Strength properties of the low-melting-point alloys

Wierzbicki Ł.

Journal of Achievements in Materials and Manufacturing Engineering

2014

Vol. 67, nr 1

26--31

Purpose: The aim of this paper was to determine the strength and elasticity of low melting point alloys. In particular, the laboratory tests were observed to check the shape of the compression curve. This is a result of recrystallization. Design/methodology/approach: The strength and stiffness of the low melting point alloys was found. The unusual shape of the compression curve was observed. In order to determine if it is the result of crystallization, the samples were cooled in the liquid nitrogen. In the next step another attempt will be perform to the compression. Findings: The results of the compression tests and their analysis are presented. Research limitations/implications: Presented research was limited to alloys in the form of small samples. The developed technology of this type of preparation of this type alloys is limited to small volumes because the melts are small and expensive. Practical implications: The low melting point alloys have many possible applications. First of all they are materials with higher thermal conductivity and electrical conductivity. Conducted research programme showed that these materials exhibit also good the mechanical properties. Originality/value: Carrying out of the experiment that explaining of the shape of the compression curve for low-melting-points alloys. This experiment may be have a high educational value for the study. This experiment can have high an educational value for the science.
