An analysis was made for the fracturefeatures at T_c~* (cryogenic brittleness-characteristic temperature) at which the fractureload reaches a valley value. Furthermore, according to the experimental resultsand engineering design practice, a concept of criticai notch (crack) size for cryogenicbrittleness, a_c, as well as its limit Value, a_c~*, was put forward and recommendedto be a basic characteristic parameter for controlling the brittleness. Mathematicalderivation was carried out to give the expression of a_c and a_c~*, the reliability ofwhich was verified by the modeling tests under both static and cyclic loadingconditions. Key words:  low carbon steel      cryogenic brittleness      notch size      Received:  18 June 1988      Service E-mail this article Add to citation manager E-mail Alert RSS （） Articles by authors URL:  https://www.ams.org.cn/EN/     OR     https://www.ams.org.cn/EN/Y1988/V24/I6/432 1 涂铭旌,鄢文彬,低合金钢低温脆性断裂研究文集,西安交通大学出版社,1985:1--13 2 Knott J F.
