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(lái)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(guò)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。

熱作模具鋼廠家的這款熱作模具鋼產(chǎn)品具有很高的抗沖擊能力，適合有高抗沖擊需求的客戶鍛造模具時(shí)使用。并且這款熱作模具鋼除了具備高抗沖擊性外還擁有足夠的韌度和抗疲勞性，能夠承受長(zhǎng)時(shí)間的沖擊而不會(huì)出現(xiàn)損壞，這是熱作模具鋼為了適應(yīng)模具廠家的需求而研發(fā)出的新產(chǎn)品，此前的熱作模具鋼產(chǎn)品往往都不具備這樣的性能而不能滿足客戶的需要。熱作模具鋼廠家生產(chǎn)的中耐熱韌性鋼的成分中除了含有少量的碳外還包含了一些金屬材料，屬于一種特殊的合金產(chǎn)品。通常適用于模具客戶，這款產(chǎn)品的堅(jiān)硬度和耐磨性都達(dá)到了極高的程度，被很廣地使用于熱擠壓模具精鍛模具以及有色金屬壓模等產(chǎn)品的制造并且其優(yōu)異的性能受到了客戶的一致稱贊。熱作模具鋼廠家的這款產(chǎn)品是在中耐熱韌性鋼的基礎(chǔ)上進(jìn)行了改良，對(duì)其含碳量和合金材料的配比進(jìn)行了調(diào)整，從而使其保持了極高的耐熱能力，在溫度極高的環(huán)境下不會(huì)產(chǎn)生變形和疲勞，能夠使用在高溫下的熱作模具的制造，另外鋁合金壓鑄模具也適用這種材料。

碳化物是絕大多數(shù)模具鋼的必需組分，除可溶于奧氏體的碳化物外，還會(huì)有部分不能溶于奧氏體的殘留碳化物。碳化物的尺寸、形態(tài)、分布對(duì)模具鋼的使用性能等有十分重要的影響。關(guān)于碳化物的尺寸、形狀和分布是與鋼的冶煉方法、鋼錠的凝固條件以及熱加工變形條件等有關(guān)。過(guò)共析鋼的碳化物可能在晶界形成風(fēng)狀碳化物或是在加工變形中碳化物被拉長(zhǎng)而形成帶狀碳化物或者二者兼有，萊氏體模具鋼中，存在一次碳化物和二次碳化物，在熱變形的過(guò)程中，網(wǎng)狀的共晶碳化物大多可以破碎，碳化物先沿變形方向延伸，產(chǎn)生帶狀，隨著變形程度的增加，碳化物變得均勻、細(xì)小。碳化物的不均勻性對(duì)淬火變形、開裂、鋼材的力學(xué)性能的影響較大。

</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。
