PRECIPITATION 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 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 ...
Drawing CCCT Diagrams and Investigation of Deformation Effects on Martensite and Bainite Trabsformations in NiCrMoV Steel
In this study, two CCCT diagrams are drawn to be compared with a CCT diagram. The CCCT diagrams represent continuous cooling transformations in stress assisted state. The increased Md and Bd temperatures of CCCT diagrams were also compared with those of the CCT diagrams and the cause was investigated from both thermodynamic and metallurgical viewpoints. Thermodynamic examinations revealed that ...
متن کاملA Model for Precipitation Kinetics and Strengthening in Al-Cu-Mg Alloys
A physically-based numerical model is developed to predict the microstructural evolution and strengthening in Al-Cu-Mg alloys during isothermal treatments. The modelling of the formation kinetics of the precipitates is based on the Kampmann and Wagner model. The strengthening by the shearable Cu:Mg co-clusters is modelled on the basis of modulus strengthening mechanism and the strengthening by ...
متن کاملThe Precipitation of Carbides during Tempering of High Carbon Martensite*
perature range between 260° and 360°C. Jack showed that thin platelets of cementite formed at the beginning of this stage(10). In high carbon steels, the transformation twin interfaces are potent nucleation sites for the cementite formation and the cementite is related to the ferrite by Bagaryatskii's orientation relationship(2)(3)(11). Although there is no direct evidence of its existence in s...
