Yes, it is true. Some materials, known as shape memory alloys (SMAs) or shape memory polymers (SMPs), can return to their original shape after deformation when exposed to a specific temperature. This effect occurs due to a phase transformation in the material’s crystal structure or molecular arrangement. Examples include nickel-titanium (Nitinol) alloys and certain polymers.
