鐵鎳合金是一種在弱磁場中具有高磁導(dǎo)率和低矯頑力的低頻軟磁材料。早期鐵鎳合金用于通信，其后采用一種熱處理工藝和真空冶煉的方法使合金特性得到較大的提高。含Ni78%的鐵鎳合金在弱磁場中的磁導(dǎo)率比硅鋼高約10～20倍，普遍用于靈敏繼電器、磁屏蔽、和無線電變壓器、精密的交流和直流儀表、電流互感器（見互感器）中。在鐵鎳合金中加入鉬、錳、鈷、銅、鉻等元素，可得具有更大初始磁導(dǎo)率μi和磁導(dǎo)率μm的三元、四元鐵鎳合金。<br /> 鐵鎳合金具有窄而陡的磁滯回線，在弱磁場中具有很大磁導(dǎo)率和很小的矯頑力,但它的電阻率不大,只適合在1 兆赫以下的頻率范圍工作，否則渦流損耗太大。鐵鎳合金的加工性能好，可制成各種形狀復(fù)雜、尺寸要求的元件。但它的磁性能對機(jī)械應(yīng)力比較敏感，工藝因素對磁性能的影響較大，如沖壓會使μb下降，因而產(chǎn)品性能一致性不易滿足。鐵鎳合金的成本高。常用的鐵鎳合金的特性和用途列于表。<br /></div><p><img

(1)機(jī)械加工應(yīng)力。可伐在冷加工發(fā)生塑性形變時，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)長的時間而不致發(fā)生明顯的變化。若一旦對它加熱，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，就是高溫封接中對鉬組玻璃的拉應(yīng)力，可能會導(dǎo)致玻璃產(chǎn)生微小裂紋而漏氣；<br /> (2)加工硬化。可伐零件在冷加工制造成型的過程中，由于內(nèi)部的材料組織發(fā)生晶粒拉長、晶粒破碎等缺陷，使晶體缺陷大量增加，位錯密度增大。位錯之間距離越小，彼此間干擾越大，每個位錯線都存在一個應(yīng)力場，位錯通過各自應(yīng)力場相互作用，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，位錯之間相互作用的應(yīng)力場將會因晶體的回復(fù)或再結(jié)晶而被打破，失去平衡，這也對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，高溫下會奪氧生成C0，因而會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 /> (5)去除內(nèi)部吸附氣體。<br /> 除上述外，在適當(dāng)?shù)臍夥罩羞M(jìn)行高溫?zé)崽幚恚€具有進(jìn)一步清潔金屬零件的作用。<br /></div><p><img src="http://2024aiimg.qy55.com//cjjhb_soft/86/1136/202402212304400775.jpg"
