(Cr-depletion Zone)，而導(dǎo)致此區(qū)耐蝕性降低，稱為敏化而容易導(dǎo)致沿晶侵蝕(IGA)及沿晶應(yīng)力腐蝕破裂(IGSCC)的發(fā)生。另一方面，沃斯田鐵系析出強化鎳基合金之熱處理則包括 (1)升溫至析出物回溶之溫度之固溶階段以及(2)于γ/ γ'兩相區(qū)持溫之時效階段。其中固溶使得析出物回溶，基地中 γ' 析出所需元素增加，并達成各添加元素之均質(zhì)化，且控制基材 γ 相之晶粒尺寸；而時效階段則可以持溫溫度、時間、冷速與多階段時效來控制 γ' 之體積分率、形貌、尺寸與分布，主要析出物之分布與形貌可影響潛變與耐蝕性質(zhì)。一般而言，強化相常為奈米尺度，以一般金相方法觀察不易。常須藉助倍率較高之穿透式電子顯微鏡(TEM)來掌握析出物形貌。</p><p> 鎳基合金之生產(chǎn)技術(shù) </p> <p> 傳統(tǒng)之鎳基合金的生產(chǎn)流程為鎳原料→ 鎳合金鑄錠(熔煉)→二次精煉→加工→成品→下游應(yīng)用 </p> <p> 一般鎳基合金生產(chǎn)之流程圖 </p> <p>

鎳基合金之成分組成以Ni-Cr-Fe為主，其它元素的添加如Cu、Si、Mn、Al、Ti、Nb、W、C等。一般從文獻可了解這些元素對超合金材料的影響，但若要重組或添加新的合金成份，并了解其在微組織之交互作用，近來已有以材料性質(zhì)模擬軟件，可進行合金系統(tǒng)熱力學(xué)與動力學(xué)的計算，協(xié)助提供高性價比之方向，可提高合金設(shè)計的效率。 </p> <p>
