Martensite steel bonded carbide Isothermal Quenching
Over the latter more than double the amount of austenite is no bouncing main reaction notched impact fracture toughness of the text pre-crack formation stage r) energy absorption capacity of the sample, which is not notched impact strength of the main reaction of the success of the pendulum-shaped crack text from the impact test. Value of their contribution to the greater plasticity than the intensity so that,; 00c isothermal quenching organization is more residual austenite spring the main reason leading to higher values. Comparison of the two fracture surface (Figure 3 shows, 200 ℃ isothermal quenching more impact off the mouth and thick long tear ridge. Local area there is the appearance of shallow little tough Apartments (ring 3a) and directly offend the fire back to +200 c the impact of state fire tear off the mouth of the step edges and thin short 'Figure 3b) have also confirmed the value of residual austenite on the contribution of m 200 ℃ isothermal quenching state. c value of the direct quenching of low dry +200 ℃ tempered the main reason may lie in martensitic state and the state of stress. 200 \Caryopteris these basic tempered martensite toughness is not low, short-tailed bird with the residual toughness of Albright's a great disparity.
