可伐合金常見類型：玻璃封接用鉻鐵合金<br /> 和玻璃封接用的鉻鐵合金是含鉻28%的鉻鐵合金，又稱做高鉻鋼或28號膨脹合金。合金中由于加入了鉻，使膨脹系數(shù)降低，因此可與軟玻璃進(jìn)行匹配封接。含鉻量高的鉻鐵合金，一般在室溫至熔點(diǎn)溫度的全部范圍內(nèi)將是鐵氧體的狀態(tài)，所以也稱做鐵氧體的鉻鐵合金。這種合金在封接前需在濕氫中加熱到950℃，使表面形成灰綠色的、薄而致密的CrO3及Fe2O3的氧化層，這種氧化層能很好地溶入玻璃并形成草綠色或褐綠色的封接面。這種合金的特點(diǎn)是，由于含鉻量大于28%，因而其相變點(diǎn)特別高。一般顯像管的第二陽極引線帽及彩色顯像管中屏上固定蔭罩框架的錐頭。圓掃描示波管的偏轉(zhuǎn)電極針等，以及盤形芯柱的管針，均是由高鉻鋼制的。過去當(dāng)顯像管玻璃錐體的壓制工藝未解決時(shí)，曾用高鉻鋼作成金屬錐體，再和玻璃屏進(jìn)行封接，這在一些老式顯像管中還可看到。然而必須注意，當(dāng)加熱到800-1200℃以上時(shí)，將產(chǎn)生奧斯丁體鐵，這種奧斯丁體的膨脹系數(shù)要比鐵氧體的鉻鐵合金大得多，并且在較低溫度時(shí)，仍能穩(wěn)定地保存在合金中，在這種情況下，將使膨脹系數(shù)改變，因而就會出現(xiàn)膨脹系數(shù)特性曲線不正常的危險(xiǎn)，而使材料不適合和玻璃封接。因此，鐵氧體的鉻鐵合金無論是在冶煉生產(chǎn)中或是在使用中，對于奧斯丁體的出現(xiàn)，必須給予很大的注意。<br /> 鉻鐵合金沒有氧化的危險(xiǎn)，所產(chǎn)生的綠到鼠灰色的氧化鉻及氧化鐵表面層，是非常牢固地附著在合金絲上，并且在封接過程中還可防止進(jìn)一步的氧化。 </p></div><p><img src="http://2024aiimg.qy55.com//cjjhb_soft/86/1136/202402212305197315.jpg"

19世紀(jì)初，已開始用鉑作為封接材料與軟玻璃封接。1879年，愛迪生(T.Edison)發(fā)明的白熾燈泡以及早期的電子管和X射線管通過玻璃的引出線都用鉑絲。在 1896年法國吉堯姆 (C.E.Guillaume)制成因瓦(Invar)合金(36Ni-Fe)以后,又派生出了代替鉑的46Ni-Fe封接合金，這是早的封接合金。后來進(jìn)一步改進(jìn)這種合金,在表面覆一層薄銅,這種覆銅的42Ni-Fe絲(俗稱杜美絲，Dumet Wire)用作非匹配軟玻璃封接引出線一直使用到70年代。隨著電真空技術(shù)的發(fā)展，出現(xiàn)了熔點(diǎn)高、熱穩(wěn)定性好、熱膨脹系數(shù)更低的硬玻璃。初期采用鉬或鎢與硬玻璃封接。20世紀(jì)30年代出現(xiàn)了與硬玻璃封接的稱為可伐 (Kovar)的Fe-Ni-Co合金;此外,還出現(xiàn)了與軟玻璃封接的Fe-Ni-Cr系、Fe-Cr系、Fe-Ni-Cu系等封接合金。<br /> 第二次世界大戰(zhàn)后，隨著超高頻、大功率電真空器件的發(fā)展，出現(xiàn)了與氧化鋁、氧化鈹?shù)忍沾煞饨拥暮辖?。對膨脹合金提出兼具高?dǎo)熱、高導(dǎo)電、無磁性等物理性能的要求。為此采用了復(fù)合膨脹合金（如覆銅的可伐合金帶材和絲材）、含難熔金屬的封接合金（如Ni-Mo、Ni-Mo-W系等），但用量都不大。<br /></div><p><img

再結(jié)晶溫度是指經(jīng)過大變形量冷加工的金屬，在1 h的保溫時(shí)間內(nèi)能夠完全再結(jié)晶的溫度。金屬所受變形度越大，所具內(nèi)能越大，則其再結(jié)晶溫度就越底。工業(yè)上再結(jié)晶退火溫度一般要比再結(jié)晶溫度高100～200℃左右，保溫時(shí)間為30～60min?？煞サ脑俳Y(jié)晶溫度大約為700～750℃，因此其再結(jié)晶退火溫度應(yīng)為900～950℃。有資料介紹可伐的再結(jié)晶退火溫度為930℃左右，若單純只為了加工硬化和形變應(yīng)力，則以930℃保溫30～60min即可。但在金屬外殼封接工藝中，可伐與玻璃的實(shí)際燒結(jié)溫度高達(dá)到960℃，為了保證在這一溫度下，能得到更純、含雜質(zhì)更少的可伐材料，一般要求退火溫度不應(yīng)低于燒結(jié)溫度：退火溫度＝燒結(jié)溫度+30～50℃,達(dá)到1000±10℃，高于可伐的再結(jié)晶退火溫度。為了避免過高的溫度引起材料晶體顆粒的二次再結(jié)晶，使晶粒不均勻長大，可以通過縮短保溫時(shí)間來控制?？傊嘶饻囟仍礁?，保溫時(shí)間就相應(yīng)縮短。<br /> 當(dāng)裝爐量大或零件尺寸較大時(shí)，應(yīng)適當(dāng)延遲保溫時(shí)間，此時(shí)退火溫度不應(yīng)太高，防止熱透不均勻，局部晶粒長大。</div><p><img src="http://2024aiimg.qy55.com//cjjhb_soft/86/1136/202402212304575104.jpg"
