isothermal transformation

Isothermal transformation is a process where a material, like metal, changes its internal structure at a constant temperature over time. When steel cools down from a high temperature, its atoms rearrange, affecting its hardness and strength. By holding it at a specific temperature, the transformation happens steadily and predictably. This controlled change allows engineers to improve the material's properties for different uses, such as making steel tougher or harder. Essentially, isothermal transformation is a way to carefully manage how a material's structure evolves by maintaining a steady temperature during the process.
