A formal mathematical approach to cooling curve analysis of multiple simultaneous transformations is introduced for the first time. The goal of this methodology is to measure individual phase fractions during free cooling. ...

Minor changes in the composition of the steel defined in any welding procedure will have a major effect on the final properties of the welded part. Constant cooling transformation diagrams (CCT) are used to determine the ...

Minor changes in the composition of the steel defined in any welding procedure will have a major effect on the final properties of the welded part. Continuous cooling transformation diagrams (CCT) are used to determine the ...

Dilatometry and calorimetry are well-established techniques, and have been used successfully

for decades; however, they are seldom used to quantify the progress of a transformation. Most

often, these techniques ...

For processing parts made from medium carbon steel, toughness and flexibility are of importance. Therefore, to achieve these properties, the cementite in the steels is spheroidized through heat treatment. Different parameters ...

A novel mathematical approach for the independent quantification of phase fractions in multiple simultaneous phase transformations is introduced. The proposed dilation curve analysis is very general, relying only on raw ...

Dilatometry and cooling curve analysis (CCA) are two methods of determining the evolution of a phase transformation with temperature. The two methods are similar conceptual in that they take an indirect measure of the ...

This paper analyzes the start of the martensitic transformation in 4140 steel from the point of view of six definitions, and discusses in detail the implications based on the better understanding of progression of the ...
