Abstract
The Al‐Zn‐Mg alloy comes under the aluminium alloy; it possesses good capability of age hardening and superior strength in contrast to other alloys. The numbers of creep aging experiments are conducted with the support of different temperature levels such as 180, 200, and 2000°C. The effects of tests are reflected on the tensile test and fatigue tests; the temperature and stress directly affects the creep characteristics, mechanical strength, and fatigue performance of the Al‐Zn‐Mg alloy. The time period of the creep test is maintained as 15 hrs with constant load of 200 MPa and 220 MPa. The increasing temperature increases the tensile strength and fatigue life of the Al‐Zn‐Mg alloy under initial condition; furthermore, continuous increment reduces the strength and fatigue existence. In the fatigue test, the fatigue span of the Al‐Zn‐Mg is extremely enhanced by the application of creep aging at a particular temperature. The 3D profilometry image visibly shows the influence of temperature in forming a fracture in fatigue analysis through microstructure analysis.
Highlights
Creep aging is one class of forming process with merger of creep deformation and aging of material, both improve the material properties and life time of working. is creep aging process concentrated on fabrication of aircraft panels and more integral parts [1,2,3]
Creep aging process is a method of heat treatment in the forming process with creep action; the material for creep aging is loaded in elastic nature in a gripper. e loaded elastic material is kept in a temperature set for a predetermined time period [4, 5]. e constant load and under in thermal exposure of the material elements of the metal are undergone to impulsive and change of microstructure and the mechanical properties of the Al-Zn-Mg alloy
From the creep aging process, the change of the material properties and the spring back effects of the materials are easy to control [6]. e materials containing aluminium alloys and combination of elements such as copper, magnesium, and zinc are used in the industry. ese alloys are developed by heat treatments; these
