Metal matrix composite materials can be produced by powder metallurgy method. In this study, material with Al+12wt%Si was (P/M) mixed adding 5wt%, 10wt% and 15wt% Cr2O3 powder. + mixture powders were pressed unidirectional 500MPa pressure in a cylindrical mold sintered at 500 ºC. After sintering, optical microstructure, Scanning Electron Microscope (SEM), Energy Dispersive Spectrometer (EDS) mi...

Shiramizu K; Lovric V; Leung AMD; +Walsh WR Surgical & Orthopaedic Research Laboratories, University of New South Wales, Sydney, Australia [email protected] INTRODUCTION Deep infection after total joint replacement is a severe complication, and the use of antibiotic-loaded bone cement as a joint spacer is an established and efficient treatment method to treat infected arthroplasties. When pre...

Abstract Injection molding is a cyclic process comprising of cooling phase as the largest part this cycle. Providing efficient in lesser cycle times significant importance industry. Conformal proven technique for reduction injection molding. In study, we have replaced conventional circuit with an optimized conformal tool (mold). The required heat transfer rate, coolant flow rate and diameter ch...

In this study, we investigated the effect of savory (Satureja hortensis) essential oil, garlic(Allium sativum) powder, and garlic aqueous extract on fungal load of poultry feed. Tothis end, savory essential oil and garlic aqueous extract each amounting 62.5, 125, and250 μl/ml and mg/ml, respectively, per kilogram of feed and garlic powder amounting2.5, 5, and 10 g/kg of feed were used. One and ...

Electromagnetic braking (EMBr) technology, as one of the most effective technologies in continuous casting process, provides an tool for improving internal and external defects steel products. Specifically, EMBr technology takes benefit generation Lorentz force to decrease flow instability, mold powder entrapment, surface defects, if applied properly. For this purpose, gain a clear understandin...

Fluid flow in the mold region of the continuous casting process is responsible for surface defects, slag entrainment, and other steel quality problems. Thus, it is very important to choose nozzle geometries and operating conditions that produce flow patterns within an operating window that avoids these problems. Operating conditions which control mold flow problems include the mold cross sectio...
