塑性与韧性是衡量金属材料质量的重要指标之一,但在设计计算时一般却不当作计算指标来考虑。这篇文章通过具体实验,以敢想敢干的精神,摆脱了传统观点的束缚,对冲击韧性的使用阶值提出了新的论点。这种精神是值得提倡的.欢迎有关方面对这个问题展开讨论与研究,以贯彻“百花齐放,百家争鸣”的精神。今后,本刊准备组织对若干技术上的新问题,在实践的基础上开展群众性的论争。希望大家对这一工作予以大力支特,尤其欢迎勇跃投稿,参加论争。
Plasticity and toughness is one of the important indicators to measure the quality of metal materials, but it is generally not considered as a calculation index in the design calculation. This article through specific experiments, dare to think of the spirit of dare to do, get rid of the shackles of the traditional viewpoints, the impact of the use of order of toughness put forward new arguments. This spirit is worthy of promotion and welcomes the parties concerned to discuss and study this issue so as to carry out the spirit of “letting all flowers bloom and all schools contend.” In the future, this magazine prepares to organize a number of technical new issues and conduct mass debates on the basis of practice. I hope everyone will give strong support to this work. In particular, we welcome your contributions and participation in the debate.
