冷弯变形
相关语句
  cold bending deformation
     During cold bending deformation,stress concentration first causes sulfide inclusion to crack or makes inclusions separate from metal matrix and generate micro holes which increase in size continuously with deforming process,form microcracks and internal cracks when connected together,and then the cracks further expand causing medium and heavy plate to crack at cold bending.
     在冷弯变形过程中,应力集中首先使硫化物夹杂裂开,或使夹杂与金属基体分离产生显微孔洞,这些孔洞随变形过程不断长大、联接形成显微裂纹和内裂,然后进一步扩展导致中厚钢板的冷弯开裂。
