Determination of Ms temperature: Methods, meaning and influence of 'slow start' phenomenon
Cooling Curve Analysis as an Alternative to Dilatometry in Continuous Cooling Transformations
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 transformation and extract...
A new approach to quantifying steel response for welding procedure design
-alloys database v7.1 predictions, and the martensitic transformation will be compared with dilatometry. A major benefit of this method is that it can be performed at negligible cost. Our conclusion is that quantification of intermediate stages of transformation...
Phase Transformation Study of Aluminium Containing Ductile irons by Dilatometry
The temperature for the start of martensite formation (MS) for three Al-alloyed ductile irons containing 0.48%Al, 4.88%Al and 6.16%Al were determined by high-speed dilatatometry. Microscopic observation also were used to ...
Phase Transformation Study of Aluminium Containing Ductile irons by Dilatometry
The temperature for the start of martensite formation (MS) for three Al-alloyed ductile irons containing 0.48%Al, 4.88%Al and 6.16%Al were determined by high-speed dilatatometry. Microscopic observation also were used to ...
Quantification of evolution of multiple simultaneous phase transformations using dilation curve analysis (DCA)
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 ...
A comparison of common and new methods to determine martensite start temperature using a dilatometer
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 ...
Determination of martensite start temperature using an electromagnetic nondestructive technology
Assessment of martensite start temperature in alloy steels is of critical importance for many industrial
applications of hardenable steels. To determine this, dilatometry is often carried out by characterizing the
volume changes...
