（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。

洛氏硬度計(jì)可以用于模具鋼材的硬度檢測，供貨狀態(tài)的模具鋼硬度在187至285HBS之間，可以用洛氏硬度計(jì)的HRB及HRC標(biāo)尺來測試。測試后經(jīng)查表將洛氏硬度值換算成布氏硬度值，仍然具有相當(dāng)高的精度。這種洛氏硬度計(jì)也是采用了一個(gè)C型架結(jié)構(gòu)，C型架開口尺寸為200mm和500mm，模具鋼的厚度只要小于這個(gè)尺寸就可以測試，儀器測試精度可以達(dá)到1.0HRC，換算成布氏硬度的誤差大約是5至7HBS。完成了機(jī)械加工的模具鋼材料要進(jìn)行淬火回火處理，再經(jīng)過精磨和拋光就可成為成品模具。淬火回火處理后的模具硬度檢測更為重要，因?yàn)檫@時(shí)的材料硬度是一個(gè)非常重要的質(zhì)量指標(biāo)，它在很大程度上決定了成品模具的使用壽命。

偏析即鋼的成分與組織不均勻性的表現(xiàn)，這是在模具鋼的低倍組織的檢驗(yàn)中常存在的一種缺陷。是鋼錠在凝固過程中形成的，與鋼的化學(xué)成分和澆注溫度等有關(guān)。一般分為樹枝狀的偏析、方形偏析、點(diǎn)狀偏析等。由于樹枝狀的偏析的存在，使負(fù)然各個(gè)不同的方向的力學(xué)性能表現(xiàn)出明顯的差異。方形偏析是由于鑄錠結(jié)晶時(shí)，在柱狀晶的末端與錠心等軸晶區(qū)間，聚集了較多的雜質(zhì)和孔隙而形成的。嚴(yán)重的方形偏析，對鋼材的質(zhì)量的影響是顯著的，特別是切削加工量很大的零件或心部受力的模具零件。偏析除了影響模具鋼力學(xué)性能的等向性外，對模具的拋光性能也有一定的影響。因此，國外相關(guān)的標(biāo)準(zhǔn)中有嚴(yán)格的規(guī)定。
