Relaxation of anisotropic alkali metaphosphate glass

•Anisotropic metaphosphate glass has highly oriented chain structures.•The anisotropic glass shows a minimum in storage modulus around Tg.•The unusual behavior is caused by deformation and shrinkage in the chain direction.•The deformation is due to weakening of bond strength between the chains below...
