Xn. Cheng et al., Effect of alloying elements and temperature on impact toughness of cryogenic austenitic steels, MAT SCI E A, 311(1-2), 2001, pp. 211-216
In this paper, ductile-brittle transition law and three important character
istic parameters, i.e. impact toughness at room temperature (A(KV)(300)), d
uctile-brittle transition temperature (T-K), and gradient of transition cur
ve (K-C) are studied. According to the measured results which are processed
afterwards on the computer, quantitative expressions are obtained:
A(KV)(300) = f(Me); A(KV) = A(KV)(300)exp [-B(300-T/300)(2)].
The parameter B is also the function of alloying elements and temperature.
The calculated results are proved to be satisfactory. (C) 2000 Elsevier Sci
