Report on Design for Test Coupons for Steel Castings
Abstract
Several designs of test coupons were cast and their efficiencies in producing satisfactory blanks for tensile tests were compared on the basis of mechanical properties and economy of yield. Coupons of the cloverleaf type in which the tensile blanks are spaced around a central section not only give properties equal to or better than those of other more conventional types, but require much less riser metal per specimen. The blanks may be readily removed by a cold saw or touch. The use of necking cores for facilitating removed of blanks from coupons was investigated and while not fully satisfactory showed some promise of utility. The meaning and limitations of coupons testing are discussed briefly.
