  • Maraging Steel - an overview | ScienceDirect Topics

    The rate of cooling is of less significance because formation of martensite in maraging steel is inevitable as per dictates of CCT diagram. However it is to be understood that the cooling must be carried out till room temperature, so that martensite formation is envisaged. Because maraging steel is quite strong and the volume change in ... So for example a spanner would have a central part where the grain structure is elongated but with few dislocations then the grain flows around following the form of the ends. The spanner will of course have to be heat treated to give the right degree of hardness and toughness at the right points.

In high power lasers there is a possibility of ionisation of the metal vapour which may lead to the formation of plasma above the workpiece sur­face that may absorb the laser beam with consequential reduction in penetra­tion depth. This is usually avoided by making helium gas flow over the spot to sweep the ions causing the plasma formation.

  • Bainite - Wikipedia

    Bainite is a plate-like microstructure that forms in steels at temperatures of 125–550 °C (depending on alloy content). First described by E. S.
