鍛件的(de)試驗方(fang)法有(you)哪些？

復試

若由于試(shi)驗設備(bei)(bei)故障(zhang)，或試(shi)樣制備(bei)(bei)不正確，以及與材料無關的(de)(de)傷痕，致使某一試(shi)樣的(de)(de)性能值未(wei)能滿足規定(ding)的(de)(de)要求，則該(gai)試(shi)驗廢棄，可在鍛件中(zhong)該(gai)試(shi)樣的(de)(de)相(xiang)鄰位置重新取樣試(shi)驗。

拉伸試(shi)(shi)(shi)(shi)驗(yan)(yan)時，若試(shi)(shi)(shi)(shi)樣(yang)在標(biao)距外(wai)(wai)或(huo)在標(biao)距中心到標(biao)距點的(de)(de)距離的(de)(de)1/2以外(wai)(wai)處斷裂，且試(shi)(shi)(shi)(shi)驗(yan)(yan)結果又不符合規(gui)定(ding)要求時，則該試(shi)(shi)(shi)(shi)樣(yang)無效，可在鍛件(jian)中該試(shi)(shi)(shi)(shi)樣(yang)的(de)(de)相鄰位(wei)置重新取樣(yang)試(shi)(shi)(shi)(shi)驗(yan)(yan)。

若(ruo)試樣(yang)不(bu)是由于鍛件中白點或裂紋(wen)等原因，而未能滿(man)足規定的要(yao)求，則鍛件可不(bu)經重新(xin)熱處理，在該試樣(yang)的相鄰位置取雙倍試樣(yang)復試，此兩試樣(yang)均應滿(man)足規定的要(yao)求。

若鍛件(jian)的(de)強(qiang)度性(xing)能(neng)指標較高，但(dan)塑性(xing)、韌性(xing)指標未能(neng)滿足(zu)規(gui)定的(de)要求時，可對鍛件(jian)進行(xing)補(bu)充回(hui)火(huo)，餅(bing)類鍛件(jian)鍛造廠家(jia)，補(bu)充回(hui)火(huo)的(de)次數不作(zuo)限(xian)制。回(hui)火(huo)后按原規(gui)定進行(xing)試驗(yan)。

若(ruo)鍛件(jian)的(de)力學性能試驗結(jie)果未能符合規定(ding)(ding)的(de)要求(qiu)，制造廠(chang)可對鍛件(jian)進(jin)行重新(xin)熱處理，按原規定(ding)(ding)進(jin)行試驗。未經需方許可，重新(xin)熱處理次數不得(de)超(chao)過2次。

鍛件缺陷與(yu)材料(liao)特(te)性(xing)不(bu)同而引起(qi)的超(chao)聲波變化(hua)。

超(chao)聲(sheng)(sheng)(sheng)檢(jian)測主(zhu)要應用超(chao)聲(sheng)(sheng)(sheng)波在(zai)材(cai)料(liao)中(zhong)的(de)(de)傳(chuan)(chuan)播(bo)(bo)(bo)特性，以及(ji)超(chao)聲(sheng)(sheng)(sheng)波與(yu)缺陷的(de)(de)相互作(zuo)用機(ji)理(li)來進行(xing)檢(jian)測。理(li)論上，超(chao)聲(sheng)(sheng)(sheng)波在(zai)大均勻介(jie)質(zhi)中(zhong)是沿直線傳(chuan)(chuan)播(bo)(bo)(bo)的(de)(de)。但實際上，任何介(jie)質(zhi)總(zong)有邊界(jie)，當超(chao)聲(sheng)(sheng)(sheng)波在(zai)非均勻介(jie)質(zhi)中(zhong)傳(chuan)(chuan)播(bo)(bo)(bo)，或從(cong)1種介(jie)質(zhi)傳(chuan)(chuan)播(bo)(bo)(bo)到(dao)另1種介(jie)質(zhi)時，由于介(jie)質(zhi)的(de)(de)聲(sheng)(sheng)(sheng)阻抗發生了變化，故超(chao)聲(sheng)(sheng)(sheng)波會在(zai)聲(sheng)(sheng)(sheng)阻抗改變的(de)(de)分界(jie)面上產生反射(she)、折射(she)和透射(she)現象。

