Poly-crystalline MgB2 films have been grown on niobium substrate by using the hybrid physical-chemical vapor deposition (HPCVD) with a thickness about 1.5μm,which have good transport performance with Tc=39.37K,ΔTc=0.45K. Films are composed of regular plate-shape hexagonal MgB2 crystallites and have lattice constants approaching the bulk values. For this sample,the bending test has been also performed,and it can be found that the film adhered on the substrate firmly and could keep its superconductivity after bending to 120°.
