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(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。 </p> <p> 也就是說(shuō)，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 /> </p><p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 在工作過(guò)程中，模具承受著沖擊載荷，為了減少在使用過(guò)程中的折斷、崩刃等形式的損壞，要求模具鋼具有一定的韌性。 </p> <p> 模具鋼的化學(xué)成分，晶粒度，純凈度，碳化物和夾雜物等的數(shù)量、形貌、尺寸大小及分布情況，以及模具鋼的熱處理制度和熱處理后得到的金相組織等因素都對(duì)鋼的韌性帶來(lái)很大的影響。特別是鋼的純凈度和熱加工變形情況對(duì)于其橫向韌性的影響更為明顯。鋼的韌性、強(qiáng)度和耐磨性往往是相互矛盾的。因此，要合理地選擇鋼的化學(xué)成分并且采用合理的精煉、熱加工和熱處理工藝，以使模具材料的耐磨性、強(qiáng)度和韌性達(dá)到配合。 </p> <p> 沖擊韌性系表特征材料在一次沖擊過(guò)程中試樣在整個(gè)斷裂過(guò)程中吸收的總能量。但是很多工具是在不同工作條件下疲勞斷裂的，因此，常規(guī)的沖擊韌性不能反映模具鋼的斷裂性能。小能量多次沖擊斷裂功或多次斷裂壽命和疲勞壽命等試驗(yàn)技術(shù)正在被采用。 </p> <p> <br /> </p> <p> <br />

選擇冷作模具鋼的一種基本方法是：先把除磨損外的其他失效機(jī)理全部排除，然后選擇具備適合耐磨損性的工具鋼，以滿足產(chǎn)品生產(chǎn)量的要求。如何對(duì)工具鋼的磨損判定？必須從被加工材料類型、被加工材料硬度、被加工材料是否有顆粒存在，這幾個(gè)方面判定其抗磨損能力。冷作模具鋼**擁有鋼材性能方面的知識(shí)是遠(yuǎn)遠(yuǎn)不夠的，還必須考慮生產(chǎn)零件的數(shù)量、被加工材料的類型、厚度及其硬度等因素。高生產(chǎn)數(shù)量有時(shí)需要不只一副模具才能滿足產(chǎn)量需求，因此，需要高壽命的工具鋼，以達(dá)到模具整體經(jīng)濟(jì)效益；另外，低產(chǎn)量要求的模具可使用合金工具鋼。
