“…Changes in properties due to plastic deformation as a manifestation of increasing steel strength through cold tensile manufacturing processes contribute to changes in plastic properties that can be observed in the plastic strain zone area. The same behavior is shown by cold-tensile low-carbon steel (CDS 1018) [6]. In contrast to the elastic zone region (Fig.…”

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.

This work continued to discuss the forms of Bi particles accompanying sulphide, and analysed the effect of Bi on tensile and machining properties in 1215MS free-cutting steel. The machining and tensile tests were carried out based on the as-cast steels. The effect of Bi on the size and hardness of sulphide was investigated. Results show that at 200 ppm Bi or more, the normalised frequency of the large-sized sulphide inclusions with area of above 50 μm 2 was maximum, 0.35. In Bicontaining steels, the forms of sulphide inclusions were summarized that: clustering, rodlike, long strip, spindle, ellipsoidal, and spherical shape. Most Bi particles adhering to sulphide inclusions mainly existed in steels. The average hardness of steel matrix and the inclusions in 240 ppm Bi steel were 103 and 116 kgf mm −1 , respectively. Bi added to steel increased the ductility and improved the surface finish of the machining steels.

“…The element stiffness is reduced to a very small fraction (1%) of the original value to enable material separation. The temperature-dependent material properties of the Al and the steel rivet are summarized in Table 1 based on available data from the open literature [33][34][35][36][37]. The yield strength refers to the strength at 0.2% of strain, and the hardening behavior was modeled as linear hardening.…”

Unique friction-based self-piercing riveting (F-SPR) was employed to join high-strength, low-ductility aluminum alloy 7055 for lightweight vehicle applications. This study aimed to maximize the joint strength of the AA7055 F-SPR joint while avoiding cracking issues due to low ductility at room temperature. A fully coupled Eulerian–Lagrangian (CEL) model was employed to predict the process temperature during F-SPR, and the temperature field was then mapped onto a 2D axisymmetric equivalent model for accelerated numerical analysis. The geometry, dimensions, and material strength of the rivet, as well as the depth of the die cavity and plunging depth, were investigated to enhance joint formation. Also, a static finite-element analysis model was developed to predict and analyze the stress distribution in the rivet under different mechanical testing loading conditions. Overall, the numerical model showed good agreement with the experiment results, such as joint formation and mechanical joint strength. With the aid of virtual fabrication through numerical modeling, the joint design iterations and process development time of F-SPR were greatly reduced regarding the goal of lightweight, high-strength aluminum joining.
