Question

What is the reason to increase the eutectic points?

Answer 1

A eutectic system (/juːˈtɛktɪk/ yoo-TEK-tik) from the Greek "ευ" (eu = easy) and "τήξις" (teksis = melting) is a homogeneous mixture of substances that melts or solidifies at a single temperature that is lower than the melting point of either of the constituents.

Answer 2

Explanation:

We get eutectic microstructures because of the preferential segregation of the two different phase elements (i.e the diffusion of the atoms during the solidification of the alloys. ... Another main reason for the eutectic formation is the surface energy of the phases (solid-liquid interface energy).
