155-MM M284 Gun Tube Failure

Abstract

In June 1989 a failure occurred during a routine straightening operation of a 155-mm M284 gun tube on the straightening press. The Advanced Engineering Branch of Benet Laboratories performed a material evaluation of the gun tube forging (serial no. 0242). The results revealed that the gun tube material met the specified mechanical (with the exception of percent reduction- in-area) and material requirements. Evidence showed that the failure was due to a quench crack. In addition, it was determined that a forging defect acted as a stress concentrator for the quench crack Failure, Forging, 155-mm M284 Failure, Forging Defect, Quench Crack.
