ABSTRACT
The necking of specimen is specifically related to thedecrease in cross section when specimen is subjected totensile strength greater than ultimate tensile strength(UTS). The strain distribution no longer hold uniformalong the gauge length. As the tensile load is applied, dueto which length of specimen increases but there is decreasein cross section.The present work laid stress on determining the tensileproperties from stress strain curve by tensile testing ofaluminium (specimen) at different range of hightemperature The tensile testing is carried out on INSTRONstatic series 600 KN. The specimens were tested atdifferent range of high temperature (Room Temperature -325 degree Celsius). True Stress and strain is calculatedusing the engineering equation. Using the values of truestress and true strain the true stress strain curve wasplotted. The polynomial equation is obtained from eachspecimen curve. The graph is plotted between temperatureand ultimate tensile strength (UTS) which indicates thatthe ultimate tensile strength decreases with the increase intemperature.
