淬透性主要取決于鋼的化學(xué)成分和淬火前的原始組織狀態(tài)；淬硬性則主要取決于鋼中的含碳量。對(duì)于大部分的冷作模具鋼，淬硬性往往是主要的考慮因素之一。對(duì)于熱作模具鋼和塑料模具鋼，一般模具尺寸較大，尤其是制造大型模具，其淬透性更為重要。另外，對(duì)于形狀復(fù)雜容易產(chǎn)生熱處理變形的各種模具，為了減少淬火變形，往往盡可能采用冷卻能力較弱的淬火介質(zhì)，如空冷、油冷或鹽浴冷卻，為了得到要求的硬度和淬硬層深度，就需要采用淬透性較好的模具鋼。 [2] </p> <p> 淬火溫度和熱處理變形 </p> <p> 為了便于生產(chǎn)，要求模具鋼淬火溫度范圍盡可能放寬一些，特別是當(dāng)模具采用火焰加熱局部淬火時(shí)，由于難于準(zhǔn)確地測(cè)量和控制溫度，就要求模具鋼有更寬的淬火溫度范圍。 </p> <p> 模具在熱處理時(shí)，尤其是在淬火過(guò)程中，要產(chǎn)生體積變化、形狀翹曲、畸變等，為保證模具質(zhì)量，要求模具鋼的熱處理變形小，特別是對(duì)于形狀復(fù)雜的精密模具，淬火后難以修整，對(duì)于熱處理變形程度的要求更為苛刻，應(yīng)該選用微變形模具鋼制造 </p> <p> <br /> </p> <p> <br />

熱軋模具鋼分為錘鍛、模鍛、擠壓和壓鑄幾種主要類型，包括熱鍛模、壓力機(jī)鍛模、沖壓模、熱擠壓模和金屬壓鑄模等。熱變形模具在工作中除要承受巨大的機(jī)械應(yīng)力外，還要承受反復(fù)受熱和冷卻的作用，而引起很大的熱應(yīng)力。熱作模具鋼除應(yīng)具有高的硬度、強(qiáng)度、紅硬性、耐磨性和韌性外，還應(yīng)具有良好的高溫強(qiáng)度、熱疲勞穩(wěn)定性、導(dǎo)熱性和耐蝕性，此外還要求具有較高的淬透性，以保證整個(gè)截面具有一致的力學(xué)性能。對(duì)于壓鑄模用鋼，還應(yīng)具有表面層經(jīng)反復(fù)受熱和冷卻不產(chǎn)生裂紋，以及經(jīng)受液態(tài)金屬流的沖擊和侵蝕的性能。這類鋼一般屬于中碳合金鋼，碳質(zhì)量分?jǐn)?shù)在0.30%~0.60%，屬于亞共析鋼，也有一部分鋼由于加入較多的合金元素（如鎢、鉬、釩等）而成為共析或過(guò)共析鋼。常用的鋼類有鉻錳鋼、鉻鎳鋼、鉻鎢鋼等。 </p> <p> <br /> </p> <p> <br /> </p><p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 熱作模具鋼在服役條件下除了承受載荷的周期性變化之外，還受到高溫及周期性的急冷急熱的作用，因此，評(píng)價(jià)熱作模具鋼的斷裂抗力應(yīng)重視材料的熱機(jī)械疲勞斷裂性能。熱機(jī)械疲勞是一種綜合性能的指標(biāo)，它包括熱疲勞性能、機(jī)械疲勞裂紋擴(kuò)展速率和斷裂韌性三個(gè)方面。 </p> <p> 熱疲勞性能反映材料在熱疲勞裂紋萌生之前的工作壽命，抗熱疲勞性能高的材料，萌生熱疲勞裂紋的熱循環(huán)次數(shù)較多；機(jī)械疲勞裂紋擴(kuò)展速率反映材料在熱疲勞裂紋萌生之后，在鍛壓力的作用下裂紋向內(nèi)部擴(kuò)展時(shí)，每一應(yīng)力循環(huán)的擴(kuò)展量；斷裂韌性反映材料對(duì)已存在的裂紋發(fā)生失穩(wěn)擴(kuò)展的抗力。斷裂韌性高的材料，其中的裂紋如要發(fā)生失穩(wěn)擴(kuò)展，必須在裂紋前端具有足夠高的應(yīng)力強(qiáng)度因子，也就是必須有較大的裂紋長(zhǎng)度。在應(yīng)力恒定的前提下，在一種模具中已經(jīng)存在一條疲勞裂紋，如果模具材料的斷裂韌性值較高，則裂紋必須擴(kuò)展得更深，才能發(fā)生失穩(wěn)擴(kuò)展。 </p> <p> 也就是說(shuō)，抗熱疲勞性能決定了疲勞裂紋萌生前的那部分壽命；而裂紋擴(kuò)展速率和斷裂韌性，可以決定當(dāng)裂紋萌生后發(fā)生亞臨界擴(kuò)展的那部分壽命。因此，熱作模具如要獲得高的壽命，模具材料應(yīng)具備高的抗熱疲勞性能、低的裂紋擴(kuò)展速率和高的斷裂韌性值。 </p> <p> <br /> </p> <p> <br />

模具鋼深冷處理工藝是怎樣的？深冷處理的作用性非常大，近期有很多客戶來(lái)咨詢模具鋼深冷處理工藝，模具鋼深冷處理溫度等等之類的問(wèn)題，天成模具小編在這里為大家詳細(xì)解答下，模具鋼深冷處理工藝是怎樣的。模具鋼深冷處理一般在零下196℃進(jìn)行。DC53模具鋼板材深冷正常的處理工藝如下：一般在淬火和回火工序之間進(jìn)行，也能在淬火回火之后進(jìn)行深冷處理。但是有一種情況要注意，如果在淬火、回火后鋼中仍保留有殘余奧氏體，則在深冷處理后仍需要再進(jìn)行一次回火。深冷處理能提高鋼的耐磨性和抗回火穩(wěn)定性。深冷處理不僅用于冷作模具，也可用于熱作模具和硬質(zhì)合金。

/> </p> <p> 在工作過(guò)程中，模具承受著沖擊載荷，為了減少在使用過(guò)程中的折斷、崩刃等形式的損壞，要求模具鋼具有一定的韌性。模具鋼的化學(xué)成分，晶粒度，純凈度，碳化物和夾雜物等的數(shù)量、形貌、尺寸大小及分布情況，以及模具鋼的熱處理制度和熱處理后得到的金相組織等因素都對(duì)鋼的韌性帶來(lái)很大的影響。特別是鋼的純凈度和熱加工變形情況對(duì)于其橫向韌性的影響更為明顯。鋼的韌性、強(qiáng)度和耐磨性往往是相互矛盾的。因此，要合理地選擇鋼的化學(xué)成分并且采用合理的精煉、熱加工和熱處理工藝，以使模具材料的耐磨性、強(qiáng)度和韌性達(dá)到很好的配合。
