... Abstract Operation handles produced from C45 steel showed many fine cracks at the flame hardened noses. The cracks ran from the corners of indentations caused by the tool during alignment. Metallographic investigation showed the nose was overheated during flame hardening. It was concluded...

..., in the horizontal and vertical planes during the testing. The fracture was revealed to have occurred in bend 2. An indentation, presumably caused by the bending tool during forming, at the inner surface of the bend where fracture occurred was revealed by microscopic examination. Spiral marks produced on springs...
