Development of a Thermo-Metallurgical Model to Predict Heating and Austenitization of 22MnB5 for Hot Forming Die Quenching

, 2017
Hot forming die quenching (HFDQ) is used to transform ultrahigh strength steel blanks into martensitic body-in-white components that are lighter than parts made from traditional mild steels, without sacrificing crash performance.

A prediction model for austenite grain size distribution of casting slab in thermal rebound process: Considering α-ferrite precipitation and re-austenization

Journal of Materials Research and Technology
The precipitation and re-austenitization behavior of α-ferrite during thermal rebound process of casting slab are crucial to the austenite grain size distribution. Accurately obtaining austenite grain size distribution plays an important guiding role for

Anisotropic Transformation Strain and Its Consequences on Distortion during Austenitization

, 2012
The distribution of segregations, which is introduced in the continuous casting process and modified during succeeding manufacturing steps, is considered as an important "distortion potential carrier" for chemically banded steels. This article presents a

The Influence of Austenitization Temperature on the Mechanical Properties of a Prehardened Mould Steel

, 2013
The many practical difficulties and longer lead time with heat treatment of mould steels after machining have led to increased demand for steels in prehardened condition, typically ~ 40HRC.

Investigation of masking concepts for influencing the austenitization process during press hardening

, 2018
One possibility to adjust tailored properties in hot stamping is the application of a masking concept to prevent a complete austenitization. In this study different concepts were investigated in order to use them as a suitable masking. A simulation model

Hot centrifugal coating: A novel method for enhancing diffusion bonding integrity at steel-brass interfaces

Results in Surfaces and Interfaces
Steel cylinders are widely used in industry, but their service life is often limited by corrosion and wear. Conventional coating methods generally produce only mechanical bonds and can lead to delamination and interfacial failure.

Microstructure and mechanical properties of ADI depending on austenitization methods and parameters

, 2012
Ductile iron was quenched using two-variant isothermal transformation. The first treatment variant consisted of one-phase austenitization at a temperature t = 830, 860 or 900 C, cooling down to an isothermal transformation temperature of 300 or 400 C and

Prediction of critical cooling rate under rapid heating rate and short holding time for pearlitic rail steel

Journal of Materials Research and Technology
Critical cooling rate (Vc) is typically employed to assess the ability of forming martensite for pearlitic railway steels. Currently, the examination of Vc is normally conducted by dilatometry analysis under a fully austenitizing condition.
