainly consists of austenite. "
12/14/2021 - "With Ti content increasing, the austenite phase content decreases, while the contents of ferrite phase and TiC phase increase. "
01/05/2018 - "With increasing titanium concentration in the molten pool, fractions of TiC and retained austenite increase and the shape of TiC particles changes from cubic to dendritic form. "
12/14/2021 - "The results show that Fe-25Mn-9Al-8Ni-1C-xTi alloy mainly contains austenite phase, ferrite phase and TiC phase. "

06/20/2023 - "Under the action of the laser-induced shock wave, the grain size of the LC sample surface was refined, the low-angle grain boundaries on the surface layer increased significantly, and the austenite grain length was reduced from 30-40 μm in the deep layer to 4-8 μm in the surface layer. "
11/21/2018 - "In the loading process of a shock wave, B2 austenite is transformed into B19' martensite, whereas in the unloading process of the shock wave, B19' martensite is transformed into B2 austenite. "
07/18/2021 - "The results show that only a small amount of B2 austenite is transformed into B19' martensite when the NiTi sample does not pass through the void during impact compression, whereas when the shock wave passes through the hole, a large amount of martensite phase transformation and plastic deformation is induced around the hole; the existence of phase transformation and phase-transformation-induced plastic deformation greatly consumes the energy of the shock wave, thus making the width of the wave front in the subsequent propagation process wider and the peak of the foremost wave peak reduced. "
12/01/2012 - "The results showed that there were no obvious changes of the phase transformation temperatures and shape memory characteristics of the NiTi alloy after the MAO surface modification and the coating could withstand the thermal shock and volume change caused by martensite-austenite phase transformation. "

04/01/2022 - "M23C6 was found in all creep conditions until rupture, mainly at prior austenite grain boundaries and sub-boundaries. "

01/05/2023 - "Here, the objective was to improve the corrosion resistance of UNS S32750 weld beads by increasing the volumetric austenite percentage in the fusion zone (FZ) with a hybrid process of GTAW (gas tungsten arc welding) and pulsed laser Nd-YAG (neodymium-doped yttrium aluminum garnet). "
