不(bu)銹鋼鍛件的耐熱(re)性能

耐(nai)熱(re)性能(neng)(neng)是指在(zai)高溫(wen)下，既有化或(huo)耐(nai)氣體介質腐蝕的(de)性能(neng)(neng)（即熱(re)穩定性)，同(tong)時(shi)又(you)有足夠的(de)強(qiang)度(du)（即熱(re)強(qiang)性）。不(bu)銹(xiu)鋼除了不(bu)生銹(xiu)外，還具有優良的(de)耐(nai)高、低溫(wen)性能(neng)(neng)、許多不(bu)銹(xiu)鋼可兼作謝熱(re)鋼或(huo)低溫(wen)訊(xun)使(shi)用。

作為耐熱鋼(gang)(gang)使用的(de)不銹(xiu)鋼(gang)(gang)，多(duo)為含碳量數(shu)高的(de)鐵(tie)素(su)體(ti)，馬氏體(ti)和(he)奧氏體(ti)不銹(xiu)鋼(gang)(gang)，它們具(ju)有下列特點。

1. 保證化性能需較高含(han)銘量以形(xing)成致密氧化膜(mo)(mo)(mo)。這種合(he)金氧化膜(mo)(mo)(mo)具(ju)有良好的保護作用，從而可延長鋼材的使用壽命或提高使用溫(wen)度，在不銹鋼中，若(ruo)氧化膜(mo)(mo)(mo)主要以(Fe. Cr)zO：的形(xing)式出現時，其化溫(wen)度劇變(bian)的能力(li)為(wei)。

2.保證熱強要(yao)求(qiu)的(de)措施。

a.增Ni以得到穩定的(de)奧氏體(ti)繼(ji)織，利用Mo.W固溶強(qiang)化，提高原子(zi)間結(jie)合(he)力(li)，但加Mo對化性不利。

b.形成碳(tan)化物(wu)(MC.MaCe)為主的第二相，為此應適當提高含碳(tan)量。

c.加入微量硼或稀以控制品(pin)粒(li)度并(bing)強化(hua)品(pin)界(jie)，如(ru)耐熱奧氏(shi)體不銹鋼(gang)06Cr15Ni25Ti2MoAIVB.

3.高(gao)溫(wen)膽化問題。 一般由表(biao)層或者表(biao)面(mian)下(xia)(xia)某些缺陷形成游紋(wen)，裂紋(wen)在(zai)交變(bian)載荷作用(yong)下(xia)(xia)，筒類鍛件定制費用(yong)，逐漸擴大，直至斷裂。

鍛(duan)件冷卻(que)初期，表(biao)層(ceng)首(shou)先冷卻(que)產(chan)生體(ti)積(ji)收(shou)(shou)縮(suo)，由(you)于(yu)試樣(yang)(yang)心(xin)部(bu)溢(yi)度(du)下降(jiang)較少，體(ti)積(ji)收(shou)(shou)縮(suo)相(xiang)應(ying)(ying)(ying)也較小，這樣(yang)(yang)在(zai)同一試樣(yang)(yang)上(shang)內外收(shou)(shou)縮(suo)不同則(ze)相(xiang)互之間發(fa)生作用(yong)力(li)。試樣(yang)(yang)表(biao)面的(de)收(shou)(shou)縮(suo)將受到心(xin)部(bu)的(de)阻(zu)礙，于(yu)是(shi)在(zai)試樣(yang)(yang)表(biao)層(ceng)產(chan)生拉(la)應(ying)(ying)(ying)力(li)、心(xin)部(bu)為壓應(ying)(ying)(ying)力(li)。此應(ying)(ying)(ying)力(li)值隨若溢(yi)度(du)的(de)升高(gao)而增加，當應(ying)(ying)(ying)力(li)超(chao)過心(xin)部(bu)的(de)屈服強度(du)時，試樣(yang)(yang)發(fa)生表(biao)足拉(la)伸、心(xin)部(bu)壓縮(suo)的(de)塑性(xing)變(bian)形。

