1) DWTT abnormal fracture
DWTT异常断口
2) abnormal fracture
异常断口
1.
In the light of abnormal fracture of DWTT test for high-grade pipe steel,the paper statistically analyzes the DWTT test results for X65,X70 and X80 pipe steel at a systemic temperature and studies their abnormal fracture rules.
针对高钢级管道钢在进行落锤撕裂试验(DWTT)时经常出现异常断口的现象,通过统计分析X65、X70和X80管材系列温度的DWTT试验结果,探讨了异常断口发生规律。
2.
According to different reason caused the brittle area in fracture on DWTT specimen,the appearance of abnormal fracture can be classified into three kinds,the first is isolated brittle fracture area occurred only in the area within hammering,through longer toughness stable enlarging after toughness starting fracture of sample.
根据DWTT试样断口中脆性区产生的原因不同,异常断口形貌分为三类:第一类试样韧性起裂后,经历较长的韧性稳定扩展,仅在锤击区域产生孤立的脆性断裂形貌区;第二类试样韧性起裂后,经历韧性稳定扩展,转变为脆性断裂直至试样破坏,脆性面积较大;第三类试样起裂区和锤击侧均为韧性断裂形貌,仅在试样中部核心部位产生脆性断裂区域。
3) Abnormal defect of tensile fracture
拉力断口异常缺陷
1.
Abnormal defect of tensile fracture existed in the medium thick plate is a popular phenomena in the domestic and international medium thick plate.
本文通过拉力试样断口异常缺陷理化分析及形貌特征的研究，弄清了该缺陷产生的机理，提出了改进工艺的措施，划分出五类不同形貌的断口，并验证了平台断口、开裂断口和贯穿断口是危害性能(主要是延伸率)最致命的缺陷，从而制订出了拉力断口异常缺陷形貌描述图谱及质量等级判定标准，解决了过去对此类缺陷无标准可执行的历史。
