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.
