Description / Abstract:
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.
This practice includes requirements for obtaining metallographic
information to be used as a supplement to the dilatometry
measurements.
The values stated in SI units are to be regarded as standard. No
other units of measurement are included in this standard.
This standard does not purport to address all of the safety
concerns, if any, associated with its use. It is the responsibility
of the user of this standard to establish appropriate safety and
health practices and determine the applicability of regulatory
limitations prior to use.
