THE RESEARCH OF THREE DIMENTIONσ－Tlnε0/ε－D(-1/2) COLD BRITTLE CONTROLLING DIAGRAM AND MECHANISM’S DIAGRAM

Abstract

Abstract: In this paper, the comprehensive relationships among yield strength, σys, fracture strength, σj, parameter, A (A＝Tlnε0/ε) and grain size, DD-1/2, are researched in theory and experiment in tensile specimen of 38CrA steel. Three dimention σ－Tlnε0/ε－D-1/2 cold brittle fracture controlling diagram and fracture mechanism’s diagram are established. They can be used in not only analysis, diagnosis, calculation, control and prevention of cold brittle fracture, but also the design, choice of materials and safe evaluation of parts in low temperature.

Key words: 钢, 冷脆断裂, 三维
