Al-based alloys have a long tradition of use especially as a lightweight material for traffic systems. The limits of conventional casting have not yet been reached. One of the recent aims in the research of Al-based alloys is to realize the potential of non-traditional alloying elements such as transitions metals (TM) – e.g. Sc, Zr, Mn, Cr, etc. and their combinations. In this contribution we d...

Velocity of sound and thermal expansion measurements on Cr-Pt alloys in the concentration range up to 1.5 at.% Pt are reported. The existence of a triple point and a mixed magnetic state on the magnetic phase diagram is suggested. The magnetic phase diagram [I] of dilute Cr-Pt alloys contains a paramagnetic (P), an incommensurate (I) and a commensurate (C) spin density wave (SDW) phase. Rather ...

There is a wide variety of dental alloys, ranging from nearly pure gold and conventional gold-based alloys to alloys based on silver, palladium, nickel, cobalt, iron, titanium, tin, and other metals (Table 1). The types of dental alloys have increased significantly since 1980s in order to change the market price of gold and palladium. Although gold alloys are the mate‐ rials of choice in this a...

60) to be used for fabricating jewellery, so alloying additions are made to increase the hardness. Platinum jewellery alloys usually have platinum contents of 90 wt.% and higher. The most common alloys are hallmarked as 950 platinum (95 wt.%). Unlike carat gold (Au) jewellery alloys, where relatively large additions can be made (to alter the properties of the alloy such as its hardness or colou...

Background and Aims: Poor adhesion between porcelain and some of the dental alloys is one of the most challenges to select the desirable alloy in dental restorations. Therefore, the aim of this study was to evaluate the bond strength of porcelain to some of the commercial alloys. This can help in selection of desirable alloy. Materials and Methods: The shear bond strength of porcelain to the t...

We have investigated the effect of pressure and thermal ageing on transformation behavior of Ni-%45.16Ti shape memory alloy. 70-320 MPa pressure was applied and annealed at 500 o C for 2 hour to see the effect of applied pressure on transformation temperature. It was observed that the starting and final temperature of austenit increased, the martensite start temperature almost remain constant a...

AIMS To compare silver and copper, metals with known antimicrobial properties, by evaluating the effects of temperature and humidity on efficacy by challenging with methicillin resistant Staphylococcus aureus (MRSA). METHODS AND RESULTS Using standard methodology described in a globally used Japanese Industrial Standard, JIS Z 2801, a silver ion-containing material exhibited >5 log reduction ...

Employing first-principles calculations we study the structural, electronic and magnetic properties of the [Sc1−xVx]C and [Sc1−xVx]Si alloys. In their equilibrium rocksalt structure all alloys are non-magnetic. The zincblende and wurtzite structures are degenerated with respect to the total energy. For all concentrations the alloys in these lattice structures are half-metallic with the gap loca...

The influence of nitrogen (0 to 0.27 wtYo) on martensite formation in an experimental low-nickel stainless-steel alloy (Fe-17Cr-7Mn-4Ni) has been investigated. The alloys containing 0.1 wtYo or more nitrogen are fully austenitic at room temperature; those containing less nitrogen consist of a mixture of austenite, martensite and S-ferrite. The alloys containing less than 0.2 wtYo nitrogen are m...
