Abstract

Heat treatment can be defined as the heating and cooling of metals to change their physical and mechanical properties, without letting it change its shape. In addition, heat treatment could be said to be a method for strengthening materials but could also be used to alter some of the mechanical properties such as improving formability and machining. On this research about the study of mechanical properties of heat treated copper using hardness and tensile test, the sample of the copper will be divided in two group which is two sample of copper dogbone with heat treated and two sample of copper dog bone wihout heat treated. In addition, the two sample of copper dogbone will undergoes the heat treatment in furnace. For the hardness testing, there were two methods used which is Rockwell method for the copper without heat treated and Vickers method for the copper with heat treated. after that the samples will undergoes the tensile test to determine the strength of the material. For objectives this research is about to determine the properties of the copper in dogbone dimension after heat treated and with the non heat treated. Furthermore this research also can be analyze and recorded the value of max load, ultimate tensile strength and Young’s Modulus required to break the sample during the tensile test. Another objective is to determine the capability of using the Rockwell methods hardness for the samples copper with heat treated. Based on the result of the tensile test, it prove that the copper with heat treated more ductile than the copper without heat treated. So we can conclude that the heat treatment will give effect towards copper properties.
