OVERLAP, CLEARANCE AND SPECIMEN WIDTH OF BRAZED PH15-7MO JOINTS.
Abstract
Tests were conducted to evaluate the shear strength of brazed joints with thin sheets of base metal, and to determine the shear strength variation as caused by joint clearance and length of overlap. PH 15-7 Mo stainless steel was selected as the base metal, and Lithobraze 925 as the braze alloy. At minimum joint clearance, an increase in overlap caused a reduction in the shear strength, determined at both room temperature and at 800F. The maximum shear strength developed at room temperature (20,700 psi) resulted from a 5t overlap; the maximum developed at 800F resulted from a 3t overlap. The effect of joint clearance was not determined due to the severe surface contamination encountered on all exposed PH 15-7 Mo surfaces. Since the braze alloy flow and filleting on the exposed base metal surfaces were unsatisfactory, testing was discontinued. (Author)
