If a γ solid solution is quenched in water it results in intense local lattice strains that block movement of dislocations. The degree of hardness of a quenched austenitic structure is proportional to the lattice strain. There are two ways of overcoming the brittleness of a quenched martensite steel. Property changes with tempering of a martensitic carbon steel strongly depends on the temperature at which tempering is carried… <Read in Full>
Microstructure evolution during Heat treatments on low-carbon steels In low-carbon steels, the transformation from γ- to α- iron takes place between 723 and 910°C and annealing can be carried out above or below this temperature range. The temperature chosen will have a significant influence on the structure produced. The effect of the transformation can be both beneficial and detrimental to the properties of a steel. There are two variations of the annealing process used with steels: Full annealing and Normalizing… <Read in Full>
Heat Treating Industry Technology Roadmap The "1999 Research & Development Plan of the ASM Heat Treating Society" was issued as a starting point for implementing the heat treating industry's "Vision 2020" technology challenges. A key element in achieving the R&D objectives is the timely delivery of results in an attempt to attract strong industry support, both short-term and long-term... <Read in Full>
