【摘要】 通过试验并运用爆炸冲击动力学理论对 NK- EH5 0 0调质钢爆炸硬化进行了深入的研究 ,结果表明 ,金属材料存在硬化极限 ,调整炸药组成改变爆炸硬化可以满足不同金属材料的硬化要求 ,隔离式爆炸硬化有利于保护硬化工件外观的完整性。本研究对拓展爆炸硬化在实践中的应用领域具有重要的理论指导意义。更多还原

【Abstract】 Hardness of NK EH500 steel after the explosion hardness experiments was studied by use of shock dynamics theories. The results show that the hardness of metal material is limit by explosion hardening ,the Varied hardness can be acquired by changing the constitutes of explosive in order to adjust explosion pressure and the duration, test isolation benefit protecting the complete appearance of workpiece. It is theoretically significant to the development of material explosion hardening in application.更多还原
