Quenching and partitioning (Q&P) process: A critical review of the competing reactions

Abstract: The quenching and partitioning (Q&P) process has been proposed recently as an alternative route to obtain a unique microstructure consisting of decarburised martensite and retained austenite that results in a superior balance between strength and ductility. The stabilisation of austenite after the Q&P processing is mainly achieved through its carbon enrichment as a result of carbon partitioning from primary martensite formed during initial quenching. However, carbon partitioning is usually accompanied … Show more

“…During plastic deformation, retained austenite undergoes a strain-induced martensite, known as the transformation-induced plasticity (TRIP) effect. This transformation reduces local stress concentration and delays microcrack formation [ 35 , 36 , 37 ]; thus, improving the material’s elongation [ 34 , 35 , 36 , 37 , 38 , 39 ]. In addition, soft-phase ferrite bears more strain leading to yielding of the material, while hard-phase martensite bears more stress.…”

“…Ejemplo de lo expuesto anteriormente son los aceros avanzados de alta resistencia procesados por temple -partición y las aleaciones de alta entropía [218,[226][227][228][229][230], los cuales, podrían solucionar las dificultades presentadas anteriormente.…”

“…Los aceros avanzados de alta resistencia mecánica procesados por temple y partición buscan retener la mayor fracción posible de austenita fuera de su rango de equilibrio termodinámico, encontrándose en condición metaestable [230]. Esta transformación metaestable, permitiría absorber grandes cantidades de energía durante la deformación y es aplicable al área automotriz para la reducción de peso.…”
