OVERCOOLED AUSTENITE STABILITY DETERMINATION METHOD |
摘要 |
FIELD: metallurgy, namely methods for determining influence of outer actions upon stability of overcooled austenite of low- and mean-carbon steels. ^ SUBSTANCE: method is designed for determining influence upon stability of austenite stresses applied to sample, selected modes of hot and warm plastic deformation and cooling rate of articles. Method comprises steps of heating sample of low- and mean-carbon steel till austenite forming temperature; applying to sample load with predetermined sign and value; cooling loaded sample; measuring hardness along length of sample on two ground diametrically opposite surfaces; plotting and analyzing hardness distribution curve; according to changed positions of hardness distribution curves evaluating influence of stress-deformed state upon destruction of overcooled austenite. ^ EFFECT: enhanced accuracy of determining factors influencing upon stability of austenite. ^ 3 dwg |
