STUDY FOR THE VARIATION OF HARDNESS AND RESILIENCE CHARACTERISTICS AFTER HEAT TREATMENT FOR STAINLESS STEELS
Journal Title: TEHNOMUS - Year 2011, Vol 18, Issue 1
Abstract
The paper presents tests of the stainless steel. This material was subjected to heat treatments, afterwards conducted impact bend tests and hardness measurements. Using the data was drawn graphic variation of hardness and resilience depending on the condition of structural material (hardened, annealed, solution treated and aged).
