Standard Practice for Quantitative Measurement and Reporting of Hypoeutectoid Carbon and Low-Alloy Steel Phase Transformations
2018
14
ASTM Vol.01.03 (2023)
This practice covers the determination of hypoeutectoid steel phase transformation behavior by using high-speed dilatometry techniques for measuring linear dimensional change as a function of time and temperature, and reporting the results as linear strain in either a numerical or graphical format.
The practice is applicable to high-speed dilatometry equipment capable of programmable thermal profiles and with digital data storage and output capability.
This practice is applicable to the determination of steel phase transformation behavior under both isothermal and continuous cooling conditions.
