دراسة تأثير التلدين بالتكوير على الخواص الميكلنيكية للفولاذ المتوسط التكوين

الملخص EN

The aim of present research is to study the effect of spheroidizing annealing for steel that contains (0.51% Ċ) on the hardness, wear rate, ultimate tensile strength, and ductility.

The effect of heat treatment that prier the spheroidizing annealing treatment is studied as well , that the specimens firstly is heated to the temperature equal to ( 860 Ċ), then cooled in furnace and in air ,and then carried out spheroidizing annealing treatment at the temperature equal to (860 Ċ) for (6 h), it is show that the process of spheroidizing annealing decrease hardness, wear strength, and ultimate tensile strength, and increase ductility that improve of machining properties of steel.
