Texture of Zirconium Alloy and Its Effects on Properties

Zirconium alloys are generally employed as structural components and fuel cladding in nuclear reactors.The texture influences many application properties of zirconium alloy.Therefore,the investigation and control of texture are very important to the development and utilization of zirconium alloys.The plastic deformation system(slip and twin) of zirconium alloys,the texture control methods of plates and tubes,the effects of rolling temperature on texture of plate and the influence of annealing on texture of zirconium alloys were reviewed.The relationship between texture and properties such as yield strength,creep strength,iodine-induced stress corrosion cracking,orientation and distribution of hydrides and irradiation growth of zirconium alloys were summarized.
