Abstract
Standards for non-destructive testing methodologies and methods of fabricating the standards are disclosed herein. The standards include a void-defect coupon that includes a spheroidal void and an elongated void. The spheroidal void has a maximum dimension and a spheroidal void volume. The elongated void had a longitudinal dimension, a maximum transverse dimension, and an elongated void volume. The longitudinal dimension of the elongated void is greater than the maximum dimension of the spheroidal void. The maximum transverse dimension of the elongated void is less than the maximum dimension of the spheroidal void. The methods include forming a first void-defect coupon and forming a second void-defect coupon.
Claims20
A standard for evaluating non-destructive testing methodologies and fatigue durability performance, the standard comprising a void-defect coupon that comprises:
- a spheroidal void, having a maximum dimension and a spheroidal void volume;
- and
- an elongated void, having a longitudinal dimension, a maximum transverse dimension, and an elongated void volume;
- wherein:
- (i) the longitudinal dimension of the elongated void is greater than the maximum dimension of the spheroidal void;
- and
- (ii) the maximum transverse dimension of the elongated void is less than the maximum dimension of the spheroidal void.
A method of fabricating a standard for evaluating non-destructive testing methodologies, the method comprising:
- forming a first void-defect coupon utilizing a first powder metallurgy process, wherein the first void-defect coupon includes a first-coupon void having a maximum dimension and a volume;
- and
- forming a second void-defect coupon utilizing second powder metallurgy process, wherein the second void-defect coupon includes a second-coupon void having at least one of a maximum dimension that is greater than the maximum dimension of the first-coupon void and a volume that is greater than the volume of the first-coupon void.
