The effects of heat treatment on some mechanical properties of laminated black pine (Pinus nigra)
Black pine (Pinus nigra) has high industrial usage potential and large plantation in Turkey. Larch wood was treated with heat to determine its mechanical properties, such as bending strength and pressure and order to determine its adhesion strength. Laminating adhesives are used for the construction of polyvinyl acetate and polyurethane. Heat treatment was applied to the samples at 100-150°C for 4 h in drying oven. In the result of the experiments, heat treated samples give better results due to temperature increase.

Effect of Heat Treatment on Timbers—A Review
Heat treatment is one of the environment-friendly ways to treat timber that will lead to the improvement of timber natural quality and equip the timber with new properties by modifying the timber. It is an eco-friendly and alternative treatment method that will modify the properties of timber by using high temperature instead of using chemical preservatives. This paper presents the overview of heat treatment effects on physical, chemical and mechanical properties in the case of heat treated timbers research. It is learned that at temperature over 150 °C, the physical, mechanical and chemical properties of the wood gradually get altered permanently. The research would be essential for the purpose of finding a better alternative to treat the timber to replace the chemical treatment, Copper Chromium Arsenic (CCA) which is not environment friendly. Research had shown that heat treatment on softwood as internal purpose especially in furniture application, hence there is a need to expand this treatment as an alternative method on hardwood timbers to be used in construction industry.
SR topography of plastically deformed Fe-Si bicrystals - observation in situ and post mortem
SR reflection topography was applied to study the interaction of slip dislocations with the grain boundaries in Fe-4at%Si bicrystals deformed by compression. Three experimental settings with either a white or monochromatic beam were used and the corresponding orientation contrast analysed. Dislocation transmission through the grain boundary was observed in bicrystals with favourable geometry of the slip systems.
