（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(chēng)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(shuō)來(lái)，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(guò)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(guò)加入合金元素Cr、W、Si、引來(lái)提高鋼的臨界點(diǎn)。從而提高鋼的熱疲勞抗。

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(hù)來(lái)咨詢(xún)模具鋼深冷處理工藝，模具鋼深冷處理溫度等等之類(lèi)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。
