Abstract

The addition of tantalum to the inside diameter of a gun barrel would reduce erosion during firing of medium and large caliber guns. In this work, chemical vapor deposited (CVD) Ta was bonded to A723 Steel. High-density infrared (HDI) heating was employed to bond Ta to steel at 1440°C while maintaining bulk steel temperatures below the 357°C threshold for retaining beneficial compressive stresses (autofrettage). Through-thickness temperature evolution modeling was performed. Metallographic evaluation of claddings is reported. Characterization of the interface showed that metallurgical bonding occurred while keeping bulk temperatures low.