在(zai)(zai)(zai)超聲(sheng)(sheng)波透過界面(mian)時，其方(fang)向(xiang)(xiang)、強度(du)和(he)波形的變化取決于2種(zhong)介(jie)(jie)質(zhi)(zhi)(zhi)的特(te)性聲(sheng)(sheng)阻(zu)抗和(he)入射(she)波與分(fen)(fen)界面(mian)的相對方(fang)向(xiang)(xiang)。 當超聲(sheng)(sheng)波垂(chui)直入射(she)在(zai)(zai)(zai)2異種(zhong)介(jie)(jie)質(zhi)(zhi)(zhi)的分(fen)(fen)界面(mian)上(shang)時，青海鍛(duan)件(jian)鍛(duan)造廠家，會產生反(fan)(fan)射(she)和(he)透射(she)現(xian)象。反(fan)(fan)射(she)是超聲(sheng)(sheng)波從1種(zhong)介(jie)(jie)質(zhi)(zhi)(zhi)入射(she)到(dao)具(ju)有不同(tong)聲(sheng)(sheng)特(te)性阻(zu)抗的另(ling)1種(zhong)介(jie)(jie)質(zhi)(zhi)(zhi)時，改變傳播方(fang)向(xiang)(xiang)返(fan)回原介(jie)(jie) 質(zhi)(zhi)(zhi)的現(xian)象;而透射(she)則是在(zai)(zai)(zai)2種(zhong)介(jie)(jie)質(zhi)(zhi)(zhi)聲(sheng)(sheng)阻(zu)抗相同(tong)或者相近時，超聲(sheng)(sheng)波穿過分(fen)(fen)界面(mian)進入另(ling)一介(jie)(jie)質(zhi)(zhi)(zhi)的現(xian)象。

鍛件鍛后控溫冷卻方式有哪(na)些(xie)？

根據非調質鋼種類和鍛件內部(bu)金相組(zu)織和力(li)學性能要求，其控(kong)溫冷卻方式(shi)有：

1.箱內(nei)堆(dui)冷：鍛件(jian)鍛后(hou)直接在料箱內(nei)自然空(kong)冷，一般是硬度范圍要求較寬的(de)非調(diao)質鋼零件(jian)。

2.傳送(song)(song)鏈散冷(leng)：鍛(duan)件在傳送(song)(song)鏈上(shang)級慢冷(leng)卻(que)，傳送(song)(song)鏈長度(du)由冷(leng)卻(que)速(su)度(du)確定。

非(fei)調質鋼制造的零(ling)件(jian)，經(jing)過(guo)控溫冷卻(que)方式冷卻(que)后，零(ling)件(jian)硬度(du)合(he)(he)(he)(he)格(ge)、金相組織合(he)(he)(he)(he)格(ge)，可以(yi)直接使(shi)用(yong)(yong)。但出(chu)現(xian)下列情況（種類）必(bi)須通(tong)過(guo)熱(re)處理返修后才(cai)能使(shi)用(yong)(yong)：鍛(duan)(duan)造加熱(re)溫度(du)偏(pian)(pian)高(gao)，晶粒度(du)處的鍛(duan)(duan)件(jian)；坯料(liao)重復加熱(re)超過(guo)兩(liang)次的鍛(duan)(duan)件(jian)；鍛(duan)(duan)造設(she)備(bei)出(chu)現(xian)故障，生(sheng)產(chan)不正常(chang)鍛(duan)(duan)件(jian)；未經(jing)控溫冷卻(que)線冷卻(que)鍛(duan)(duan)件(jian)；出(chu)現(xian)有較多粒狀(zhuang)貝氏體，金相組織不合(he)(he)(he)(he)格(ge)鍛(duan)(duan)件(jian)；硬度(du)偏(pian)(pian)高(gao)或偏(pian)(pian)低不合(he)(he)(he)(he)格(ge)鍛(duan)(duan)件(jian)。
