Abstract: A system for sulfide stress cracking testing comprises an enclosed testing chamber including a fluid bath comprising a liquid saturated with hydrogen sulfide gas. In addition, the system comprises a test fixture disposed in the testing chamber and at least partially submerged in the fluid bath. The test fixture includes a housing having an internal chamber in fluid communication with the fluid bath and a test assembly disposed in the internal chamber. The test assembly comprises a first upper support and a second upper support, a first lower support and a second lower support, and a first platen engaging each of the upper supports and adapted to transfer an applied vertical load to the upper supports. Further, the system comprises a test specimen mounted in the test assembly between the upper supports and the lower supports.

Abstract: A golf putter head is disclosed wherein the putter head has a sole that defines an arcuate surface in two directions—from the toe to the heel and from the tail or rear end of the putter head to the putter face. As a result, the position of the putter head, hosel and shaft may be moved by the golfer without adversely affecting the performance of the putter. Further, the arcuate surface of the sole from the tail to the putter face reduces drag or friction in the event the putter head strikes the ground before striking the ball. The arcuate surface of the sole also provides for improved face balance of the putter head.
