“…By selecting a suitable tool hardening time, it is possible to achieve an ultimate strength of 1440 MPa at a ductility of 16%. The higher ductility value of the medium manganese steels is due to the multiphase structure of these steels, which consists of a martensitic matrix with a small proportion of ferrite and residual austenite, which is mostly found along the boundaries of the martensitic needles [ 1 ] ( Figure 18 ). The occurrence of residual austenite along the boundaries of martensitic needles in this type of steel was also confirmed in the study [ 31 ].…”

“…This industry has an annual demand for pressed products of around 58% of all world production. This figure increases by leaps and bounds every year [ 1 ]. The automotive industry is pushing forward the development of advanced high-strength steels (AHSS) that features good strength, ductility, and formability [ 2 , 3 , 4 ].…”

“…By contrast, the kinetics of the reverse conversion from martensite to austenite is slow at low temperatures. When the annealing temperature is increased, the kinetics of the conversion of atomic diffusion of manganese and carbon becomes faster [ 1 , 6 ].…”

Medium manganese steels fall into the category of modern third-generation high-strength steels. Thanks to their alloying, they use a number of strengthening mechanisms, such as the TRIP and TWIP effects, to achieve their mechanical properties. The excellent combination of strength and ductility also makes them suitable for safety components in car shells, such as side reinforcements. Medium manganese steel with 0.2% C, 5% Mn, and 3% Al was used for the experimental program. Sheets with a thickness of 1.8 mm without surface treatment were formed in a press hardening tool. Side reinforcements require various mechanical properties in different parts. The change in mechanical properties was tested on the produced profiles. The changes in the tested regions were produced by local heating to an intercritical region. These results were compared with classically annealed specimens in a furnace. In the case of tool hardening, strength limits were over 1450 MPa with a ductility of about 15%.

“…Finally, the real calculations show results of 94.46% compliance and 5.54% non-compliance, which indicates that the simulated process resembles the real process. Las técnicas de simulación cuentan con gran aceptación en las industrias, debido a que pueden emular dentro de un equipo de cómputos, con un muy alto grado de precisión cualquier proceso [1]. En ella, según [2,3], se podrán describir estructuras complejas, estudiar los efectos externos e internos de un sistema, además de permitir el estudio detallado de un sistema, para poder llegar a mejorarlo.…”

Con el paso del tiempo, se ha vuelto muy imprescindible el uso de herramientas tecnológicas para analizar procesos. Por ello, en este proyecto se realizará un comparativo entre los resultados reales de un proceso de corte en frío de láminas de acero, desarrollado en una empresa de la industria metalmecánica, mediante el uso de máquinas automatizadas, y los resultados obtenidos de la simulación del proceso en el software Arena®. Se inicia con la observación del proceso de corte convencional de rollos de láminas de acero en frío, que se llevó a cabo en un período de 8 horas, equivalente a una jornada laboral. Una vez observadas y analizadas todas las actividades, se registraron los datos obtenidos. Posteriormente, se diseñó la simulación del proceso de producción, para comparar la similitud entre los resultados del modelo simulado, vs los resultados del modelo real. Los resultados del modelado simulado arrojaron valores conformes del 95% con un 5% de no-conformes. Finalmente, los cálculos reales muestran resultados de 94,46% de cumplimiento y 5,54% de incumplimiento, lo que indica que el proceso simulado se asemeja al proceso real.
