So that in the absence of external force and without surface constraints occur freedom of austenite to martensite phase transition, this process will occur non-elastic strain caused by the volume expansion is characteristic strain. Taking into account the organizational change is not exactly the rea

If you let it in a radiative forcing and surface-bound by the freedom of the maraging steel austenitic phase change, the process will occur as a result of expansion non-elastic strain, that is characteristic for contingency. Taking into account the organizational changes that are at different temper

If lets it the free occurrence austenite changes under the non-exogenic process and the non-superficial restraint to the martensite, this process will have the inelastic strain which the volume expansion will cause, namely for characteristic strain.Considered the structural transformation is carries

If its no force and no surface under the restriction of freedom of austenite to martensite phase transformation occurs, this process non-elastic strain caused by volume expansion will occur, that is characterized strain. Taking into account the transformation is carried out at different temperatures
