Ti3 AL-Nb-Mo composites were prepared by sHs using initial powder mixtures of Ti-Al-Nb-Mo and their corrosion and mechanical properties were studied to develop bioand environmental materials. The composites reached 99.8% of theoretical density after the direct consolidation. The composites shows equiaxed primary a2 in a matrix of fine secondary a2 plates and ordered 82 (Bo) forming a basket weave structure. The strain rate sensitivity (m = dlnσ/dlne) at 2% strain is 0.008. Corrosion potential and corrosion rate of the composites formed by sHs were -151. 5m VsHE and 5. 72× 10^(-8)A/cm2 for Ti3 Al-10Nb-1. 5Mo and - 138.4m VsHE and 4. 12×10^(-8)cm2 for Ti3 Al-12Nb-1.5Mo in a 50% NaOH-10%FeCi3 solution, respectively. Corrosion resistance decreased with niobium content in the composites and chloride content in the aqueous solution. selective corrosion of a2 phase in a matrix occurred in the corrosion environment which suggests that the corrosion potential and rate changes are related to the niobium content and Q2 phase in a matrix.

spinel magnetite FeO nanoparticles were synthesized using rambutan peel waste extract as a green ligation and chelating agent. The green synthesized nanoparticles were characterized employing X-ray diffraction(XRD), Raman spectroscopy, FTiR spectroscopy and transmission electron microscopy(TEM) studies. The XRD study revealed spinel phase hda a magnetite structure. The formation of iron oxide nanoparticles using rambutan extract was confirmed employing iR studies. XRD, FTiR and Raman spectrum analyses all supports the synthesis of FeO nanoparticles. The TEM revealed the spinel morphology of the biosynthesized nanoparticles with 200 nm.
