Provides dilatometric data on the mechanical stabilisation of the bainite transformation when it occurs in plastically deformed austenite and on the martensite start temperature of the austenite which is left untransformed after completion of bainite transformation at 475 degrees centigrade.
The tar file has two parts :-
Part 1 contains dilatometric data on the mechanical stabilisation of the bainite transformation when it occurs in plastically deformed austenite. The data are for a Fe-0.12C-2.03Si-2.96Mn (all in wt%) steel. In all the cases the austenite was deformed at 700 degrees centigrade prior to its transformation to bainite.
Part 2 contains data on the martensite start temperature of the austenite which is left untransformed after completion of bainite transformation at 475 degrees centigrade, as a function of the plastic strain.
File bainite.mechanical.stablisation.data has the actual data, while bainite.mechanical.stabilisation.info contains an ASCII text version of this explanation.
The first part of the data has 11 separate sections, each arranged in 3 columns as follows :-
Column 1 is the dilatational strain.
Column 2 is the temperature in centigrade.
Column 3 is time in seconds during isothermal transformation.
The very first row in each of these sections gives the plastic strain prior to isothermal transformation at the stated temperature. These eleven sections represent the plots presented in Figures 2a and 2b of [1].
The second part of the data has 3 columns as follows :-
Column 1 is the austenite prestrain.
Column 2 is the martensite start temperature in centigrade of the residual austenite left untransformed after the bainite reaction has been terminated at 475 centigrade.
Column 3 is the martensite start temperature (centigrade) of austenite of the average chemical composition
These data are plotted in Figure 4 of [1].
None.
