Originální abstrakt
Tensile tests of an unalloyed ADI with the matrix created by upper bainite containing from 30 to 35 % of retained austenite were performed in a temperature range -196 to +200 C. The temperature dependence of true fracture stress, elongation to fracture, and reduction in area is separated into three regions. Unmonotonous temperature dependence of yield points defined by plastic strain from 0.05 to 2 % in the middle region is the evidence of the stress induced phase transformation of retained austenite into martensite before these values of plastic strain are reached.
