As Per TTT diagram, the time interval between Y-axis of temperature to the nose of curve is Incubation period of TTT diagram. Incubation period increases with inncreasing Carbon content but upto 0.8% but the it decreses(In Fe-Fe3C Phase diagram. the curve(A3) between Austenite and Aust-Ferrite transformation at 727 degree decreases means stability of Aust. will increase but then after with increasing carbon the curve(Acm) rises up so Aust. Solubility decreases.). Austenitic Stabilizers increase Incubation period.
difference between Strain-stress diagram of copper and steel?
quenching
In EN19T steel, the 'T' stands for "treated." This indicates that the steel has undergone a heat treatment process to enhance its mechanical properties, such as hardness and strength. This treatment typically involves processes like quenching and tempering.
can we reduce the heat treatment time in carbon steel through normalizing instead of annealing?
stainless steel
pls refer to carbon-phase diagram... mild steel will be liquid and welded with temp. of >1300degC
how to increse the Tensil more than 1100 for Crmo4
Steel can be tempered (hardened by heat treatment followed by quenching -cooling).
through a utm machine tensile force is act on both bodies and check stress strain diagram and then eaisly find that who is steel and who is carbon
The phase diagram of carbon steel is important because it shows how the material behaves under different temperature and pressure conditions. It helps in understanding the different phases of carbon steel, such as ferrite, austenite, and cementite, and how they affect the material properties like hardness, strength, and ductility. By studying the phase diagram, engineers can predict the behavior of carbon steel in different environments and optimize its properties for specific applications.
