It was found that the parameter brittlencss number can be extensi-vely applied to metallic materials. The possibility of the use of brittleness numberto deal with the ascast magnesium alloy, medium or high strength steels under thecondition of fracture at low stress has been disccused. Key words:  as-cast magnesium alloy      fracture      notch sensitivity      brittleness number      Received:  18 January 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/I1/30 1 Carpinteri A.
