The optimisation of heat treatment parameters for Al—Cu— Mg—Ag cast alloys 2xxx having different microstructural scales was investigated. Thermo-Calc software was used to design optimal alloy compositions. Differential scanning calorimetry DSC , scanning electron microscopy and wavelength-dispersive spectroscopy technique were employed to determine proper solution heat treatment temperature and homogenisation time as well as incidence of incipient melting. Proper artificial ageing temperature for each alloy was identified using DSC analysis and hardness measurement. Addition of Mg to Al—Cu alloys promoted the formation of phases having a rather low melting temperature which demands multi-step solution treatment.

Aluminium Alloys and Composites. Aluminum is a metal of great importance because of its excellent corrosion resistance, high electrical and thermal conductivity, good reflectivity and very good recycling characteristics. There are nine different series of aluminum, which will be discussed later in this section, four of which are referred to as heat-treatable aluminum alloys, and these alloys are so-called because of the potential to increase the mechanical properties by precipitation strengthening [ 1 , 2 ]. The properties of heat treatable Al-alloys can be further enhanced by the inclusion of a reinforcing phase that increases the mechanical properties of the overall composite. Metal matrix composites MMC are usually manmade materials that consist of two or more distinct phases; a continuous metallic phase the matrix and a secondary reinforcing phase.


Around 85% is being used in the form of wrought products, which replace the use of cast iron. Further, the major features of aluminium alloy are.

Aluminium alloys or aluminum alloys ; see spelling differences are alloys in which aluminium Al is the predominant metal. The typical alloying elements are copper , magnesium , manganese , silicon , tin and zinc. There are two principal classifications, namely casting alloys and wrought alloys, both of which are further subdivided into the categories heat-treatable and non-heat-treatable.

Wear mechanisms experienced by an automotive grade Al-Si-Cu alloy under sliding conditions. Diego E. Lozano 1 , Rafael. Juarez-Hernandez 1 M. The wear mechanisms experienced by a cast hypereutectic Al-Si-Cu alloy were studied using a pin on disc tribometer, under lubricated sliding conditions at different normal loads.

Despite decades of extensive research and application, commercial aluminum alloys are still poorly understood in terms of the phase composition and phase transformations occurring during solidification, cooling, and heating. Multicomponent Phase Diagrams: Applications for Commercial Aluminum Alloys aims to apply multi-component phase diagrams to commercial aluminum alloys, and give a comprehensive coverage of available and assessed phase diagrams for aluminum-based alloy systems of different dimensionality.

Introduction

Он почувствовал боль в ногах и сбавил скорость. Дальше бежать было некуда. Как трасса, на продолжение которой не хватило денег, улочка вдруг оборвалась. Перед ним была высокая стена, деревянная скамья и больше. Он посмотрел вверх, на крышу трехэтажного дома, развернулся и бросился назад, но почти тут же остановился. В некотором отдалении от него возникла фигура человека, приближавшегося медленно и неотвратимо.

Как они этого сразу не заметили. Северная Дакота - вовсе не отсылка к названию американского штата, это соль, которой он посыпал их раны. Он даже предупредил АНБ, подбросив ключ, что NDAKOTA - он. Это имя так просто превращается в Танкадо. И лучшие в мире специалисты-криптографы этого не поняли, прошли мимо, на что он и рассчитывал.

 - Вы обещали, что они будут у меня сегодня до конца дня. - Произошло нечто непредвиденное. - Танкадо мертв. - Да, - сказал голос.  - Мой человек ликвидировал его, но не получил ключ. За секунду до смерти Танкадо успел отдать его какому-то туристу. - Это возмутительно! - взорвался Нуматака.
