“…5). It has been described in detail the process of forming martensite on austenitic steel 304 produced through a cold deformation process [13], [14]. The extremely low ability of martensite in low-alloy steels to subsequent plastic deformation triggers the softening behavior of the steels as has been reported by [7]- [9].…”

“…This amplification mechanism can be attributed to a decrease in the distance between the phases in the area around the grain boundaries, which effectively allows the dislocation motion to be hindered, leading to an increase in the high dislocation density. In addition, the distortion of the atoms in the austenite matrix triggers the carbon atoms to form martensite (lath ε-martensite) [13], [14]. Therefore, hardening through the dislocation-strain coupling mechanism results in a large residual compressive stress in the axial direction [15], [16] and the formation of ε-martensite solid solution particles is the main source of increasing the mechanical strength of 304SS under cold tensile conditions.…”

The mechanical properties of stainless steel at high temperatures are important parameters of the refractory design of stainless-steel structures. In this study, the mechanical properties of SS304 colddrawn austenitic stainless grade at high temperature and room temperature were investigated experimentally. Thermal strain testing and total deformation of temperature transient conditions were carried out. The young modulus of maximum tensile is determined and the yield strength is determined using the 0.2% offset method. Temperature variables in this test are 25 °C, 100 °C, 200 °C, 300 °C, 400 °C, 500 °C, 600 °C, 700 °C, 800 °C, and 900 °C. In the thermal tensile test results, the specimen at 25 ° C has the highest ultimate voltage (σu), which is 698.33 MPa. Effect of temperature on the strength of SS304 stainless grade dramatically in the temperature range >700 °C. High temperatures reduce steel properties to a relatively greater degree, resulting in a decrease in the mechanical properties of stainless steel SS304 grade followed by relatively low steel ductility capabilities. SEM results explain that the formation of ε-martensite resulting from cold plastic deformation can lead to failure of the material at the total deformation of transient temperatures at low temperatures. The high chromium (Cr) content (~18%. wt) in grade CD 304 SS can be the main trigger for the formation of Cr-carbide precipitates formed in austenite grains or grain boundaries.

“…Furthermore, the formability and also the microstructure of the material is influenced. This influence on the material properties depends on the process parameters like deformation degree or feed velocity as shown for the material AISI 304 [4]. Processes like rotary swaging, which cause mechanical deformation also on the microscale, can induce a transformation of this austenitic stainless steel into martensite.…”

“…Processes like rotary swaging, which cause mechanical deformation also on the microscale, can induce a transformation of this austenitic stainless steel into martensite. This change of microstructure influences the mechanical behavior of the produced workpieces [4]. The lower the infeed velocity during rotary swaging the higher the hardness compared to the initial state [5].…”

The influence of microstructure deformation on the corrosion resistance of cold formed stainless steel

Rotary swaging is an incremental cold forming process to produce axisymmetric workpieces from rods and tubes. The process also induces changes of the microstructure of the material depending on the process parameters. This in turn influences the mechanical properties like hardness as well as the electrochemical properties. As a result of changed electrochemical properties, the passivity of the material and thus the corrosion behavior changes. In order to investigate the influence of rotary swaging on the corrosion behavior of the stainless steel AISI304, deformed micro parts are electrochemically analyzed. The measurements reveal a dependency of corrosion rate and impedance on both feed velocity and final diameter of the rotary swaging process. A higher feed velocity decreases the corrosion rate and increases the impedance indicating a better resistance against corrosion as a side effect of rotary swaging.

“…The most representative AUST. SSs are the 3XX series steel grades, which have wide application in nuclear reactor [60], food [61] and automobile industry [62]. The most evident feature of L-IP (lightweight steel with induced plasticity) steels is their lower density than that of other AHSSs or conventional steels [63][64][65], which attracted a lot of attention from automobile manufacturers.…”

Además, la respuesta del acero Q&P se examinó cuidadosamente en una amplia gama de tasas de deformación (10 −4 -10 3 s −1 ) mediante el uso de una máquina universal de ensayos, un sistema de barra de tensión dividida Hopkinson (SHTB) y una técnica de correlación de imagen digital (DIC). El límite elástico (YS) del acero Q&P en pruebas dinámicas (500 -1000 s −1 ) es 200 MPa más alto en comparación con las pruebas estáticas (10 −4 y 10 −2 s −1 ), mientras que la resistencia a la tracción final (UTS) tiende a aumentar linealmente con la velocidad de deformación. La fracción de austenita retenida (RA) disminuye exponencialmente con el aumento de la deformación plástica durante las pruebas de tracción estáticas y dinámicas.
