Ti–6Al–4V scaffolds were fabricated by powder metallurgical space holder technique in this research. The most added magnesium (Mg) powder was evaporated and a skeleton of Ti-6Al-4V alloy was produced. For this purpose Ti-6Al-4V and Mg powders mixture compacted in a steel die by applying uniaxial pressure of 500 MPa before sintering the green product in a sealed quartz tubes at 900 °C for 2 hour...

It is shown that the existence of a BIB design with parameters v = 2k − 2k+1, b = 2v, r = 2k, k, λ = 1 implies the existence of Hadamard matrices of orders 4v and 8vt, where t is an integer for which an orthogonal design of order 4t and type (t, t, t, t) exists.

OBJECTIVE The purpose of this study was to determine the microtensile bond strength of various resin composite/adhesive systems to alumina particle abraded Ti-6Al-4V substrate after aging for 24h, 10 days, and 30 days in distilled water at 37 degrees C. METHODS Four laboratory resin composite veneering systems (Gradia, GR; Solidex, SOL; Ceramage, CER; and Sinfony, SF) were bonded to 25 mm dia...

34 Nesfatin-1, a novel hypothalamic peptide, inhibits nocturnal feeding behavior and 35 gastrointestinal motility in rodents. The effects of nesfatin-1 on gastrointestinal secretory 36 function, including gastric acid production, have not been evaluated. Nesfatin-1 was injected 37 into the 4 intracerebral ventricle (4V) of chronically cannulated rats to identify a nesfatin dose 38 sufficient to...

Cutting tool wear during drilling operations can cause damage to cutting tools, machine and workpieces which should be analyzed minimized. impacts not just life but also the quality of final product in terms dimensional accuracy surface integrity. High mechanical thermal loads are generated difficult-to-cut materials such as Ti-6Al-4V alloy reduce chip formation process. Thus, increase drilled ...

Abstract The fraction and size of pores present in EBM Ti-6Al-4V specimens varies depending on the melting strategy used, whether linear raster or point melting.

A novel two-step bonding of Ti-6Al-4V/Si 3 N 4 joint was developed with Nb interlayer as residual-stress reliever via low-pressure transient-liquid-phase (TLPB) Ti-6Al-4V/Nb side prior to active-metal brazing Nb/Si side. While 1.75 mass% Ti in a 50-µm-thick CUSIL-ABA® filler sufficient for sound at when brazed 1103 K 10 min, one-step-brazed joints area × mm 2 were prone failure the due brittle ...
