化學熱處理原理分類及應用全解析 - 鋼材知識問答系統(tǒng)│常州仁成...
化學熱處理是一種通過加熱金屬工件并在特定介質中使其表面與化學元素反應,從而改變表層成分、組織和性能的工藝。與普通熱處理不同,它通過元素擴散形成表面合金層或化合物層,實現(xiàn)“表硬內韌”的梯度性能。主要工藝包括滲碳、滲氮、碳氮共滲和滲金屬等,廣泛應用于提高耐磨性、耐腐蝕性、抗疲勞和高溫性能。例如,滲碳用于汽車齒輪,滲氮用于精密

什么是鋼材的屈服強度? - 鋼材知識問答系統(tǒng)│常州仁成金屬精密...
屈服強度是金屬材料抵抗塑性變形的關鍵指標,分為明顯和不明顯屈服現(xiàn)象兩種情況。對于無明顯屈服現(xiàn)象的材料,通常以0.2%殘余變形的應力值作為屈服強度。屈服強度的測定方法包括圖示法和指針法,影響因素包括結合鍵、組織、結構、原子本性等內在因素,以及溫度、應變速率、應
