中文摘要 | 熱軋鋼料之表面凹痕缺陷,除經由凹痕之分佈、頻率或外觀特徵判別成因外,可 進一步藉金相觀察來判別凹痕是否在冷加工所造成。由凹痕附近之晶粒變形現象,可判定凹 痕是冷加工下所造成。缺陷樣品經適當退火處理後,若凹痕附近之晶粒出現再結晶或晶粒成 長,亦可判定凹痕是冷加工下所造成。本文試圖建立熱軋鋼料表面凹痕缺陷之成因鑑定模式 。 |
英文摘要 | The causes of depression defect on the surface of hot-rolled steel can be identified from its distribution, frequency or appearance. Furthermore, metallographic examinations could be used to idedtify whether it is a cold-worked depression or not. The distortion of ferrite grain near a depression defect is a piece of evidence of cold working. After suitable annealing, recrystalization and grain growth of ferrite grain near the depression defect are other pieces of evidence of cold working. In this paper, we try to find a suitable model to identify the causes of a depression on the surface of hot-rolled steel. |
