鍛件余熱淬(cui)火后(hou)力學(xue)性(xing)能會受(shou)到哪些(xie)因素的影(ying)響？

淬火介質(zhi) 

淬火介(jie)質(zhi)不僅影響(xiang)鍛件力學性能，還可能產生變形和裂紋(wen)，所(suo)以必須選(xuan)擇合適的淬火介(jie)質(zhi)，并維護(hu)和保養(yang)好淬火介(jie)質(zhi)。

理想(xiang)的淬(cui)火(huo)介質(zhi)冷(leng)卻特(te)性：碳鋼和低(di)合金鋼在650℃以上奧氏體比較穩定，以較慢的速(su)度冷(leng)卻，以減少工件因(yin)內外(wai)溫差而引起(qi)的溫度應(ying)力；在650℃~450℃，要求有足夠快的冷(leng)卻速(su)度（超過臨界冷(leng)卻速(su)度）低(di)于(yu)400℃應(ying)該緩慢冷(leng)卻，以減少組(zu)織應(ying)力，防止過大變形和淬(cui)裂(lie)。

淬火冷(leng)卻(que)時，為獲(huo)得馬氏體(ti)或(huo)貝氏體(ti)組(zu)織，必須快(kuai)冷(leng)。但同樣(yang)是獲(huo)得馬氏體(ti)，各種鋼的臨界冷(leng)卻(que)速度(du)卻(que)不一樣(yang)，過(guo)快(kuai)冷(leng)卻(que)，會(hui)造成內(nei)部應力(li)過(guo)大，引起變形(xing)甚至(zhi)開(kai)裂。

鍛造鍛件時常見的低倍缺陷有(you)哪些？

殘(can)余(yu)縮孔(kong)是鋼(gang)材中(zhong)不允許(xu)的(de)冶(ye)金缺陷。因(yin)為(wei)殘(can)余(yu)縮孔(kong)是夾雜和(he)氣體聚集的(de)地方，在(zai)(zai)(zai)進一步(bu)熱加工中(zhong)往往擴(kuo)展(zhan)成裂紋，破壞(huai)了鋼(gang)材的(de)連續性(xing)。在(zai)(zai)(zai)澆鑄鋼(gang)錠(ding)時(shi)采取措施，使縮孔(kong)集中(zhong)在(zai)(zai)(zai)鋼(gang)錠(ding)冒口部位，并且在(zai)(zai)(zai)鑄錠(ding)開坯時(shi)保證足夠的(de)切頭率(lv)，即可避免鋼(gang)材上的(de)殘(can)余(yu)縮孔(kong)缺陷。 

鑄錠(ding)(ding)內部(bu)(bu)通(tong)常(chang)是不致(zhi)密的(de)(de)，往往存(cun)在著(zhu)很多因收縮(suo)或其他原因而引(yin)起的(de)(de)細小(xiao)孔(kong)隙，稱為疏(shu)松(song)。疏(shu)松(song)多位于(yu)鋼(gang)錠(ding)(ding)的(de)(de)上部(bu)(bu)和中(zhong)部(bu)(bu)，縮(suo)孔(kong)附(fu)近(jin)常(chang)存(cun)在較多疏(shu)松(song)。鋼(gang)材(cai)在熱(re)加工過程中(zhong)，疏(shu)松(song)可得到很大程度的(de)(de)改善；但若原鋼(gang)錠(ding)(ding)的(de)(de)疏(shu)松(song)較為嚴(yan)重(zhong)、壓縮(suo)比不足，則(ze)在熱(re)加工后疏(shu)松(song)還會存(cun)在。鋼(gang)材(cai)中(zhong)如存(cun)在疏(shu)松(song)，會降低其力學性能，特(te)別是塑性

鍛件鍛后控(kong)溫(wen)冷卻方(fang)式有哪些？

根據非調質鋼種類和(he)鍛(duan)件內部(bu)金相(xiang)組織和(he)力學性能要求，其控(kong)溫(wen)冷卻方式有(you)：

1.箱內(nei)堆(dui)冷：鍛(duan)件鍛(duan)后(hou)直接在料(liao)箱內(nei)自然空冷，一(yi)般(ban)是(shi)硬度范圍要求較寬的非調質鋼(gang)零件。

2.傳送鏈散冷(leng)：鍛件(jian)在傳送鏈上(shang)級慢冷(leng)卻(que)，傳送鏈長度由冷(leng)卻(que)速度確定(ding)。

非調質(zhi)鋼制造的零(ling)件(jian)(jian)，經過(guo)控溫冷(leng)(leng)卻方式冷(leng)(leng)卻后，零(ling)件(jian)(jian)硬度合(he)(he)格、金(jin)相組織(zhi)合(he)(he)格，可以(yi)直接使用。但出(chu)現(xian)(xian)下列情況（種類(lei)）必(bi)須通過(guo)熱處理返修后才能使用：鍛(duan)造加熱溫度偏高，晶粒度處的鍛(duan)件(jian)(jian)；坯(pi)料重(zhong)復加熱超(chao)過(guo)兩次的鍛(duan)件(jian)(jian)；鍛(duan)造設備出(chu)現(xian)(xian)故障，生產(chan)不正常鍛(duan)件(jian)(jian)；未經控溫冷(leng)(leng)卻線冷(leng)(leng)卻鍛(duan)件(jian)(jian)；出(chu)現(xian)(xian)有較多粒狀貝氏體，金(jin)相組織(zhi)不合(he)(he)格鍛(duan)件(jian)(jian)；硬度偏高或偏低不合(he)(he)格鍛(duan)件(jian)(jian)。
