Silicon Chips
In electronics, an integrated circuit (also known as IC, microcircuit, microchip, silicon chip, or chip) is a miniaturized electronic circuit (consisting mainly of semiconductor devices, as well as passive components) that has been manufactured in the surface of a thin substrate of semiconductor material. Integrated circuits are used in almost all electronic equipment in use today and have revolutionized the world of electronics. This can be prepared by applying different metallurgical techniques. Different Silicon chips are shown in figure.
Computer Hard Disk
A computer hard disk drive reliably stores and retrieves computer data on nano scale regions of the disk. Most of the drive and its components are made of metal. So in this case the computer is depending on metallurgy. It is shown in figure.
Key Board & Mouse
Structure of the key board is mostly made of ceramic materials. Moreover cover of Monitor has a great part of ceramics. The buttons of key board have polymeric character. The ball of mouse is made cast iron, which is another blessing of metallurgy.
Statistical Data on Installed Control Computers; Areas of Their Use. Control computers are widely used in metallurgy, power engineering, and the chemical industry. In recent years there has been a great increase in the number of control computers installed in the metallurgical industry of capitalistic countries. Whereas in 1963, 55 control computers had been installed, at the end of 1965 they numbered 144, and at the beginning of 1967, 260. In terms of the number of control computers,metallurgy is inferior to power engineering and the chemical industry. The number of control computers in the metallurgical industry amounts to about 18% of the totai number of compu- ters installed in various branches of industry of capitalistic countries, which by the beginning of 1967 amounted to 1571 units. More than hatf of the control computers are in the USA, England is in second place, and France is in third place.
Charpy Impact Testing Machine
This tester is used to determine the energy required to break plastics, composites, and metallic materials. Anotch is made at the center of a rectangular standard test specimen, both ends are used as supports. Impact force is applied by releasing the pendulum. The energy required to break a specimen is calculatted by the angle which the specimen swings up corresponding to the residual energy. Here all calculation are done with the help of Computers which are embedded in this machine. It is shown in figure.
In Computer Modeling of Powder Metallurgy Processes In the progressed countries Metallurgical & Mechanical engineers use computer on the practical application of Powder modeling as well as information about interesting developments in the powder technologies: fast field activated sintering, self-propagating high-temperature synthesis, HIP technology for production of large discs for high-performance gas-turbine engines and processing of functionally graded materials.
In Chemical & Extractive Metallurgy
Complex chemical equilibria calculations with the thermodata system, the thermodynamics workbench. Computations using MTDATA of metal-matte-slag-gas equilibria, energy requirements for the hydrogen gas production from decomposition to heated asbestos tailings. Heat and mass transfer simulations on a personal computer. Heat transfer tutor and caster for educational computing and simulation. Modelling made easy: the synthetic intelligence (SI) approach. Expert systems as a process operator assistance tool. The use of computer models in an integrated approach to plant design, process optimization and process control.
In Foundry Industry
Now a days foundry men are using different computer software to improve the properties of their product.
