The importance of interlayers in diffusion welding - A review
Akca, Enes
Gürsel, Ali
During the last few years diffusion welding has become significant attention regarding its suitable applications in comparison to traditional welding techniques. Bonding of dissimilar materials has always been a challenging task due to poor control on grain size and sensitive mechanical properties that could have been made by joining with traditional welding techniques. Moreover, joining dissimilar materials such as Aluminum/steel, metal/glass, Aluminum/copper had been achieved with the usage of diffusion welding. This work presents a review of literature regarding the importance of diffusion welding and influence of interlayers in diffusion welding. Additionally, this paper provides different examples and applications of diffusion welding. Main advantages of this technique are, clean and undamaged exterior parts of weld, power savings, stable and strong bond, time efficiency.

Green materials, green technology, building, polymer
A green material suits most tunefully within ecosystem practices and donates to the achievement of a service-based economy. Due to the properties of non-toxic, organic and recycling, green materials are widely used in various industrial applications. Green materials can be categorized as natural materials, plastics, ceramics and composite materials, and they are extensively utilized in building materials. In this study, green materials are briefly introduced and their applications are shortly reviewed.

A university emblem die design and molding
Turan, Kemal
Findik, Fehim
To decrease the price of materials is very important. It is possible to make cost effective products by means of method that without machining i.e kitchen appliances, electronic devices and even plastic products. In this study one of the branch of design compression dies are investigated and a university emblem is studied using that kind of die. By compression dies any letters, numbers, figures and patterns can be produced on the metallic sheet. Frequently some problem such as cracking of punches and uniforming of the figures and patterns may be occurred. The advised solutions for those problems are enough compressing force and working materials hardness. Furthermore the hardness of the punch surface should be among 58-64 Hrc.

A review on the matrix toughness of thermoplastic materials
Akca, Enes
Gursel, Ali
Composite material has attracted increasingly remarked interest over the last few decades and set it apart in its own class due to its distinct properties. This paper is a review on the matrix toughness of thermoplastic polymer composites. Toughness of thermoplastics has been actively studied since the 1980s.the main advantage in using thermoplastics to toughen resins is that their incorporation need not result in important decreases in desirable properties such as modules and yield strengths. However, the predominant criteria for achieving optimum toughness enhancement in the thermoplastic toughening of epoxy resins are still not all that clear from the literature. Epoxy and polyester resins are commonly modified by introducing carboxyl-terminated butadiene-acrylonitrile copolymers (ctbn). A tough elastomeric phase, for example, a silicone rubber with good thermal resistance in a polyimide resin, produced a tough matrix material. It summarizes what the authors believe are the important requirements for good thermoplastic toughening.
