The use of material that is specified as armor steel has a high resistant value. quenching and tempering process done to improve the toughness material. uses temperature 900oC on with water medium temperatures 125oC 175oC holding time for 30 minutes. tests include impact test determine increase in fractography ductility There decrease value occurs after process. increasing due tampering 32 J du...

Real-time evaluation of materials’ mechanical response is crucial to further improve the performance surfaces and coatings because widely used post-processing techniques (e.g., fractography analysis) cannot provide deep insight into deformation damage mechanisms that occur changes in coatings’ material corresponding dynamic thermomechanical loading conditions. The advanced situ examination meth...

The liquid metal embrittlement sensitivity of a low nickel 316 L austenitic steel has been studied with eutectic gallium indium alloy. case is firmly established this and by X-Ray fractography EBSD. Brittle to ductile recoveries were observed via dedicated parametric study (varying cross-head speed temperature). return ductility temperature strongly correlated significant reduction in plastical...

• Mechanical tests are performed on Al-alloy subjected to irradiation and post- annealing Matrix hardening due causes the decrease of toughness properties Crack instabilities tearing modulus Fractography shows typically ductile fracture mechanisms after Fracture identical in any state: irradiated or not, heat-treated not This study analyses increase crack propagations (pop-in) with during testi...

In order to investigate the fatigue properties of extruded magnesium alloy in very high-cycle regime, rotary bending fatigue test was performed in ambient atmosphere at room temperature using the hourglass shaped specimens of AZ80 alloys extruded (Fspecimen) and treated by an artificial aging after extrusion (T5-specimen). From the experimental results, both specimens show a clear step-wise S-N...

Today, a substantial part of the dental crown production uses computer-aided design and computer-aided manufacturing (CAD/CAM) technology. A recent step in restorative dentistry is the replacement of natural tooth structure with pre-polymerized and machined resin-based methacrylic polymers. Recently, a new CAD/CAM composite was launched for the crown indication in the load-bearing area, but the...

STATEMENT OF PROBLEM Dental resin composites are becoming prevalent in restorative dentistry and have almost replaced amalgam nowadays. Consequently, their mechanical properties and durability are critical. OBJECTIVES The aim of this study was to produce Pyrex glass nano-particles by wet milling process and use them as reinforcement in dental resins for anterior restorations and then examinat...
