Abstract
A method of making a test coupon using a mold is provided. The mold defines a mold cavity that comprises a first-grip-portion cavity, a second-grip-portion cavity, an intermediate-portion cavity, interconnecting the first-grip-portion cavity and the second-grip-portion cavity, and runner cavities, directly interconnecting the first-grip-portion cavity and the second-grip-portion cavity and not directly connected to the intermediate-portion cavity. The method comprises injecting feedstock material, comprising a metal powder, into the mold cavity to form a monolithic precursor test coupon in the mold cavity, wherein the monolithic precursor test coupon comprises a first grip portion, a second grip portion, an intermediate portion, and runners. The method also comprises removing the runners from the monolithic precursor test coupon.
