Main text This report describes a EURAMET supplementary comparison in Brinell hardness scales of three national metrology institutes Italy, Turkey and Germany; INRiM, UME PTB, respectively. The pilot laboratory is INRiM the where two sets reference blocks for Hardness HBW1/30 HBW2.5/187.5 were used. Each set consists levels used each scales. was realized as planned Technical Protocol with some ...

Attempts have been made to describe the influence of the production process parameters and additions of iron powders on properties of copper infiltrated HSS based composites. The powder compositions used to produce skeletons for further infiltration were: M3/2, M3/2+20% Fe and M3/2+50% Fe. The powders were cold pressed at 800 MPa. The infiltration process was carried out in vacuum. Both green c...

Abstract In our research work, we analyzed the mechanical properties of 3D-printed metallic specimens aluminium bronze material. evaluation, had five groups specimens, manufactured at different laser scanning speeds. total, 25 for which examined various parameters like ultimate tensile strength, engineering yield point, relative strain, and hardness. Results showed that prepared with a lower sp...

Steels with desired properties are essential and always required by many industries. This paper highlights some heat treatment operations various cooling media to achieve different rapid rates. was carried out heating samples of low carbon steel a specific temperature then them rapidly in 8 quenching order obtain microstructure steel. These heat-treated were tested mechanically using the Brinel...

In this research work, Al 1wt% silver coated multi wall carbon nanotube (MWCNT) composite have been processed using powder metallurgy technique. In order to distribute CNT uniformly in the aluminum matrix high energy ball milling is required. . It was found that excessive milling can lead to carbide and alumina formation. So to reduce the milling time, the surface of CNT is modified by coating ...

The aim of this study is to determine some physical and mechanical properties of Paulownia tomentosa wood grown in Turkey. The samples trees harvested from Kargi in Corum. Physical properties including air-dry density oven-dry density basic density swelling, shrinkage and oven-dry and air-dry thermal conductivity coefficients; mechanical properties including bending strength, modulus of elastic...

For the purpose of finding new uses for Miscanthus sinensis var. purpurascens, this study first constructed boards with particles plant and impregnated them phenolic resin at impregnation rates 30 ± 2%, 40 50 60 2%. The were then carbonized carbonization temperature 800℃, after which their density mechanical properties examined according to different rates. results showed that density, flexural...

Tantalum Carbide (TaC) reinforcement was made to lamellar graphite (gray) cast irons that were produced in the physical conditions of a foundry at ratios 0%, 0.025%, 0.155%, and 0.285%. Samples complying with standards prepared using TaC-reinforced iron alloys produced, Brinell hardness tests, compressive strength microstructural analyses conducted. According test results, highest average value...

Cu–Cr–Zr alloys reinforced in situ with TiCx nanoparticles were prepared via combustion synthesis and electromagnetic stirring casting. The microstructure of TiCx/Cu-Cr-Zr composites various contents was analyzed. microhardness Brinell hardness the determined; average volumetric abrasive wear rate worn surface investigated; electrical, thermal conductivity expansion coefficients materials discu...
