前言 自高膛压火炮问世以来,高强度厚壁炮钢的强韧性关系一直是人们特别关注的问题。为了安全可靠,不同类型、不同膛压和不同强度的大口径厚壁火炮身管用钢应该有什么样的强韧性配合?采用什么方法能够比较准确而简便地确定最佳强韧性匹配关系,以便对身管用钢提出合适的强韧性要求而确保现代高膛压火炮的发展?这是当前世界各国炮钢材料和力学研究者十分重视并在不断深入研究的一个重要课题。本文介绍了高强
Preface Since the advent of high-pressure gun, the toughness of high-strength thick-wall gun steel has always been a special concern. In order to be safe and reliable, different types, different bore pressure and different strength of large caliber thick-walled barrel steel should have what kind of toughness with? With what method can be more accurate and easy to determine the optimal strength and toughness match, so that It is an important issue for the steel for body building that the appropriate requirements of toughness are put forward to ensure the development of modern high-pressure bombs. This is an important issue that the researchers of steel materials and mechanics all over the world attach great importance to and continue to do in-depth research. This article describes the high strength
