不銹鋼拉伸中導致開裂形成的原因有：奧氏體不銹鋼的冷作硬化**高；奧氏體不銹鋼為亞穩(wěn)定型，在變形時會出現(xiàn)變相，誘發(fā)馬氏體相；馬氏體相又脆，因此會容易出現(xiàn)開裂。在塑性變形中，隨著變形量的增加，誘發(fā)馬氏體含量也會隨著變形量的增加而增高，殘余應力則越大，殘余應力和馬氏體含量的關(guān)系：誘發(fā)馬氏體相含量增高，引發(fā)殘余的應力越大，在沖壓過程中便容易開裂。 </p> <p> </p> <p> 造成表面劃痕的因素有：不銹鋼拉伸件的表面會出現(xiàn)劃痕是由于工件與模具表面存在相對的移動，在一定的壓力促使下，導致坯料和模具局部表面直接產(chǎn)生摩擦，加之坯料的變形熱使得坯料和金屑熔蓋在模具的表面上，使工件外表擦傷產(chǎn)生劃痕。 </p> <p> <br /> 廣州防腐精密拉伸五金件哪里買鋁酸鹽水泥涂層或***鹽水泥涂層。</p><div
