不銹鋼鍛件需要加(jia)工(gong)硬(ying)化嗎？

不銹(xiu)鋼鍛件(jian)是(shi)需(xu)要加(jia)工硬(ying)(ying)化(hua)(hua)的(de)，加(jia)工硬(ying)(ying)化(hua)(hua)是(shi)一種非常(chang)重要的(de)強(qiang)化(hua)(hua)手段，可用來提高(gao)不銹(xiu)鋼鍛件(jian)材(cai)料的(de)強(qiang)度和硬(ying)(ying)度，這(zhe)對于不能(neng)用熱(re)處理方法強(qiang)化(hua)(hua)的(de)不銹(xiu)鋼鍛件(jian)尤其(qi)重要。

不銹(xiu)鋼(gang)鍛件(jian)(jian)進行加工(gong)硬化有利于不銹(xiu)鋼(gang)鍛件(jian)(jian)塑性變(bian)形加工(gong)的(de)(de)變(bian)形均勻(yun)性。因為不銹(xiu)鋼(gang)鍛件(jian)(jian)先變(bian)形部分得(de)到(dao)強化時，繼續的(de)(de)變(bian)形將主(zhu)要在末變(bian)形部分中發展，從而使(shi)不銹(xiu)鋼(gang)材料能(neng)夠均勻(yun)變(bian)形，如筒(tong)形鍛件(jian)(jian)的(de)(de)拉(la)深等(deng)，它可保證金屬零件(jian)(jian)和構件(jian)(jian)的(de)(de)工(gong)作安(an)全性。

例如零件在工作(zuo)中一旦出現超(chao)載等原因，零件某部(bu)位所(suo)受應力(li)大于其屈服點(dian)產(chan)生少量塑性變(bian)形(xing)，則(ze)因加(jia)工硬化(hua)(hua)使該部(bu)位屈服點(dian)提(ti)高(gao)(gao)，就有可(ke)能(neng)(neng)制止(zhi)該處(chu)進一步(bu)變(bian)形(xing)和斷裂. ? 但(dan)(dan)是加(jia)工硬化(hua)(hua)雖然能(neng)(neng)夠提(ti)高(gao)(gao)強度(du)，但(dan)(dan)卻降低塑性，這對于大變(bian)形(xing)量的(de)變(bian)形(xing)加(jia)工無(wu)疑會帶來麻煩(fan)。

如(ru)果(guo)要求變徑較大，因加(jia)工硬化現象(xiang)的存在就不(bu)能一次拉(la)(la)拔(ba)(ba)出來，需要多(duo)次拉(la)(la)拔(ba)(ba)，而且在兩次拉(la)(la)拔(ba)(ba)之(zhi)間必須安排消(xiao)除加(jia)工硬化的退火(huo)處理，使(shi)不(bu)銹(xiu)(xiu)鋼鍛(duan)件塑性(xing)恢復才能再進(jin)行下一次拉(la)(la)拔(ba)(ba)變徑，塑性(xing)變形不(bu)僅使(shi)不(bu)銹(xiu)(xiu)鋼鍛(duan)件機(ji)械性(xing)能顯(xian)著變化，也明顯(xian)改變不(bu)銹(xiu)(xiu)鋼鍛(duan)件的物理、化學性(xing)能。例(li)如(ru)使(shi)電阻增(zeng)大，導磁性(xing)、耐(nai)腐蝕性(xing)降(jiang)低等。

鍛(duan)造(zao)鍛(duan)件時(shi)常見的低倍缺陷有(you)哪些？

低(di)倍(bei)夾雜(za)(za)(za)(za)物(wu)(wu)(wu)(wu)(wu)分為(wei)內在夾雜(za)(za)(za)(za)物(wu)(wu)(wu)(wu)(wu)與外(wai)來(lai)夾雜(za)(za)(za)(za)物(wu)(wu)(wu)(wu)(wu)兩種。內在夾雜(za)(za)(za)(za)物(wu)(wu)(wu)(wu)(wu)是(shi)鋼(gang)在冶(ye)煉及(ji)(ji)(ji)凝固(gu)過程中(zhong)(zhong)，由于復雜(za)(za)(za)(za)的(de)化學(xue)反應結果生成(cheng)(cheng)的(de)一些化合(he)物(wu)(wu)(wu)(wu)(wu)，在鋼(gang)液(ye)凝固(gu)時來(lai)不及(ji)(ji)(ji)上(shang)浮而嵌(qian)于鋼(gang)中(zhong)(zhong)，如氧化物(wu)(wu)(wu)(wu)(wu)、硅酸鹽、硫化物(wu)(wu)(wu)(wu)(wu)、氮化物(wu)(wu)(wu)(wu)(wu)等屬于這類夾雜(za)(za)(za)(za)物(wu)(wu)(wu)(wu)(wu)。但(dan)這類夾雜(za)(za)(za)(za)物(wu)(wu)(wu)(wu)(wu)一般(ban)比(bi)較細小且彌散分布(bu)于鋼(gang)中(zhong)(zhong)而成(cheng)(cheng)為(wei)高倍(bei)夾雜(za)(za)(za)(za)物(wu)(wu)(wu)(wu)(wu)，只(zhi)有在少數情況(kuang)下聚(ju)集而成(cheng)(cheng)低(di)倍(bei)夾雜(za)(za)(za)(za)物(wu)(wu)(wu)(wu)(wu)。因而低(di)倍(bei)夾雜(za)(za)(za)(za)物(wu)(wu)(wu)(wu)(wu)常(chang)見的(de)還是(shi)外(wai)來(lai)夾雜(za)(za)(za)(za)物(wu)(wu)(wu)(wu)(wu)。外(wai)來(lai)夾雜(za)(za)(za)(za)物(wu)(wu)(wu)(wu)(wu)是(shi)冶(ye)煉或(huo)澆(jiao)注設備上(shang)剝落的(de)耐火(huo)材料或(huo)未脫(tuo)凈(jing)的(de)爐渣(zha)及(ji)(ji)(ji)摻入(ru)(ru)的(de)其他異物(wu)(wu)(wu)(wu)(wu)，在鋼(gang)液(ye)凝固(gu)時嵌(qian)入(ru)(ru)鋼(gang)中(zhong)(zhong)形成(cheng)(cheng)的(de)，有時也稱為(wei)夾渣(zha)。

