TY - JOUR ID - TI - Study the Effect of Spheroidizing Annealing on Mechanical Properties of Medium Carbon Steel دراسة تأثير التلدين بالتكوير على الخواص الميكانيكية للفولاذ المتوسط الكاربون AU - فراس فرحان سيد PY - 2011 VL - 29 IS - 1 SP - 45 EP - 54 JO - Engineering and Technology Journal مجلة الهندسة والتكنولوجيا SN - 16816900 24120758 AB - The aim of present research is to study the effect of spheroidizing annealingfor steel that contains (0.51% Ċ) on the hardness, wear rate, ultimate tensilestrength, and ductility. The effect of heat treatment that prier the spheroidizingannealing treatment is studied as well , that the specimens firstly is heated to thetemperature equal to ( 860 Ċ) , then cooled in furnace and in air ,and then carriedout spheroidizing annealing treatment at the temperature equal to( 860 Ċ ) for ( 6 h ) , it is show that the process of spheroidizing annealingdecrease hardness, wear strength , and ultimate tensile strength , and increaseductility that improve of machining properties of steel .
