A nitriding heat treatment of a BCC steel normally requires 2 h at 600 °C. What temperature would be required to reduce the heat treatment time to 1 h?(Q =76570 J/mol, Do =0.0047x10- 4 m2/s) and the last one. thanks for ur helping.
A.2 (i) (ii) Explain how an understanding of the creep failure mechanisms of high temperature nickel alloys has led to alloy and manufacturing developments which have resulted in an increase in the maximum operating temperature of a jet engine turbine blade. If we quench a plain carbon steel we can produce a very strong/hard and yet brittle material. Why does the quench lead to this change in properties, and what subsequent heat treatment would enable us to mostly retain the high strength whilst improving the ductility? Explain the effects of your proposed heat treatments in terms of the phase changes and microstructural features developed at each stage.
Excellent combinations of hardness, streneth, and toughness are obtained from bainite. One heat treater austenitized a eutectoid steel at 750°C, quenched and haid the steal at 250°C for 15 min, and finaly permitted the staal to cool to room temperature. Did he produce the required bainitic structure? Use the diegram below in your answer Answer: Tie ReckvellChndre
