Microstructure, mechanical properties, wear resistance, corrosion and corrosive resistance of AlCrFeNiWx (x = 0, 0.1, 0.2, 0.3 0.4) medium-entropy alloys (MEAs) prepared by vacuum arc melting process were investigated. Results the study show that microstructure as-cast is composed one disordered Fe-Cr rich BCC phase (A2) ordered NiAl-rich (B2) when x 0 0.1; W particles appear ≥ 0.2. Hardness st...

This paper takes a closer look at behavioral subtyping in the context of concurrency, by considering an example of subtyping of a concurrent datastructure taken from sensor networks. Akin to the extension of a state-machine, this example illustrates conflicts caused by the interference of concurrency and inheritance. In short, the extension consists in declaring additional fields in a subclass,...

The use of heavier trucks demanded upgrading of a twenty-seven year old bridge in Winnipeg, Manitoba, Canada. Analysis of the precast prestressed concrete girders using the current AASHTO Code indicates a deficiency in the shear capacity. Shear strengthening using Carbon Fibre Reinforced Polymer (CFRP) sheets provides a low-cost solution by increasing the speed of construction and reducing traf...

Using Ni60 alloy, C, TiN and Mo mixed powders as the precursor materials, in situ synthesized Ti(C,N) particles reinforcing Ni-based composite coatings are produced on Ti6Al4V alloys by laser cladding. Phase constituents, microstructures and wear properties of the composite coatings with 0 wt % Mo, 4 wt % Mo and 8 wt % Mo additions are studied comparatively. Results indicate that Ti(C,N) is for...