低(di)倍(bei)夾(jia)雜物破壞了金(jin)屬組織的(de)連續性，使(shi)鋼的(de)性能降低(di)。由于它很脆且硬，故在熱加工或熱處理時(shi)往往形(xing)成裂紋，鹽(yan)城(cheng)鍛(duan)件鍛(duan)造(zao)廠家(jia)，在鍛(duan)件使(shi)用(yong)過程中可(ke)能成為疲勞破壞的(de)根源。所以(yi)，鋼材或鍛(duan)件標準均規定(ding)低(di)倍(bei)酸浸試片上(shang)不(bu)允許有肉眼可(ke)見的(de)夾(jia)雜。

鋼(gang)(gang)錠(ding)(ding)(ding)在澆注過(guo)程中(zhong)，在凝固部(bu)位，由于得不(bu)到鋼(gang)(gang)液補充，形成收縮孔(kong)(kong)洞，稱為縮孔(kong)(kong)。當鋼(gang)(gang)錠(ding)(ding)(ding)熱加工(gong)成材時(shi)，要切(qie)除(chu)頭部(bu)，若(ruo)鋼(gang)(gang)錠(ding)(ding)(ding)切(qie)頭率不(bu)夠時(shi)，將會使部(bu)分縮孔(kong)(kong)殘留于鋼(gang)(gang)中(zhong)，稱之為殘余縮孔(kong)(kong)。

鍛件(jian)的試驗方法(fa)有哪(na)些(xie)？

其他試驗項目

除上述試驗(yan)項(xiang)目(mu)(mu)外，如果需方要求進行(xing)下列項(xiang)目(mu)(mu)試驗(yan)，應在訂(ding)貨時與制造廠協(xie)商，任何這(zhe)樣(yang)的協(xie)議應包(bao)括試驗(yan)程序(xu)的細(xi)節。

取(qu)樣位置、取(qu)樣數(shu)量(liang)和試樣制備

鍛件(jian)上試(shi)(shi)塊的(de)留放(fang)位置按(an)圖樣(yang)的(de)要(yao)求(qiu)決(jue)定。若圖樣(yang)未注明要(yao)求(qiu)時，可由(you)(you)制(zhi)造廠(chang)決(jue)定，但必須(xu)保證能(neng)代表鍛件(jian)的(de)力學性能(neng)。需方要(yao)求(qiu)留放(fang)復試(shi)(shi)試(shi)(shi)塊時，其試(shi)(shi)塊的(de)留放(fang)位置按(an)協議進行。鍛件(jian)不便留放(fang)試(shi)(shi)塊時，可以破(po)壞鍛件(jian)取樣(yang)，這時制(zhi)造廠(chang)應增加試(shi)(shi)驗(yan)用的(de)鍛件(jian)數量。其他特殊情(qing)況，由(you)(you)制(zhi)造廠(chang)與用戶具體(ti)議定。

試樣(yang)的切(qie)取(qu)方(fang)向(xiang)按圖樣(yang)的要求(qiu)決定，若圖樣(yang)未注明要求(qiu)時，可由制造廠(chang)自行選擇（縱向(xiang)、橫向(xiang)或切(qie)向(xiang)）。

取樣(yang)數量(liang)可從每個試塊(kuai)中切取拉伸試樣(yang)1個，沖擊試樣(yang)2個。需方根據鍛件(jian)的使用條(tiao)件(jian)，也可增加試樣(yang)數量(liang)，但(dan)應在合同或圖樣(yang)中明確(que)規(gui)定。

切(qie)取后(hou)的試(shi)樣不得作任何影響力學性能的熱處理(li)。
