The mechanical properties and microstructure of copper base shape memory alloys are relatively well known, while data on thermal properties (thermal conductivity, specific heat, and temperature conductivity) are not available. In the frame of our investigation work thermal properties of rapidly solidified Cu-Al-Ni-Mn alloy were deter...

Metallic materials in granular packings show different electrical properties from their bulkcounterparts. In this paper, we investigate the temporal evolution of the electrical conductivity ofgranular metals. We use metallic beads arranged in different one-, two- and three-dimensionalensembles through which different constant currents are injected....

The results of the comparative prediction of thermodynamic properties for Ga-Zn-Sn system are presented in this paper. Two thermodynamic predicting models were used for the calculation – one symmetrical (Muggianu), one assymetrical (Toop) model and general solution model. The calculations were done for different sections in exa...

Application of the new materials in the automotive industry is a challenge that is placed in front of researchers of our times. The challenge is reflected in the modification of the chemical composition of steel and heat treatment in order to achieve improved mechanical properties. Steel 17-7PH is austenitic - martensitic steel with ...