變形的(de)(de)(de)結果(guo)使內(nei)應力(li)得到(dao)一定程(cheng)度的(de)(de)(de)松弛、應力(li)值降低。當表面溫度接近室(shi)溫或淬火冷卻(que)介質的(de)(de)(de)溫度時(shi)，心(xin)部以相對快的(de)(de)(de)速度冷卻(que)收(shou)縮，但此時(shi)心(xin)部的(de)(de)(de)收(shou)縮又受(shou)到(dao)表層的(de)(de)(de)牽(qian)制，結果(guo)試樣(yang)內(nei)形成(cheng)與冷卻(que)階段初期(qi)方向相反的(de)(de)(de)內(nei)應力(li)，即在(zai)表層產生壓(ya)應力(li)、心(xin)部為拉(la)應力(li)。由于試樣(yang)溫度已(yi)經很低，鋼(gang)的(de)(de)(de)屈服強(qiang)度明顯升高(gao)，熱應力(li)不再(zai)引起塑性變形， 這樣(yang)的(de)(de)(de)應力(li)分(fen)布就(jiu)被保留下來(lai)成(cheng)為殘留應力(li)。因此，熱應力(li)作用的(de)(de)(de)結果(guo)是(shi)使鍛件(jian)表面呈壓(ya)應力(li)狀(zhuang)態。

鍛件缺陷與材料特性不同(tong)而引起的超聲波(bo)變化。

超聲(sheng)(sheng)檢(jian)測主要應用(yong)超聲(sheng)(sheng)波在(zai)材料(liao)中(zhong)的傳播(bo)(bo)特性，以及超聲(sheng)(sheng)波與缺陷的相互作用(yong)機理(li)來進行檢(jian)測。理(li)論上，超聲(sheng)(sheng)波在(zai)大均勻介(jie)質中(zhong)是沿直線傳播(bo)(bo)的。但(dan)實際上，任何介(jie)質總有邊界(jie)，當(dang)超聲(sheng)(sheng)波在(zai)非(fei)均勻介(jie)質中(zhong)傳播(bo)(bo)，或從1種介(jie)質傳播(bo)(bo)到另(ling)1種介(jie)質時，由(you)于介(jie)質的聲(sheng)(sheng)阻(zu)抗發生(sheng)了變(bian)化，故超聲(sheng)(sheng)波會在(zai)聲(sheng)(sheng)阻(zu)抗改變(bian)的分界(jie)面上產生(sheng)反射、折射和透射現象(xiang)。

在(zai)超聲(sheng)(sheng)波(bo)(bo)透過(guo)界面(mian)時(shi)(shi)，其方向(xiang)、強度和(he)波(bo)(bo)形(xing)的(de)(de)(de)(de)(de)變化(hua)取決于2種(zhong)(zhong)介(jie)質(zhi)(zhi)的(de)(de)(de)(de)(de)特(te)性聲(sheng)(sheng)阻(zu)抗和(he)入射(she)波(bo)(bo)與分(fen)(fen)界面(mian)的(de)(de)(de)(de)(de)相(xiang)(xiang)對方向(xiang)。 當(dang)超聲(sheng)(sheng)波(bo)(bo)垂(chui)直入射(she)在(zai)2異種(zhong)(zhong)介(jie)質(zhi)(zhi)的(de)(de)(de)(de)(de)分(fen)(fen)界面(mian)上時(shi)(shi)，會產(chan)生反射(she)和(he)透射(she)現象。反射(she)是超聲(sheng)(sheng)波(bo)(bo)從1種(zhong)(zhong)介(jie)質(zhi)(zhi)入射(she)到具有不同聲(sheng)(sheng)特(te)性阻(zu)抗的(de)(de)(de)(de)(de)另1種(zhong)(zhong)介(jie)質(zhi)(zhi)時(shi)(shi)，改變傳播方向(xiang)返(fan)回原介(jie) 質(zhi)(zhi)的(de)(de)(de)(de)(de)現象;而透射(she)則是在(zai)2種(zhong)(zhong)介(jie)質(zhi)(zhi)聲(sheng)(sheng)阻(zu)抗相(xiang)(xiang)同或者相(xiang)(xiang)近時(shi)(shi)，超聲(sheng)(sheng)波(bo)(bo)穿過(guo)分(fen)(fen)界面(mian)進入另一介(jie)質(zhi)(zhi)的(de)(de)(de)(de)(de)現象。
