5 )铸态azsm合金经200时效3小时、固溶4小时后空冷和炉冷、 400固溶-水淬90时效和自然时效的综合性能较铸态有显著的提高。 - The paper introduced testing principle of infrared image in course of metallurgy heat engineering testing , based on several applied examples , analyzed application properties and range of infrared image technique and thermal image analysis in heat engineering analysis
振动时效技术主要是利用共振消除和均匀金属构件内部残余应力,起到增强结构件抗变形能力、稳定尺寸精度,在很大程度上替代传统的热时效和自然时效工艺,因此大大节省了能耗、降低了成本.文章介绍了振动时效的作用、特点、机理及工艺和发展应用 - The results indicated that , the fabrication process of ultra - fine grain material is mainly determined by the stress , rotate speed and the flux of cooling water . the grain refining and the hardening effect are mostly affected by the rotate speed and the flux of cooling water . compared with commercial ly12 , the invalidate strength and the prolongation rate of the ultra - fine grain material are properly improved in the measurement of compression property ; and the abrupt change of the dilatability 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压扭强变形区转移法可以得到棒状的超细晶材料，轴向压力、扭转速度和温度是采用该方法制备超细晶材料的主控参数；试件的旋转转速和冷却速度对变形区晶粒细化和硬化效果影响显著；超细晶ly12的压缩性能与淬火+自然时效状态的ly12压缩性能相比，断裂强度和延伸率均有一定程度的增强；超细晶ly12的热膨胀系数在550左右发生明显的变化。 - From an examination of the tensile behavior of cz ly12 alloys under different temperature and strain rate , two 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 ductility achieved at high strain rate is generally attributed to the dominant role of gbs accommodating mechanisms , which is considered as dislocation creep within grains controlled by subgrains
研究选用自然时效淬火态的ly12铝合金，进行了一系列不同温度和应变速率下的单轴拉伸试验， 480下，观察到与传统细晶超塑性特征区间相反的行为：较高应变速率下，动态再结晶使晶粒细化，促进了晶界滑移，亚晶界控制的晶内位错蠕变是晶界滑移的主要协调机制。
