</p> <p> 模具鋼材的硬度如何檢測(cè)？硬度是模具鋼重要的性能之一，對(duì)于快速、精確地測(cè)試模具鋼材硬度在模具制造和使用單位是非常關(guān)鍵的。同時(shí)也具有十分重要的意義，它可以提升模具質(zhì)量、制造水平和延長(zhǎng)模具的使用壽命。模具鋼是模具工業(yè)的主體材料，根據(jù)模具的服役條件、環(huán)境和狀態(tài)的不同，模具鋼應(yīng)具備不同的特性。在工業(yè)生產(chǎn)中，模具使用壽命和制成零件的精度、質(zhì)量、外觀性能，除與模具的設(shè)計(jì)技術(shù)、制造精度，以及機(jī)床精度和制造操作有關(guān)外，正確地選用模具材料和正確地執(zhí)行熱處理工藝也是至關(guān)重要的，資料顯示，模具早期失效因材料選擇不當(dāng)和材料內(nèi)部缺陷引起的大約占百分之十左右，而由熱處理不當(dāng)引起的約占百分之四十九。硬度是模具材料和成品模具的重要性能指標(biāo)。模具在工作時(shí)的受力狀態(tài)是復(fù)雜的，如熱作模具通常是在交變的溫度場(chǎng)下承受交變應(yīng)力作用，因此它應(yīng)具有良好的阻止模具轉(zhuǎn)變成較軟或塑性狀態(tài)的能力，進(jìn)口模具鋼定制，并且在長(zhǎng)期工作環(huán)境下仍保持模具的形狀和尺寸精度不變。一般成品模具的硬度，進(jìn)口模具鋼定制，進(jìn)口模具鋼定制，冷作模具常選擇在59至60HRC，熱作模具常選擇在48HRC左右。

1）超深冷能提高DC53模具鋼模具鋼及DY-SKH51高速鋼的硬度，韌性得到更充分的保證（在超深冷過程中是殘余碳化物轉(zhuǎn)變?yōu)轳R氏體）。 </p> <p> 2）超深冷也能讓DC53模具鋼模具工件具有精度保持性（尺寸穩(wěn)定性），防止在室溫因殘留奧氏體轉(zhuǎn)變而發(fā)生尺寸變化。 </p> <p> 3）深冷處理也能促使未轉(zhuǎn)變的奧氏體更多地轉(zhuǎn)變成馬氏體，進(jìn)一步提高硬度，從而提高零件的耐磨性和使用壽命；促進(jìn)微細(xì)碳化物的彌散析出，可以DC53模具鋼圓鋼的韌性。 </p> <p> <br /> </p> <p> <br />

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(duì)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(duì)模具的拋光性能也有一定的影響。因此，國(guó)外相關(guān)的標(biāo)準(zhǔn)中有嚴(yán)格的規(guī)定。

洛氏硬度計(jì)可以用于模具鋼材的硬度檢測(cè)，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(cè)試。測(cè)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(cè)試，儀器測(cè)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(cè)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。

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 />

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。
