Effects of Casting Technique on Microstructure and Connection Mechanism of Super-high Manganese Steel Composite Hammer Prepared by Casting Process
A side-riser which feeds two hammers becomes a top riser which feeds a hammer.The microstructure,compositions and connection mechanism of connection zone between cemented carbide-super high manganese steel,and the microstructure of the matrix are researched by SEM and energy spectrum.The experiment results show that the grain of hammer matrix is refined;the connection between cemented carbide-super high manganese steel is close;the connection mechanism is diffusion bond.
