由于熱作模具鋼工作條件的特點(diǎn)，因此會(huì)帶來以下方面的問題： </p> <p> （1）模腔表層金屬產(chǎn)生熱疲勞（龜裂）。熱作模具的工作特點(diǎn)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(fù)受熱和冷卻，從而使模腔表層金屬產(chǎn)生反復(fù)的熱脹冷縮，即反復(fù)承受拉壓應(yīng)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(duì)熱模具鋼提出了第二個(gè)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(dǎo)熱性。鋼的導(dǎo)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(rèn)為鋼的導(dǎo)熱性與合碳量有關(guān)，含碳量高時(shí)導(dǎo)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(huì)導(dǎo)致鋼的硬度和強(qiáng)度下降．也是不利的。②鋼的臨界點(diǎn)影響。通常鋼的臨界點(diǎn)（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(diǎn)。從而提高鋼的熱疲勞抗。

模具鋼的硬度測(cè)試主要針對(duì)三種情況，即模具鋼材料的硬度檢測(cè)，經(jīng)過熱處理的半成品模具的檢測(cè)硬度及要求高耐磨性的模具表面熱處理后的表面硬度的檢測(cè)。供貨狀態(tài)的模具鋼主要是經(jīng)過鍛造的鋼板、鋼塊或鋼棒，一般以退火狀態(tài)供貨。某些塑料模具鋼還以預(yù)硬狀態(tài)（調(diào)質(zhì)處理）供貨，用戶可直接加工成模具而不必進(jìn)行后續(xù)熱處理。模具鋼按鋼種分類可分為碳素工具鋼、合金工具鋼和高速鋼，我國GB標(biāo)準(zhǔn)對(duì)于各種模具鋼都規(guī)定了出廠硬度要求，要求對(duì)鋼材的退火硬度和試樣淬火硬度進(jìn)行檢驗(yàn)。 </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，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> <br /> </p> <p> H13鋼和3Cr2W8V鋼是我國目前使用廣的兩種熱作模具鋼，其中H13鋼因其良好的綜合力學(xué)性能及抗冷熱疲勞性能，能夠勝任一般模鍛工況的要求。但由于H13鋼作為中耐熱型熱作模具鋼，其工作溫度不宜超過600℃，且淬透性差不利于制造大截面模具，其應(yīng)用受到限制。 </p> <p> 3CrW8V鋼是我國較早使用且應(yīng)用廣的**熱性熱作模具鋼，其熱穩(wěn)定性良好，使用溫度可達(dá)650℃，但因其冷熱疲勞性能和導(dǎo)熱性差，容易因冷熱疲勞而產(chǎn)生龜裂甚至斷裂。而中合金DM鋼為某科研團(tuán)隊(duì)自主研發(fā)的新型熱作模具鋼?？蒲腥藛T通過3種熱鍛模具鋼熱穩(wěn)定曲線的測(cè)定及微觀組織的觀察，對(duì)比分析3種鋼熱穩(wěn)定性能的優(yōu)劣及在熱穩(wěn)定過程中微觀組織的變化。熱穩(wěn)定試驗(yàn)的試樣尺寸為10mm×10mm×15mm，采用S2-5-12箱式爐分別將試樣在580、620、650℃保溫24h，然后采用69-1型洛氏硬度計(jì)，按照GB/T230.1-2000測(cè)試不同溫度下3種試驗(yàn)鋼的洛氏硬度值。
