Abstract
X-ray lattice strains were investigated in an AISI M3:2 PM high-speed steel in the as heat treated condition and after exposure to alternating mechanical load. The volume changes during heat treatment were monitored with dilatometry. Hardened and tempered AISI M3:2 steel consists of tempered lath martensite and the carbides M6C,V8C7 and M23C6.
In the as heat treated condition the stress state is triaxial. The primary carbides M6C and V8C7 experience a compressive state of stress. Exposure to an alternating mechanical load, changes the states of stress of V8C7 and tempered martensite, but does not appear to change the state of stress in M6C.
