Abstract In order to study the microstructure and transformation mechanism of martensite under high pressure quenching,the effect of high-pressure quenching on martensite structures and mechanical properties of industrial pure iron was analyzed by means of SEM and EBSD. The high-pressure heat treatment of industrial pure iron was carried out by a CS-1 V hexahedron pressure facility under 3,4 and 5 GPa. The results show that the martensite can be obtained by quenching the industrial pure iron at 6 ℃/s after austenitizing under GPa-level pressure. At 3 GPa,the quenched martensite structure of industrial pure iron presents typical low carbon martensite morphology. Its formation process is similar to that of plate martensites at 4 GPa,the preformed lath bundles penetrate the whole austenite grain which is divided,and then the subsequent lath bundles formed are limited. At 5 GPa,the "cooperative matrix" of martensite which transforms from parent phase to new phase in a cooperative way is large in number,small in size and neat,and most of them grow in trapezoid shape. The mechanical properties of industrial pure iron quenched at 5 GPa are close to that of 0.2% C steel quenched at atmospheric pressure,with hardness of 415HV and yield strength of 700 MPa.
