INFLUENCE OF THE Al CONTENT ON THE PHASE TRANSFORMATIONS IN Cu-Al-Ag ALLOYS
The literature about alloys of the Cu-Al system is extensive, due to its practical use. These alloys are of low cost and present good strength and hardness, depending on the Al content. They are used for making sleeves, guides, seats, flanges, gear wheels and many other critical small parts, as electrolysis cell cathodes, circuit plates and casting moulds when high thermal conductivity is neede...
متن کاملPRECIPITATION STRENGTHENING BEHAVIOR OF Al-Cu-Mn ALLOYS WITH THE EFFECT OF CASTING SEGREGATION
Al-Cu-Mn is one of typical heat-treatable cast alloys with high strength which has been widely used in aerospace and automobile industries. The complete manufacturing process for AlCu-Mn components includes low pressure die casting, T6 heat treatment and machining. It has been found that the property in former process has been transferred to the sequent step with considerable effect. In this pa...
متن کاملMagnetoelasticity and Magnetoresistance in Cu–Al–Mn Shape-Memory Alloys
This paper is aimed at studying the effect of a magnetic field on the martensitic transition of a Cu–Al–Mn shape-memory alloy. The martensitic transition has been studied through resistance measurements under applied magnetic fields ranging from 0 to 50 kOe. Negative magnetoresistance showing an almost linear dependence with the square of the magnetization has been observed. This magnetoresisti...
متن کاملInfluence of Natural Aging Time on Two-Step Aging Behavior of Al-Mg-Si(-Cu) Alloys
Nanoclusters formed during natural aging cause the negative effect of the two-step aging in the age-hardenable Al-Mg-Si alloys. The relationship between the clustering behavior during natural aging and the two-step aging behavior was studied using the hardness, differential scanning calorimetry (DSC), electrical resistivity measurements, transmission electron microscopy (TEM) observation in the...
متن کاملthe influence of the neo-platonic concept of poetic imagination on wordsworth’s poetry
بر اساس نظریه افلاطون در باره شعر خلاقیت هنری مورد انتقاد قرار گرفته است. نظریه کلی در مورد شعر این بود که شعر از ظواهرتقلید میکند و نه حقیقت. چون سایه ای از حقیقت است. اما با پیدایش فلسفه نو افلاطونی، انتقاتات قبلی در مورد شعر و شاعری اصلاح شد. فلوطین در کتاب انئید، اساس خلق هنری را بر محور مُثل افلاطونی قرار داد. وی باور داشت که هنر مندان در خلق آثار هنری، تحت تاثیر مُثل افلاطونی بوده و عوالمی ...
