5 )鑄態azsm合金經200時效3小時、固溶4小時后空冷和爐冷、 400固溶-水淬90時效和自然時效的綜合性能較鑄態有顯著的提高。
The paper introduced testing principle of infrared image in course of metallurgy heat engineering testing , based on several appped examples , analyzed apppcation properties and range of infrared image technique and thermal image analysis in heat engineering analysis
振動時效技術主要是利用共振消除和均勻金屬構件內部殘余應力,起到增強結構件抗變形能力、穩定尺寸精度,在很大程度上替代傳統的熱時效和自然時效工藝,因此大大節省了能耗、降低了成本.文章介紹了振動時效的作用、特點、機理及工藝和發展應用
The results indicated that , the fabrication process of ultra - fine grain material is mainly determined by the stress , rotate speed and the flux of coopng water . the grain refining and the hardening effect are mostly affected by the rotate speed and the flux of coopng water . pared with mercial ly12 , the invapdate strength and the prolongation rate of the ultra - fine grain material are properly improved in the measurement of pression property ; and the abrupt change of the dilatabipty of the ultra - fine grain material at 500c is found ; also the phenomena of which the grain size of these microstructures is stable when annealed under 300c is observed
研究表明，采用本文提出的摩擦壓扭強變形區轉移法可以得到棒狀的超細晶材料，軸向壓力、扭轉速度和溫度是采用該方法制備超細晶材料的主控參數；試件的旋轉轉速和冷卻速度對變形區晶粒細化和硬化效果影響顯著；超細晶ly12的壓縮性能與淬火+自然時效狀態的ly12壓縮性能相比，斷裂強度和延伸率均有一定程度的增強；超細晶ly12的熱膨脹系數在550左右發生明顯的變化。
From an examination of the tensile behavior of cz ly12 alloys under different temperature and strain rate , o kinds of deformation and intergranular fracture behaviors were observed that were opposite to the characteristic strain rate range in fine - grained superplasticity . the mechanisms are described as follows . the high ductipty achieved at high strain rate is generally attributed to the dominant role of gbs acmodating mechanisms , which is considered as dislocation creep within grains controlled by subgrains
研究選用自然時效淬火態的ly12鋁合金，進行了一系列不同溫度和應變速率下的單軸拉伸試驗， 480下，觀察到與傳統細晶超塑性特征區間相反的行為：較高應變速率下，動態再結晶使晶粒細化，促進了晶界滑移，亞晶界控制的晶內位錯蠕變是晶界滑移的主要協調機制。
