The mechanical properties of a final product are directly influenced by the solidification process, chemical composition heterogeneity, and thermal variables during solidification. This study aims to analyze influence on microstructure, hardness, phase distribution CuMn11Al8Fe3Ni3. alloy was directionally upward solidified from temperature 1250 °C. Heat extraction occurred through water-cooled AISI 1020 steel interface. were recorded using data acquisition system, with monitored at seven different positions, where cooling rates varied 13.03 °C/s closest position 0.23 farthest. Brinell hardness decreased 199 HB highest rate 184 slowest position. indicates that higher increase alloy, which can be attributed stabilization metastable β refined equiaxial grains due iron addition. Vickers microhardness observed in regions subjected slower (244 HV) compared faster (222 HV). Therefore, correlation between provides valuable insights into relationship microstructure CuMn11Al8Fe3Ni3 alloy.
