Some primary results were shown that its highest fracture toughness was evaluated by the specimens of sorbitie structure tempered at 600℃, but the lowest up to about 300℃. An identical variation is noted between the impact toughness of the fatigue precracked specimens and the fracture toughness from tri-point bending tests. Moreover, the numeral estimation for the various fractured surface characteristics with relation to fracture toughness has been attempted. 收稿日期: 1981-03-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 张振芳 张天宜 刘民治 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1981/V17/I3/271 [1] Knott, J.
