内容简介

At present, novel iron-based magnetostrictive materials have become a research field of great concern due to their excellent comprehensive properties and broad application prospects. This book focuses on the preparation technologies and applications of novel iron-based magnetostrictive alloy rolled sheets. It briefly discusses the physical principles and functional characteristics of magnetostrictive materials, the development and classification of these materials, and their relationship with modern high and new technologies, as well as provides an overview of iron-based magnetostrictive materials. The book mainly discusses the mechanical properties of magnetostrictive Fe-Ga alloys, the deformation and microstructure evolution of Fe-Ga alloys during the rolling process, the recrystallization and magnetostrictive properties of Fe-Ga alloy rolled thin sheets, the mechanism and influencing factors of abnormal growth of (110)-oriented grains in Fe-Ga alloy rolled sheets, and the preparation and properties of Fe-Ga alloy rolled thin strips. In addition, this book introduces the applications of Fe-Ga alloy rolled sheets and strips.
