當今高強鋼、超高強鋼很好的實現(xiàn)了車輛的輕量化，提高了車輛的碰撞強度和安全性能，因此成為車用鋼材的重要發(fā)展方向。但隨著板料強度的提高，傳統(tǒng)的冷沖壓工藝在成型過程中容易產(chǎn)生破裂現(xiàn)象，無法滿足高強度鋼板的加工工藝要求。在無法滿足成型條件的情況下，國際上逐漸研究超高強度鋼板的熱沖壓成形技術(shù)，濟寧模具鋼加工。該技術(shù)是綜合了成形、傳熱以及組織相變的一種新工藝，主要是利用高溫奧氏體狀態(tài)下，濟寧模具鋼加工，板料的塑性增加，屈服強度降低的特點，通過模具進行成形的工藝。但是熱成型需要對工藝條件、金屬相變、CAE分析技術(shù)進行深入研究，濟寧模具鋼加工，該技術(shù)被國外廠商壟斷，國內(nèi)發(fā)展緩慢。

碳化物是絕大多數(shù)模具鋼的必需組分，除可溶于奧氏體的碳化物外，還會有部分不能溶于奧氏體的殘留碳化物。碳化物的尺寸、形態(tài)、分布對模具鋼的使用性能等有十分重要的影響。關(guān)于碳化物的尺寸、形狀和分布是與鋼的冶煉方法、鋼錠的凝固條件以及熱加工變形條件等有關(guān)。過共析鋼的碳化物可能在晶界形成風狀碳化物或是在加工變形中碳化物被拉長而形成帶狀碳化物或者二者兼有，萊氏體模具鋼中，存在一次碳化物和二次碳化物，在熱變形的過程中，網(wǎng)狀的共晶碳化物大多可以破碎，碳化物先沿變形方向延伸，產(chǎn)生帶狀，隨著變形程度的增加，碳化物變得均勻、細小。碳化物的不均勻性對淬火變形、開裂、鋼材的力學性能的影響較大。

（1）模腔表層金屬產(chǎn)生熱疲勞（龜裂）。熱作模具的工作特點是具有間歇性．每次使熱態(tài)金屬成形后都要用水、油、空氣等介質(zhì)冷卻模腔的表面。因此．熱模的工作狀態(tài)是反復受熱和冷卻，從而使模腔表層金屬產(chǎn)生反復的熱脹冷縮，即反復承受拉壓應力作用．其結(jié)果引起模腔表面出現(xiàn)龜裂，稱為熱疲勞現(xiàn)象，由此，對熱模具鋼提出了第二個基本使用性能要求．即具有高的熱疲勞抗力。一般說來，影響鋼的熱疲勞抗力的因素主要有：①鋼的導熱性。鋼的導熱性高，可使模具表層金屬受熱程度降低，從而減小鋼的熱疲勞傾向性。一般認為鋼的導熱性與合碳量有關(guān)，含碳量高時導熱性低，所以熱作模具鋼不宜采用高碳鋼。在生產(chǎn)中通常采用中碳鋼（C0.3%5～0.6%）合碳量過低．會導致鋼的硬度和強度下降．也是不利的。②鋼的臨界點影響。通常鋼的臨界點（Acl）越高．鋼的熱疲勞傾向性越低。因此．一般通過加入合金元素Cr、W、Si、引來提高鋼的臨界點。從而提高鋼的熱疲勞抗。
