heal.abstract	The superconducting properties of ex situ and in situ powder-in-tube (PIT) steel-sheathed MgB2 superconductors fabricated by different manufacturing techniques are examined. Significant improvement in the critical current density of the explosively densified sample is observed against the corresponding Jc characteristics of the extruded specimens, reaching approximately 3.8 × 105 A cm-2 in 3.2 T field at 5 K. The high Jc values are maintained at fields above 5 T, which suggests that degradation of the material properties takes place at a later stage, making the superconductor ideal for practical applications. The quasi-statically consolidated specimens exhibit a more typical behavior where increase of the compaction level results in an enhancement of their Jc characteristics. © 2010 IOP Publishing Ltd.	en
