Good Morning fellow Engineers
I am looking for someone who has some experience with Ultrasonic Impact treatment for increase fatigue resistance in welds. I would like to hear this person’s opinion on the treatment particularly with carbon and low alloy steels.
Thanks
Recently we have had problems with quench cracking of cold finish 4140 bar. The heat treater claims there are tiny surface fold conditions present from the cold finish process that cause the quench crack. Metallographic examination so no surface conditions associated with the crack initiation...
Does anyone have any experience with heat treating Aluminum Bronze C95400? Heat treatable grades of Aluminium Bronze contain 9.5 to 11.5 % Al, with iron , small amounts of nickel and manganese. The reason for heat treating is increasing tensile strength and hardness with improved impact...
Back sometime in early 2007, I read a thread which discussed digital camera attachments and software for metallurgical metallographic uses. As I remember this equipment was considered to be the best. I just cannot remember the products name. Recently I purchased a used Nikon Epiphot which I...
