aluminum base composite materials with variable properties which have been strengthened by alb 2 particles have been widely used. in this study, composites with variable properties of al-5%b and al-2%mg-2%b which are produced through centrifugal casting are investigated as far as their microstructure and hardness are concerned. the microstructure of these composite were studied by using metallo...

the current study assesses the root causes of hydrogen blisters on low strength carbon steel equipment. for this purpose, some experiments including hardness test, non-destructive test (ndt), metallography, and fractograpghy are conducted. the microstructure of two blisters is assessed by means of optical microscopy and scanning electron microscopy (sem). the microstructural studies show that t...

Pipelines are important in geothermal and most of the pipe materials carbon steel insulated. Pipe insulation that is often used general prone to wetness, heat loss, corrosion. Corrosion a problem especially Under Insulation (CUI). This corrosion results pipeline leakage. The selection nano-tech way overcome CUI extend service life usage. study JIS S45C 1×1 cm insulated with nanotechnology by dr...

Abstract The isostructural series (Ga,In)Pd 2 and (In,Sn)Pd have been established characterised. Together with the recently discovered (Ga,Sn)Pd , they form a triangle along edges of which electronic, structural combination thereof on chemical physical properties can be explored, e. g. in heterogeneous catalysis. Single‐phase ternary samples Ga 1‐ x In Pd Sn are synthesised =0.1 substitution st...

The non-Cu critical current density of Nb3Sn strands has been pushed towards 3000 A/mm2 (12 T, 4.2 K) by increasing the Sn content and reducing the interfilamentary Cu. We compare the susceptibility to A15 filament breakage (under 0.5% bend strain) of the new high-Jc internal Sn conductor geometries with both high-Jc Powder-in-Tube (PIT) and low hysteresis loss distributed filament ITER designs...

Assessment of ERBB2 (HER2) status in breast carcinomas has become critical in determining response to the humanised monoclonal antibody trastuzumab. The current joint College of American Pathologists and the American Society of Clinical Oncology guidelines for the evaluation of HER2 status in breast carcinoma involve testing by immunohistochemistry and fluorescence in situ hybridisation (FISH)....
