Abstract

Light metal alloys are extensively used in automotive, aerospace, aircraft, and military sectors since their lightweight leads to reduced energy consumption, increased fuel efficiency, and better environmental protection. In the present situation, nanomaterials are the potential candidate for weight saving in the structural application and can meet stringent government norms. Nanomaterial was heat-treated in the furnace to about a certain temperature and time and then normalized for strengthening. The heat-treated nanomaterial undergoes different forging processes, namely, hot forging and cold forging, using a certain capacity’s hydraulic press. Hence, in this work, an extensive study on the influence of the prestrain annealing, the corrosion rate on differently treated samples, and the effect of sensitization heat treatment on the nanomaterial was done.

Highlights

Until cooling, the nanomaterial must be heated above its recrystallization temperature for a specified period
Ni, Ti, Zn, and Cr are commonly used as minor addition in the aluminum matrix, and their composition varies dependent upon the applications
Metal brittleness is reduced while their magnetic properties and electrical conductivity are improved by the heating and cooling process [7]

Summary

Introduction

The nanomaterial must be heated above its recrystallization temperature for a specified period. The crystal grain size and phase composition determined by the heating and cooling rates dictate the nanomaterial properties [4]. In the hot or cold working annealing process, the metal parts change the nanomaterial structure again so additional heat treatments can be needed to achieve the desired properties [6]. Metal brittleness is reduced while their magnetic properties and electrical conductivity are improved by the heating and cooling process [7].
