潤(rùn)色一句有關(guān)材料裂紋的表述,謝謝。 已有2人參與
|
| 金屬材料在制造和使用過(guò)程中出現(xiàn)的微裂紋、孔洞等缺陷逐步演變會(huì)導(dǎo)致材料的失效破壞,因此掌握這些微觀缺陷的演變規(guī)律對(duì)于材料的正確使用有著積極的指導(dǎo)作用。 |

The evolution of these defects will gradually lead to the invalidation of materials. Therefore, a comprehension of evolution rule of these micro defects plays a positive leading role in correct usage of the materials. |

| The defects of metallic materials such as micro-crack and hole, appeared in the process of manufacture and service would evolve gradually and finally result in the failure. Thus,it has a positive role in guiding the proper use of these materials to grasp the evolution rule of these micro-defects. |
