(1)機(jī)械加工應(yīng)力?？煞ピ诶浼庸ぐl(fā)生塑性形變時(shí)，約有施加能量的10％～15％轉(zhuǎn)化為內(nèi)能，即所說的內(nèi)應(yīng)力，從而使可伐材料組織處于一種不穩(wěn)定的狀態(tài)中，在室溫下，這種狀態(tài)能維持相當(dāng)長(zhǎng)的時(shí)間而不致發(fā)生明顯的變化。若一旦對(duì)它加熱，將發(fā)生一系列的組織和性能變化，使其材料組織趨向一種穩(wěn)定狀態(tài)，這種組織和性能的變化，特別是組織結(jié)構(gòu)的變化反映在封接面上，就是高溫封接中對(duì)鉬組玻璃的拉應(yīng)力，可能會(huì)導(dǎo)致玻璃產(chǎn)生微小裂紋而漏氣；<br /> (2)加工硬化?？煞チ慵诶浼庸ぶ圃斐尚偷倪^程中，由于內(nèi)部的材料組織發(fā)生晶粒拉長(zhǎng)、晶粒破碎等缺陷，使晶體缺陷大量增加，位錯(cuò)密度增大。位錯(cuò)之間距離越小，彼此間干擾越大，每個(gè)位錯(cuò)線都存在一個(gè)應(yīng)力場(chǎng)，位錯(cuò)通過各自應(yīng)力場(chǎng)相互作用，使可伐的硬度、彈性增加，而塑性下降，也就是加工硬化。加工硬化若不，在高溫封接時(shí)，位錯(cuò)之間相互作用的應(yīng)力場(chǎng)將會(huì)因晶體的回復(fù)或再結(jié)晶而被打破，失去平衡，這也對(duì)金屬與玻璃的封接有一定的應(yīng)力影響；<br /> (3)使材料組織均勻、細(xì)化、穩(wěn)定、一致；<br /> (4)金屬表面脫碳。碳作為一種還原物質(zhì)，具有強(qiáng)烈還原性，高溫下會(huì)奪氧生成C0，因而會(huì)在金屬與玻璃的封接面或玻璃中產(chǎn)生氣泡，不僅降低了金屬與玻璃的封接強(qiáng)度，也嚴(yán)重地影響了玻璃的性能，這在封接工藝中是絕不允許的；<br />

class="khcont">可伐合金毛細(xì)管是指內(nèi)徑很細(xì)的長(zhǎng)條形管子。<br /> Kovar合金又稱封接合金或定膨脹合金。在-70至500℃溫度范圍內(nèi)，具有比較恒定的較低或中等程度膨脹系數(shù)的合金。主要類型有鐵鎳、鐵鎳鈷、鐵鎳鉻系合金。還有無氧銅、鎢、鉬及其合金和復(fù)合材料。主要用于電子工業(yè)及電真空工業(yè)作封接材料。<br /> 可伐合金組織結(jié)構(gòu)<br /> 合金按規(guī)定的熱處理制度處理后，再經(jīng)-78.5℃冷凍，大于等于4h不應(yīng)出現(xiàn)馬氏體組織。但當(dāng)合金成分不當(dāng)時(shí)，在常溫或低溫下將發(fā)生不同程度的奧氏體(γ)向針狀馬氏體(α)轉(zhuǎn)變，相變時(shí)伴隨著體積膨脹效應(yīng)。合金的膨脹系數(shù)相應(yīng)增高，致使封接件的內(nèi)應(yīng)力劇增，甚至造成部分損壞。影響合金低溫組織穩(wěn)定性的主要因素是合金的化學(xué)成分。從Fe-Ni-Co三元相圖中可以看到，鎳是穩(wěn)定γ相的主要元素，鎳含量偏高有利于γ相的穩(wěn)定。隨合金總變形率增加其組織越趨向穩(wěn)定。合金成分偏析也可能造成局部區(qū)域的γ→α相變。此外晶粒粗大也會(huì)促進(jìn)γ→α相變。</div><p><img
