摘要
The invention relates to a method for determining ductile-brittle-transition-temperature (DBTT) of a steel sample, the method comprises steps of calculating fracture strength of a first notched steel sample at a first temperature, calculating yield strength of a second steel sample at the said first temperature, repeating step (a) and step (b) for considerable number of times for different temperatures and extrapolating fracture strength and yield strength over strength-temperature graph to determine DBTT of the steel sample.
