The impact of Deep cryogenic treatment (DCT) on the metallurgical and mechanical properties of Al6061-T6 is examined in the present work. The combination was subjected to Deep CT at - 196 ºC for 36 h. Mechanical tests, for example, Brinell hardness test, ductile, and weakness tests were performed on both local and treated examples. It was watched that the mechanical properties, for example, hardness, yield quality, and extreme rigidity expanded by around 41, 27, and 13%, separately, for the treated example. The treated amalgam was portrayed by utilizing the procedures, for example, optical microscopy, vitality dispersive x-beam spectroscopy (EDS), and to watch the adjustments in the metallurgical highlights. SEM-EDS comes about show precipitation, better dissemination of second-stage particles, and higher separation thickness in the regarded compound when contrasted with the untreated composite. The treatment confers enhanced hardness and quality to the compound because of precipitation solidifying and high separation thickness. Break morphologies of the treated and the local examples were portrayed by utilizing examining electron microscopy and it was watched that the striations were denser in the treated example supporting the higher weariness quality
