Influence of boron content on the fracture toughness and fatigue crack propagation kinetics of bainitic steels [PDF]

, 2016
The relatively good combination of high strength and ductility makes bainitic steels a candidate to replace many other steels in industrial applications. However, in service, ductility and strength are not up to standard requirements.

Microstructure-Properties Relationship and Mechanical Stability of Retained Austenite in Thermomechanically Processed Medium-C TRIP Steel at Different Deformation Temperatures [PDF]

Archives of Metallurgy and Materials, 2020
The paper presents the effect of deformation temperature on the mechanical stability of retained austenite in a multiphase TRIP steel. Series of static tensile tests were carried out in the temperature range –20 to 140°C in order to simulate the ...

Austenite formation from a steel microstructure containing martensite/austenite and bainite bands

Journal of Materials Research and Technology, 2023
In many commercial steel processing routes, steel microstructures are reverted to an austenitic condition prior to the final processing steps. Understanding the microstructure development during austenitization is crucial for improving the performance ...

Microstructural characterization of AISI 431 martensitic stainless steel laser-deposited coatings [PDF]

, 2011
High cooling rates during laser cladding of stainless steels may alter the microstructure and phase constitution of the claddings and consequently change their functional properties.

Retained Austenite: Transformation-Induced Plasticity

, 2016
The deformation-induced phase transformation of metastable austenite to martensite is accompanied by macroscopic plastic strain and results in significant work hardening and the delayed onset of necking. Steels that exhibit such transformation-induced plasticity (TRIP) effect possess high strength–ductility ratios and improved toughness.

Simulating the Effects of Substrate Pre-Heating on the Final Structure of Steel Parts Built by Laser Powder Deposition [PDF]

, 2004
Tool steel parts built by laser powder deposition often present a heterogeneous distribution of properties caused by the complex structural transformations that occur during the deposition process.

Retained austenite and tempered martensite embrittlement in medium carbon steels [PDF]

Metallurgical Transactions A, 1983
Electron microscopy, diffraction and microanalysis, X-ray diffraction, and auger spectroscopy have been used to study quenched and quenched and tempered 0.3 pct carbon low alloy steels. Somein situ fracture studies were also carried out in a high voltage electron microscope.

Characterisation of PVD-TiN coated austempered ductile iron: Effects of nodule count and austempering temperature [PDF]

, 2011
In this work PVD-TiN coatings are deposited on ADI substrates austempered at 280 and 360°C, with nodule counts varying between 490 and 1 100 nod/mm2. The deposition is performed at 300°C by the arc ion plating technique.

Enabling bainitic transformation acceleration and mechanical properties improvement in ultrafine bainitic steel

Journal of Materials Research and Technology
A novel approach involving the fast heating of cold-rolled pearlite followed by low-temperature isothermal transformation (FBT) was devised to address the technical challenges of long processing times and strength-ductility trade-off in ultrafine ...
