局部淬火金属柱壳破碎性的研究
Fragmentation of Metal Cylindrical Shell Treated by Local Quenching
摘要
Abstract
The fragmentation and penetration of the 40Cr steel cylindrical shells preformed by local quenching technology were studied experimentally.Through scanning electron microscopy (SEM) analysis,it is found that the microstructure of hardened layer in the cylindrical shell is predominantly needle and lath type martensite,and it is more refined and brittle than bulk material.Based on the per-formance difference,the steel cylindrical shell fractures along the designed path during the expansion process.The mass distribution of the preformed fragments is relatively uniform and the penetration also meets the requirement,which can provide reference for design of ammunition.关键词
