20Mn5 steel is widely used in the manufacture of heavy hydro-generator shaft forging due to its strength, toughness, and wear resistance. However, the hot deformation and recrystallization behaviors of 20Mn5 steel compressed under a high temperature were not studied. For this article, hot compression experiments under temperatures of 850-1200 °C and strain rates of 0.01 s-1-1 s-1 were conducted...

Manganese minerals are widely distributed throughout the globe. The most important industrial uses of Mn are in the manufacture of steel, non-ferrous alloys, carbon-zinc batteries and some chemical reagents. Microbial recovery of manganese from low grade manganese ores using bioleaching was investigated in this paper. A bacterial strain, Staphylococcus epidermidis (MTCC-435) was collected from ...

This paper gives a historical review of Kansei-based media technologies in Japan. Kansei is a Japanese word, the meaning of which covers sensibility, sentiment, emotion, and feeling. Kansei research started in the field of music, because music is the most acceptable of the arts to computer science. In the 1990s, the applications of Kansei machine vision became widespread in many industrial fiel...

With the developments in automobile technologies; more focus is given to the vehicle weight reduction. About 30% weight is contributed by the automobile body. Now-a-days, plastic composites are used to manufacture automobile bodies as they are strong, light, corrosion resistant and easy to use. This paper represents the selection of plastic composites to build vehicle roof as a replacement of c...

Interfacial membranes collected at revision from 11 failed uncemented Ti-alloy total hip replacements were examined. Particles in the membranes were characterised by electron microscopy, microchemical spectroscopy and particle size analysis. Most were polyethylene and had a mean size of 0.53 micron +/- 0.3. They were similar to the particles seen in the base resin used in the manufacture of the...

The nickel-titanium alloy Nitinol has been used in the manufacture of endodontic instruments in recent years. Nitinol alloys have greater strength and a lower modulus of elasticity compared with stainless steel alloys. The super-elastic behaviour of Nitinol wires means that on unloading they return to their original shape following deformation. These properties are of interest in endodontology ...

In the UK, and in many other parts of the world, reinforcing steels are specified to British Standards, or very similar, which in the main do not specify process routes. As a result, many specifiers, purchasers and users are unaware of the different process routes used in their manufacture. Manufacturing process routes for some of the reinforcing steel products used have changed considerably in...

This work presents a novel coating technique to manufacture ceramic superhydrophobic coatings rapidly and economically. A rare earth oxide (REO) was selected as the coating material due to its hydrophobic nature, chemical inertness, high temperature stability, and good mechanical properties, and deposited on stainless steel substrates by solution precursor plasma spray (SPPS). The effects of va...

Here we present a method to manufacture peptide-concentrating MALDI-plates with alkyl ketene dimer (AKD) as a new superhydrophobic coating. The fabrication of the hydrophobic plates included application of AKD by airbrush, and negative contact printing to generate the concentration sites. Deposited sample droplets were contained within the prestructured sites, and self-adjusted onto the site if...
