Thanks for your input guys. The hammers fractured at the eye about which they pivot. This hole extended from 130 to 160mm longitudinally during which time cracks propergated at 10 oclock and 2 oclock at the edges of the hole. This caused lateral spreading and work hardening to occur. The...
What affects the ductility of AB1 material? Water-cooled electrode clamps are cracking after 2 months service. Tensile test pieces taken from the casting after servicve gave elongation values 1% (in the as-cast condition they were 13%). The chemical analysis is within specification. I know that...
This material (Hadfields Mn Steel), is a casting alloy used for wear resistant parts particularly in situations where high impact conditions are present. This is because it has the ability to workharden (the microstructure transforms to a harder phase when it is plastically deformed). In order...
