②改變共析點S的位置??s小γ相區(qū)的元素,均使共析點S溫度升高;擴大γ相區(qū)的元素,則相反。此外幾乎所有合金元素均降低共析點S的含碳量,使S點向左移。不過碳化物形成元素如釩、鈦、鈮等(也包括鎢、鉬),在含量高至一定限度以后,則使S點向右移。
③改變γ相區(qū)的形狀、大小和位置。這種影響較為復雜,一般在合金元素含量較高時,能使之發(fā)生顯著改變。例如鎳或錳含量高時,可使γ相區(qū)擴展至室溫以下,使鋼成為單相的奧氏體組織;而硅或鉻含量高時,則可使γ相區(qū)縮得很小甚至完全消失,使鋼在任何溫度下都是鐵素體組織。
5、硫(S):硫在通常情況下也是有害元素。使鋼產生熱脆性,降低鋼的延展性和韌性,在鍛造和軋制時造成裂紋。硫對焊接性能也不利,降低耐腐蝕性。所以通常要求硫含量小于0.055%,優(yōu)質鋼要求小于0.040%。在鋼中加入0.08-0.20%的硫,可以改善切削加工性,通常稱易切削鋼。
