The automotive industry has experienced rapid growth, with lightweight materials becoming a significant research focus. Among these materials, low-density Fe-Mn-Al-C alloys show promise for this kind of application. To optimize the hot workability parameters practical applications, it is essential to explore deformation behavior alloys. In study, we investigated alloy Fe-0.77Mn-7.10Al-0.45C-0.31Nb using plane-strain compression tests several temperatures (850, 950, 1050, and 1150 °C) nominal...
In the last years, press-hardening steels have contributed to automotive industry successfully meet increasing regulations for reducing fuel consumption and stringent greenhouse gas emissions while improving passenger safety by manufacturing lightweight car body parts. Zn-Fe coating is an alternative prevent corrosion or even enhance resistance in these steels. However, prone liquid melting embrittlement (LME) during hot forming process. To LME, must be fully transformed into a solid...
Precipitation of the intermetallic phases embrittles duplex stainless steels. Currently, most studies in this subject simulated aging phenomena by first holding material at different isothermal conditions and then, quenching down under high cooling rates to investigate subsequent microstructures mechanical properties. In work, specimens steel UNS S31803 were submitted cycles controlled non-isothermal conditions. The volume fraction sigma chi formed was less than 1%. value lower that assumed...
Reducing pollutant emissions and improving safety standards are primary targets for modern mobility improvement. To meet these needs, the development of low-density steels containing aluminum is a new frontier research automotive applications. Low-density Fe-Mn-Al-C alloys promising. In this regard, an alloy with high content niobium addition belonging to system was evaluated understand possible phase transformations thus obtain transformation diagram by continuous cooling help future...
The microporous structure of granular soils that provides important information such as shear strength, compressibility, and hydraulic conductivity, is directly influenced by the void ratio. Therefore, a quick identification ratio, non-destructively way in situ becomes an interesting practice. Ultrasound has been successfully used for ceramic materials, wood, concrete rocks. When dealing with soils, great efforts are made to understand its behavior characteristics through wave propagation...
