Enchancing mechanical properties and wear resistance of heavy-haul systems through complex microstructure control

Abstract: This study delves into the formulation of an advancedmicrostructure in medium-carbon high silicon spring steel through a series of engineered heat treatments. The microstructure, composed of lower bainite, proeutectoid ferrite, and pearlite, exhibits superior mechanical properties compared to traditional pearlitic steel. Specifically, the novelmicrostructure yields a strength of 870 Leia mais…

Study of the mechanical properties of some structural aluminium-steel joints

Abstract: In a world in which vehicles of higher energy efficiency have constantly been pursued, the development of multi-material structures can be extremely interesting as far as structural weight reduction and the mitigation of greenhouse gas emissions are concerned. This paper evaluates basic mechanical properties of vehicular structural joints between Leia mais…

Tailoring phase transformations in SAE 9254 steel: a dilatometry-based study on austenitization quenching, and carbon partitioning processes

Abstract: This study investigates the phase transformations and microstructural development of SAE 9254 steel subjected to various heat treatments aimed at achieving a combination of bainitic, martensitic, and retained austenitic phases. The critical austenitization and quenching temperatures, along with the holding times, were determined using a dilatometer to observe the Leia mais…
