Abstract	ZrH$_{2}$-doped MgB$_{2}$ wires, with the component of Mg:ZrH$_{2}$:B= (1-x):x:2(x = 0, 5, 8, and 10%), were fabricated through thein situ powder-in-tube method by using low-carbon steel tube as the sheath material Samples were sintered at 750$^{^}$C for 1h in a flow of high-purity argon.The lattice parameters a and c of MgB$_{2}$exhibit a little decrease with the doping of ZrH$_{2}$.J$_{c}$(B)property of MgB$_{2}$wires are improved gradually with the increase of x, reaches the best whenx = 8%, but decreases significantlywhen x = 10%. The decrease of MgB$_{2}$grain size, the excellent grain connection, and the substitution of Zr$^{4+}$for Mg$^{2+}$which is caused by the doping of ZrH$_{2}$, are responsiblefor the enhancement of J$_{c}$(B)property forthe doped MgB$_{2}$wires.
