Metal composite materials have found application in many areas of daily life for quite some time. Often it is not realized that the application makes use of composite materials. These materials are produced in situ from the conventional production and processing of metals. Here, the Dalmatian sword with its meander structure, which results from welding two types of steel by repeated forging, ca...

Aluminum based metal matrix composites (MMCs) have received considerable attention in the automotive, aerospace and nuclear industries. One of the main challenges using Al-based MMCs is the influence of the reinforcement particles on the corrosion resistance. In the present study, the corrosion behavior of Al-B₄C MMCs in a 3.5 wt.% NaCl solution were investigated using potentiodynamic polarizat...

Introduction – Shrinkage during polymerization of resin-based composite materials may lead to gap formation and hamper the marginal adaptation of the restorations. To reduce the problem of polymerization shrinkage, a new composite material (FiltekTM Silorane, 3M-ESPE, Germany), with a reduced shrinkage, has been marketed. Objective – To investigate whether reduced polymerization shrinkage impro...

EDM is a prominent non-traditional machining process, which is widely used for machining hard materials which is not possible byconventional processes. A very special aspect of this process is a surface modificationby material transfer from the tool electrode to the work-piece which is commonly known as electro discharge coating (EDC). In this work, electrode prepared with tungsten (W) and copp...

A numerical scheme is presented to compute the response of a composite material to an applied eld. The scheme is based on an iteration that uses a Fourier transform based projection method to compute the response of a reference material to the applied eld, and a contraction mapping to relate the response of the reference material to the response of the composite material. The scheme also utiliz...

The results of a study mixing compositions based on polypropylene and vegetable fillers modified with an enzyme preparation are presented. During the experiment, optimal modification time ratio volume water to mass filler during were determined. Physical mechanical tests revealed that composites superior basic without modification.

Microwave absorbing materials (MAMs) are widely researched due to their use in many practical applications including both civil and defense sectors. Irrespective of the humongous efforts various researchers, development a wide bandwidth, thin coating thickness, low-cost microwave absorber is still challenging task. The existing have not been able meet all specifications together at once require...
