Sinter Rotary Forging: Part One

Sinter rotary forging is one of the prominent sinter forming processes and uses pressed and sintered metal powder preforms as starting material. The sinter forming technique combines the advantages associated with two well-known techniques, namely powder metallurgy and conventional forming. Continue reading

Intercritical Annealing of Ductile Iron: Part One

Heat treatment can be performed on ductile iron to increase strength, wear resistance, ductility, toughness, and/or improve machinability by controlling the matrix microstructure. In F, an intercritical heat treatment starts with partial austenitization in the intercritical region where ferrite and austenite are present. The amount of austenite depends on the chemistry of the alloy and the temperature. Continue reading
