摘　　要：研究了10CrNi3MoV船体结构钢多个位置的厚度中心拉伸及冲击性能。试验结果表明,在钢板宽度方向上,钢板中心位置的强度与两侧差异明显,钢板的冲击韧性波动较大;在钢板长度方向的强度和韧性均匀性较好。钢板宽度四分之一和中心处的明显偏析和长条形的Al2O3杂质影响了钢的性能均匀性。In this paper,the uniformity of thick 10CrNi3MoV hull structural steel plate is analysed through tensile and impact tests of multiple position.The results show that strength is obviously different between the edges the center across the width and toughness is fluctuant.The strength and toughness are quite uniform along the length.Segregation and long strip Al2O3 were found on the position of 1 /4 width and the center which may affect the uniformity of the steel.
