Research of hydrogen diffusion in VT6 alloy is carried out considering different types of heat treating and hydrogen charging. The influence of microalloying on the susceptibility to hydride formation and embrittlement of titanium alloys is analyzed, and also effects of an oxide film on hydrogen charging during heat treatment without protective atmosphere, are studied.

The present work is enhancement of near surface characteristics for hybrid fiber reinforced concrete (aspect ratio 40+100). Here in this research work an attempt has made to study water absorption values for different types of fiber reinforced concrete, which are having different aspect ratios like 40, 100 and 40+100. Concrete mix along with fibers are casted and cured for 28days. Both water absorption test and sorptivity tests carried on hardened concrete. The main objective is to check variation in absorption values due to addition of different types of fibers. Here totally five different types of fibers are considered like steel fiber, Galvanized iron fibres, High density polyethylene fibres, waste plastic fiber and polypropylene fibers Experimental investigation shows that except polyprolene hybrid mix concrete other hybrid mixes has showed good results. But as compared to mono fiber reinforced concrete hybrid fiber reinforced concrete has showed better results. This research was aimed to provide benchmark for future research works on near surface characteristics of hybrid fiber reinforced concrete.

Scaffolds, three-dimensional (3D) substrates providing appropriate mechanical support and biological environments for new tissue formation, are the most common approaches in tissue engineering. To improve scaffold properties such as mechanical properties, surface characteristics, biocompatibility and biodegradability, different types of fillers have been used reinforcing biocompatible and biodegradable polymers. This paper investigates and compares the mechanical and biological behaviors of 3D printed poly(ε-caprolactone) scaffolds reinforced with graphene (G) and graphene oxide (GO) at different concentrations. Results show that contrary to G which improves mechanical properties and enhances cell attachment and proliferation, GO seems to show some cytotoxicity, particular at high contents.

Carbon fiber (CF) reinforced compositesusing different types of vinylester (VE)resin includingconventional VE resinhave been prepared. The mechanical performance were characterized by different tests, such as tensile, mode-I interlaminarfracture toughness, tension-tension fatigue and scanning electron microscope (SEM).The experimental results showed that the tensile strength of CF/VE composites changed at a wide range from 22.3% to 37.8% in comparison with the CF/conventional VE composite due to resin type, where the strain at failure was varying. The tensile strength increased with an increase of adhesive strength between carbon fiber and VE resin characterized by the microdroplet test. Namely, a good correlation between the tensile strength of composites and the adhesive strength was found. On the other hand, almost an inverse correlation was found between the tensile strength of composites and the interlaminar fracture toughness of composites obtained by DCB (double cantilever beams) tests. There was no apparent correlation found between the strain at failure for pure resins and the tensile strength of composites.Thefatigue life of CF/VE compositesincreased as well as the tensile strength with an increase of the adhesive strength between carbon fiber and the resin. The samples sometime survived 1000 times longer than that of CF/conventional VE compositewhen the maximum cycle stress was 70% of the tensile strength of the strongest composite.
