Resumo: This manuscript aims to present an overview of quenching and partitioning (Q&P) heat treatment usually applied to transformation-induced plasticity (TRIP) and duplex steels (DP). TRIP and DP are the first generations of advanced high-strength steels (AHSS). AHSSs present multiphase microstructures that ensure an advantageous combination of strength and ductility.  The Q&P heat treatment process aims to obtain a mixed microstructure with martensite and retained austenite and improve the relation strength/ductility of common AHSS. The retained austenite of Q&P steels is rich in carbon and stable at room temperature. The heat treatment process implicates quenching the steel between the martensite-start (Ms) and martensite-finish (Mf) temperatures, followed by partitioning.  Partitioning is an isothermal heat treatment that occurs above the Ms temperature. A diffusion process enriches the remaining austenite with carbon that migrates from martensite. The stability of retained austenite at room temperature improves the mechanical performance of steel, once it increases the material’s toughness and elongation. The optimal control of microstructure originates the third generation of AHSS and enables to reduce of weight and improved mechanical response of automotive parts made of the TRIP and DP steels.

TRIP y DP son las primeras generaciones de aceros avanzados de alta resistencia (AHSS). Los AHSS presentan microestructuras multifásicas que aseguran una combinación ventajosa de resistencia y ductilidad. El proceso de tratamiento térmico Q&P tiene como objetivo obtener una microestructura mixta con martensita y austenita retenida y mejorar la relación resistencia/ductilidad del AHSS común. La austenita retenida de los aceros Q&P es rica en carbono y estable a temperatura ambiente. El proceso de tratamiento térmico implica el enfriamiento del acero entre las temperaturas de inicio de martensita (Ms) y de final de martensita (Mf), seguido de la partición. La partición es un tratamiento térmico isotérmico que se produce por encima de la temperatura Ms. Un proceso de difusión enriquece la austenita restante con carbono que migra desde la martensita. La estabilidad de la austenita retenida a temperatura ambiente mejora el desempeño mecánico del acero, ya que aumenta la tenacidad y el alargamiento del material. El control óptimo de la microestructura da origen a la tercera generación de AHSS y permite reducir el peso y mejorar la respuesta mecánica de las piezas de automoción fabricadas con los aceros TRIP y DP.Este manuscrito tem por objetivo apresentar uma visão geral do tratamento térmico de têmpera e partição (Q&P) geralmente aplicado aos aços de transformação induzida por plasticidade (TRIP) e aços duplex (DP). Os aços TRIP e DP são a primeira geração dos aços avançados de alta resistência (AHSS). Os aços AHSS apresentam uma microestrutura multifásica que garante uma combinação vantajosa de resistência e ductilidade. O processo de tratamento térmico de Q&P tem por objetivo obter uma microestrutura composta por martensita e austenita retida, de modo a melhorar a relação resistência/ductilidade do aço AHSS. A austenita retida dos aços Q&P é rica em carbono e estável e temperatura ambiente. O processo de tratamento térmico implica em temperar o aço entre a temperatura de início de transformação martensítica, Ms, e a temperatura final da transformação martensítica, Mf. Por um processo de difusão, o carbono da martensita migra para a austenita retida. A estabilidade da austenita retida em temperatura ambiente melhora o desempenho mecânico do aço, uma vez que há um aumento em sua tenacidade e alongamento. Este controle ótimo da microestrutura originou a terceira geração dos AHSS e permite a redução de peso e a melhora nas propriedades mecânicas de peças automotivas feitas em aços TRIP e DP.Research, Society and Development2022-08-03info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/3190310.33448/rsd-v11i10.31903Research, Society and Development; Vol. 11 No. 10; e346111031903Research, Society and Development; Vol. 11 Núm. 10; e346111031903Research, Society and Development; v. 11 n. 10; e3461110319032525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/31903/27857Copyright (c) 2022 Renata Neves Penha; Yago Francisco Soares Marinshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessPenha, Renata NevesMarins, Yago Francisco Soares2022-08-12T22:23:03Zoai:ojs.pkp.sfu.ca:article/31903Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:48:04.931181Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
