Abstract
A high speed gas quenching dilatometer useful in studying phase transformations in low alloy steels is described. Changes in specimen length are measured by means of an electrical micrometer tube. The maximum instantaneous cooling rate is approximately 5000°F per sec; the maximum average cooling rate from 1650° to 950°F is approximately 2900°F per sec. Data for steels of 0.11 pet and 0.67 pet C content are included.
