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.

Evaluation of the Austenitic Grain Growth by Thermoelectric Power Measurements [PDF]

Materials Science Forum, 2004
The influence of the deformation grade on the recrystallised grain size has been studied in the AISI 304 stainless steel. Therefore, cold rolled samples of this material with reductions varying between 30% and 80% were annealed at different temperatures and subsequently quenched. The mean austenitic grain sizes were measured and compared. Moreover, the

Critical Examination of the Representativeness of Austenite Grain Growth Studies Performed In Situ Using HT-LSCM and Application to Determine Growth-inhibiting Mechanisms

BHM Berg- und Hüttenmännische Monatshefte
This contribution critically addresses the potential of HT-LSCM experiments for in situ observations of austenite grain growth (AGG). By quantifying AGG for various alloys, the impact of impurity induced solute drag effects (SDE) and second phase ...

Precipitation Criterion for Inhibiting Austenite Grain Coarsening during Carburization of Al-Containing 20Cr Gear Steels

Metals, 2021
AlN precipitates are frequently adopted to pin the austenite grain boundaries for the high-temperature carburization of special gear steels. For these steels, the grain coarsening criterion in the carburizing process is required when encountering the ...

The Austenite Grain Growth Behavior and Mathematical Model of 20CrMnTiH [PDF]

Proceedings of the 2nd Annual International Conference on Advanced Material Engineering (AME 2016), 2016
The 20CrMnTiH gear steel was heated at temperature range from 850°C to 1250°C and at holding time range from 0s to 480s to obtain the law of austenite grain growth by using Gleeble-3500 thermo-simulation-machine in this research. The effects of heating temperature and holding time on austenite grain growth behavior were investigated.
