Microscopic analysis of the Cu-Al-Mn-Ni shape memory alloy after heat treatment
In this work, the microstructure of two nickel content (2.5 and 3.5 wt.%) Cu-Al-Mn-Ni shape memory alloy (SMA) after heat treatment was analyzed. The melting of technically pure was performed in specially designed copper anode which also was used as a casting mould. By this procedure, samples of cylindrical shape, ingots of 8 mm diameter and 15 mm length, were produced. The samples with various nickel content (2.5 and 3.5 wt.%) were subjected to heat treatment procedure. Selected samples were heat treated at 900 °C, held for 15 minutes on that temperature following water quenching. Optical and scanning electron microscopy revealed the presence of β'1 martensite in the microstructure. Microhardness of the samples increase drastically by increasing the nickel content from 2.5 to 3.5%, respectively.
